There are several categories of options available through the Options dialog box.  Click on the category about which you want to learn more:

Popular Options

Image Options

Prompt before closing: Select this option and Image-Pro prompts you to save images before you close them if they have changed since you last saved them. Uncheck this option and Image-Pro will close the images as soon as you invoke the Close command. If unsaved changes had been made, they will be permanently lost.

Auto-Shutdown

Enable Auto Shutdown: The Auto Shutdown feature enables Image-Pro to automatically shutdown after a predetermined time interval of inactivity. Once the inactivity time point is reached, a message is displayed asking if the user would like to continue working. If no response is recieved, Image-Pro automatically shuts down after a predetermined time.

If unsaved images are open when shutdown occurs and the option Save Auto Recover information is on, the images will be automatically saved and available for recovery when Image-Pro is restarted. The Save Auto Recover information option is located under the File/Options/Image Saving menu and is set to ON by default.

  • Network License: The feature is ON by default and will return the Image-Pro seat.
    Default settings: Auto Shutdown Timer 60 minutes and Prompt Timer 5 minutes.
  • Non-Network License: The feature is Off by default and will return the Image-Pro seat.
    Default settings: Auto Shutdown Timer 60 minutes and Prompt Timer 5 minutes.
  • Enable Auto Shutdown: Enable auto shutdown based on Image-Pro inactivity.
  • Auto Shutdown Timer (min): Initiate the auto shutdown process after a period of Image-Pro inactivity.
  • Prompt Timer (min): The prompt dialog will be displayed for the selected time to confirm shutdown.

Identities

Enable Application Configuration through User Logon at startup: Enabling this option will cause Image-Pro to prompt for users to select an identity at startup. Identities are user access IDs. Image-Pro remembers application settings, layouts, and options for each identity. When identities are enabled, it allows users to customize their workspaces individually and have those customizations restored each time they access Image-Pro.

Require Password to Enable Identity: Enable this option to assign a password to each identity. When enabled, Image-Pro will not open unless the correct password is entered for the selected Identity.

When this option is first selected Image-Pro will show a dialog in which the administrator’s password must be entered.

With this option selected, only the administrator has the option to Add, Duplicate and Delete identities, and to manage the passwords for all identities (non-administrators can manage their own password). Without this option selected, all users can complete these actions.

Note: Access IDs are not secure, even with the option to require passwords selected. If you wish to add secure (password protected), user based access to Image-Pro, we recommend that you do this by adding users to Windows.

To create a new identity, click Add. Enter a name for the new identity in the dialog that opens and then click OK.

To delete an identity, click on an existing identity and click Delete.

You can duplicate an existing identity by selecting it from the list and clicking the Duplicate button. Enter a new name for the duplicate identity and Click OK.

To manage the password for an identity, select the identity from the list and click Password. Enter and confirm the password and click OK.

Image Options

General

Maximum number of undo's: The number you set here determines the number of Image-Pro operations you can Undo.  For example, if you enter '5', you will only be able to undo the last 5 operations you performed.  Undo buffers use memory, and when you are working with large images, undo buffers can increase the time it takes Image-Pro to perform some operations.  Depending on your memory availability, and the speed of your CPU, you may want to change the buffer value from its default of 50.

Opacity of inactive overlays (%):  When an overlay (for ROI, annotations, measurements...) is inactive it is displayed semitransparent.  This option allows you to control how opaque inactive overlays will appear.

Prompt before closing: Select this option if you want Image-Pro to prompt you before closing an image that has been modified since it was last saved.  Uncheck this option if you want Image-Pro to close a modified image immediately (the image will not be saved, and Image-Pro will issue no warning).

Restore Documents Workspace:  Select this option and Image-Pro starts up to the configuration of open images and documents as they appeared in the application workspace the last time it was shut down. If you uncheck this option, Image-Pro always opens to an empty workspace.

Display Zoom as effective magnification (Lens Mag. * Zoom): Select this option to display the workspace zoom factor as effective magnification when the effective magnification is known.

Image Display

Auto Zoom:  Select "Best Fit" to tell Image-Pro to zoom images to fit the application workspace when they are initially opened or created new.  This selection overrides the selection in the Default Zoom control (described below).  If you select "Default Zoom," the value specified for Default Zoom is used for sizing images when they are first opened or created.

Default Zoom:  Defines the initial zoom factor you want Image-Pro to use when images are initially opened or created new.  Note that this value is not used if Auto Zoom (described above) is set to "Best Fit."

Inherit Magnification Settings: When this option is selected, Image-Pro applies the magnification settings of the source image to images cut, copied, or cropped from it. For example, suppose the source image is scaled in the application workspace to 28% and you draw and ROI in the image and then click on the Crop tool. Image-Pro creates a new image in the application workspace that contains only the pixels of ROI. If the Inherit Magnification Settings option is selected, the new image is scaled to 28%; if the Inherit Magnification Settings option is not selected, the new image is scaled to be maximized in the workspace.

Default Sequence View: Select which of the different ways to view sequence files you want to use as the default for viewing sequence files:

  • Image: This view presents the sequence like a movie that you can play.
  • Gallery: This view presents a 'storyboard' of the frames of the sequence so that you can view all frames simultaneously.
  • Slicer: This view presents the image sequence using volume cross-sections in XY,YZ and XZ planes
  • 3D: This view presents a 3D view of the sequence of images, such that the sequence of frames is used to construct the Z axis.

Confine labels to image: Unless drawing is allowed outside of image bounds, do not display labels outside of the image bounds.

Allow mousewheel scaling: When hovering over a selected annotation or ROI, the mousewheel will scale aspects of the selected object rather than the zoom.

Cross Bars

Annotation: Display cross bars on the annotation overlay for lines and polylines.

Line Profile: Display cross bars on the line profile overlay for lines and polylines.

Set Display

Auto Tile: Automatically show tiled images if image set contains XY dimension with positioned tiles.

Flip Left-Right: Use reverse tiling order in horizontal direction.

Flip Top-Bottom: Use reverse tiling order in vertical direction.

Blend Overlaps: Combine overlapping tiles with a gradient blend; if not set, no blending is done (faster but not as pretty).

Surface Plot

Render to bitmap:  Enable this option only if surface plots are not being displayed correctly due to problems with OpenGL support on the video card.  This option disables OpenGL's rendering window. 

Application Options

General

Automatic Update Check: Select this option and Image-Prowill check for application updates on startup.

Help improve this product: Help improve this product by sharing anonymous diagnostic information.

Display

Auto Show Measurements Data Table:  Select this option to have Image-Pro automatically show the Measurements data table when the first measurement is made.

Individual Object Display Limit: The value you enter here tells Image-Pro the maximum number of objects per segmentation class generated by a Count operation that are permitted to be displayed individually. If the number of objects exceeds this limit, they will be displayed as a single bit mask, which is a faster way to display multiple measurement objects. In this mode multiple object selection will not be displayed on the image.

Object Count Undo Limit: The maximum number of measurement objects on the image to be backed up for undo. If the number of objects exceeds this limit, the undo of measurements is not created when objects are added or modified. This option can be used to speed up measurement editing when there is a large number of objects.

Show Date/Time Stamp: Select this option to display the date/time stamp on images.  The stamp shows the current time on live previews and the frame time on captured images.

Tint Shortcuts: Select the colors you would like to use as the three tint shortcuts. The tint shortcuts are the left-most tint tools of the image context menu (shown by right-clicking anywhere in an image).

Space Navigator

Sensitivity: This option controls the sensitivity of the Space Navigator mouse.  The higher the number, the more sensitive the mouse.

Reset to Default: Click this button to restore the application workspace to its default configuration of panels.

Memory Management

Memory Limit: The memory limit is the amount of memory used for image storage; once this memory is filled, the application will try to discard or page out low-priority image memory.

Maximize Free Memory: This button asks the Windows resource manager to free up as much managed memory as possible.  All on-demand loaded image memory that is not actively displayed will be discarded, and any modified image memory that is not actively displayed will be swapped to disk (see Image Swap File Folder below).

Image Swap File Folder:  You can use this text box to specify the preferred location for storing temporary files created when swapping out image memory.  For example, if you specify "C:\Temp" then temporary files will be stored in that folder.  If left blank, the default system temporary directory will be used.

Max Undoable Image Size:  In order to avoid wasting image memory by placing copies of large images on the undo stack, image data larger than this percentage of the Memory Limit are not kept for Undo. If you are finding that modification steps which you want to restore from the undo stack are being shown as discarded, you probably need to increase this value.

File Options

General

Prompt for filename for new documents:  If "On," Image-Pro prompts you for a filename whenever you go to save or close a file for the first time.  This gives you a chance to overwrite the default system-supplied name Image-Pro gave the file with a more meaningful name.  

Image Saving

Save Annotations: If selected, Image-Pro enables the storage of annotations in TIF files.  If unchecked, annotations will not be storable across sessions.

Save ROI's: If selected, Image-Pro enables the storage of ROIs in TIF files.  If unchecked, ROIs will not be storable across sessions.

Crop to ROI in Save As: If selected and an image has one or more ROIs defined, only the ROI portion of the image will be saved to a new file when you use the Save As command.  If unchecked, the whole image is always saved to a new file whether or not ROIs are defined in the original image.

Save Grid Overlay: If selected,Image-Pro enables the storage of Grid Overlays in TIF files.  If unchecked, grid overlays will not be storable across sessions.

Save Line Profiles: If selected, Image-Pro enables the storage of Line Profiles in TIF files.  If unchecked, line profiles will not be storable across sessions

Save AutoRecover information: This option enables/disables the AutoRecover feature. If AutoRecover is enabled, Image-Pro periodically stores the latest state of your files automatically, capturing any unsaved changes you have made to them in a special AutoRecover storage location. In the event your application closes prior to saving those changes through the File|Save tool, Image-Pro can restore the changes up to the last AutoRecover storage event. AutoRecover storage events will occur at the frequency indicated by the AutoRecover save frequency option (described below). The latest state of your files is stored in the location indicated by the AutoRecover file location option.

AutoRecover save frequency (minutes): If AutoRecover is enabled (i.e., the Save AutoRecover information option is selected), specify in this text box the frequency, in minutes, that you want files automatically saved.

AutoRecover file location: If AutoRecover is enabled (i.e., the Save AutoRecover information option is selected), specify in this text box the storage location where you want files automatically saved.

Image Loading

Best Fit Display: If selected, this option automatically applies the best fit display when loading images.  The Black Level is set to the intensity determined by the Low% setting. The White Level is set to the intensity determined by the High% setting.

Accumulate Best Fit: Select this option to have Image-Pro accumulate best fit frames when it does on-demand loading of files for file formats that support this feature.

Multiresolution Images Below Threshold Load as Very Large Image:  If selected, this option causes even small multi-resolution images to be opened into the Large Image Workspace.  If not selected, images that will occupy less memory than the Very Large Image Viewer Threshold will open into a normal image workspace.

Very Large Image Viewer Threshold:  This value sets the frame size above which multi-resolution images are always opened into the Large Image workspace; it is specified as a percentage of free image memory.  Images smaller than this threshold will be opened into a normal image workspace if the Multiresolution Images Below Threshold Load as Very Large Image option is not selected.

Calibrate from TIFF resolution:  Select this option to have Image-Pro calibrate open TIFF images from the TIFF resolution information.

Recent Document List Length:  This value is the number of days for which opened documents are kept in the Recent documents panel.

Quick Save for Publication

Prompt for file name:  If selected, Image-Pro prompts you for a filename whenever you save images for Publication or Analysis using the Quick Save for Publication or Quick Save for Analysis tools.  

Folder: Specifies the path and folder name where images saved using the Save for Publication tool will be stored.

File name prefix: Images saved using the Save for Publication tool are given names automatically in the format of a prefix (such as "Publication Image") followed by a sequence number.  This option allows you to specify the prefix to be used.  For example, if you specify the prefix "Publication Image" in this text box, then the first image saved using 'Save for Publication' tool will be named "Publication Image001," the second will be named "Publication Image002," and so on.

File type: Specifies the image format to be used to store images saved using the Save for Publication tool.  The default is JPG because it is a common compressed-file format appropriate for use in documents and Web pages.  But you can choose to have images saved using 'Save for Publication' tool in any one of the other supported image formats.

Output image size (0-original size, pixels): For images saved using the Save for Publication tool, this option specifies the width of the resulting stored image in pixels.  All images saved using the 'Save for Publication' tool will be scaled to the specified width.  Note that the height of saved images will be calculated based on the original image's aspect ratio so that proper proportionality is maintained.

When zero is entered for this option, this feature is disabled; image saved using the 'Save for Publication' tool will be stored with their original pixel resolution.  

Use current zoom:  When this option is active and 'Output image size' is 0, the image is captured using the current magnification.  When this option is off, the result image will have the size defined by the 'Output image size' parameter.

Auto open: When checked, images created and stored using the Save for Publication tool will be automatically open to the Image-Pro workspace at the time they are stored.  Since the 'Save for Publication' feature often effects image data due to downsizing and compression, this option is made available to allow you to check the quality of such images when they are created.

Play sound: Select this option to have Image-Pro give you a sound indication when something has completed being saved for Publication or Analysis.

Quick Save for Analysis

Folder: Specifies the path and folder name where images saved using the Save for Analysis tool will be stored.

File name prefix: Images saved using the Save for Analysis tool are given names automatically in the format of a prefix (such as "Analysis Image") followed by a sequence number.  This option allows you to specify the prefix to be used.  For example, if you specify the prefix "Analysis Image" in this text box, then the first image saved using 'Save for Analysis' tool will be named "Analysis Image001," the second will be named "Analysis Image002," and so on.

File type: Specifies the image format to be used to store images saved using the Save for Analysis tool.  The default is TIF because it is a format that does not use compression and that supports the saving of ROIs and annotations.  But you can choose to have images saved using 'Save for Analysis' tool in any one of the other supported image formats.

Paste Options

Action Options

Preview Paste: This option allows you to preview the results of the paste operation before the pasted data is 'burned in' to the image.

Preview with blend: Enable this option to view the Clipboard data as it would appear if you were to paste it with the specified Source blend percentage.  This allows you to see the effect of your blend settings while you are positioning the Clipboard data prior to actually pasting it into your image.

Apply with blend: When blending is turned on, pasted image data is 'blended' with existing image data by doing pixel averaging.  The result is that the pasted image appears semi-transparent, and the contours of both images can be discerned after the paste operation.  The pasted image data will be more or less prominent depending on the weighting value used for the blending, as specified in the Source Blend Percentage control.  When blending is turned off, pasted image data is completely opaque.

ROI After Paste

ROI after paste: This option controls how any given pasted-to ROI in a destination image is to be treated when the paste operation is completed.

  • Paste source ROI:  The destination ROI is used for placing the pasted data initially, and then it is replaced by the source ROI.
  • Keep destination ROI the same:  The destination ROI is used for placing the pasted data initially, and after the data is pasted, the destination ROI is left in the image unchanged.
  • Intersect source and destination:  The destination ROI is used for placing the pasted data initially; when the paste operation is finalized, the resulting ROI will be the overlapping portions of the source and destination ROIs.  
  • Clear destination of ROI to none:  The destination ROI is used for placing the pasted data initially; when the paste operation is finalized, neither the source nor target ROIs are retained in the pasted-to image.

Blend Control

Source blend percentage: This control is only relevant if the Apply with Blend option is set to On.  The Source blend percentage control indicates how transparent or opaque pasted image data should be.

Blend Type:   Specify the intensity values that are to be affected by the blend.  Select from the following:

  • Blend all pixels:  The Clipboard data will be applied, in the specified blend ratio, to all pixels in the paste area, regardless of their intensity.
  • Blend only Lighter Destination Pixels:  The Clipboard pixels will be pasted (in the specified blend ratio) only in places where the destination pixel is lighter than the corresponding Clipboard pixel.
  • Blend only Darker Destination Pixels:The Clipboard pixels will be pasted (in the specified blend ratio) only in places where the destination pixel is darker than the corresponding Clipboard pixel.  

Action Masking

Source ROI masking: If checked, Image-Pro pastes from the source ROI only, if an ROI exists in the source.

Destination ROI masking: If checked, pasted data will be placed inside of an existing ROI in the destination image, if one exists.

Source ROI masking (Paste New): If checked, Image-Pro only pastes from the source ROI if you use the Paste New command.     

Histogram & Profile

General

Histogram: Shows/hides a histogram of the active image in the Image Histogram window.

Dynamic: Shows/hides a dynamic representation of the active image's histogram in the Image Histogram window.  This is a virtual histogram of the image after the black level, white level, and LUT adjustments have been applied.

LUT: Shows/hides a graphical representation of the active image's brightness, contrast, and gamma adjustments in the Image Histogram window.

BW Levels: Shows/hides the dotted vertical bars representing the active image's black level and the white level in the Image Histogram window.

View

Axis X: Shows/hides the X axis values along the bottom of the active image's histogram in the Image Histogram window.  

Axis Y: Shows/hides the Y axis values along the left side of the active image's histogram in the Image Histogram window.

Statistics: Shows/hides the Statistics table in the Image Histogram window.  Also, provides options for the placement of the Statistics table within the Image Histogram window.

Options

Ignore ROI: If selected, Image-Pro displays histogram data for the entirety of the active image, regardless of ROIs that have been defined.

Active frame: This option is only relevant for sequence files.  If selected, Image-Pro displays histogram data for only the active frame of the sequence file.  Otherwise, all frames of the sequence are included in the histogram calculation.

Mono interpretation:  This option is only relevant for color images.  If selected, luminance values are calculated from the R, G, and B channels for all pixels, and the luminance values are graphed in the histogram.  Otherwise, the R, G, and B channels are graphed separately.

Exclude Bins: Allows you to exclude the specified number of pixel values ("Bins") from the histogram display.  For example, if you enter "10," the lowest and highest 10 pixel values are not graphed in the histogram.

Auto Open/Close: Automatically opens/closes the Image Histogram when an image is activated/deactivated.

Line Profile

Initial Profile: Select one of the options in this pull-down list box to control what line profile(s), if any, are displayed when the Line Profile window is initially opened.

Save Line Profiles: If selected,Image-Pro enables the storage of Line Profiles in TIF files.  If unchecked, line profiles will not be storable across sessions.

Capture Options

General

Simulation Mode:  Enables the simulation mode in the capture module.

Reset Capture Region: Set to "On" to have Image-Pro reset the capture ROI settings to full size at startup.  Otherwise, the last-used ROI will be reapplied across sessions.
