File > New
Use the New command to create a blank image of specified dimensions and class. After creating a blank image, image data can be copied into it using the Paste command.
Image Type: From this list box select the kind of image you want to create. Image Type defines the type and depth in bits per pixel (BPP) of your new image. The following image types can be selected:
|
IMAGE TYPE |
BITS PER PIXEL |
|
Gray Scale 8 |
8 BPP |
|
Gray Scale 12 |
12 BPP |
|
Gray Scale 16 |
16 BPP |
|
Floating Point |
32 BPP |
|
RGB 24 |
24 BPP (8 bits per color channel) |
|
RGB 36 |
36 BPP (12 bits per color channel) |
|
RGB 48 |
48 BPP (16 bits per color channel) |
Click on the Background Color button to select the initial color fill for the new image.
Resolution: Within this box you can specify a logical image resolution in terms of dots-per-inch (DPI). If the Units selection is set to cm, this value will be used to calculate the spatial resolution (i.e., dimensions in pixels) of your new image. For example, if you set Resolution = 100, and Width and Height = 2 cm x 2 cm, your image dimensions will be established at 200 pixels x 200 pixels. If the Units selection is set to Pixels, you may assign a logical resolution to the image, but it will not be used to determine the image's spatial resolution.
After the image is created, Resolution can be viewed and changed using the Info command. Image-Pro stores the resolution value with most file types (TIFF, for example). Image-Pro will use this information only to determine the image size for printing, however, many external programs including the Report Generator, use this resolution to scale an image when it is imported (see the Info command for more about this).
Width: Enter image width in cm, if the Unit field is set to cm, or in Pixels if the Unit field is set to Pixels. The width value establishes the number of pixels the new image window will contain in the horizontal direction.
Height: Enter image height in cm if the Unit field is set to cm, or in Pixels if the Unit field is set to Pixels. The height value establishes the number of pixels the new image window will contain in the vertical direction.
Unit: From this list box, select the terms (cm or Pixels) in which you want to express the Width and Height values. When cm is selected, the image's spatial resolution is derived by multiplying the Resolution value by the Width and Height values (e.g., if Resolution is set to 100, and Width and Height to 2" x 2", image dimensions will be established at 200 pixels x 200 pixels). When Pixels is selected, image dimensions are established directly from the Width and Height values that you enter.
Number of Frames: If you are creating a sequence of images, enter the number of frames in the new sequence. Otherwise, for single images, enter 1.
Memory: This item displays the amount of memory the image requires. Memory requirements are determined by:
Height * Width * BPP * 1/8
where Height and Width are measured in pixels.
Note: Gray Scale 12 uses 16, not 12, as BPP in the above memory requirement calculation. Although a Gray Scale 12 image uses only 12 bits per pixel, the 12 bits occupy 2 bytes (16 bits) of memory. Similarly, RGB 36 uses 48 BPP in the calculations.
Create: Click this button to create a new, empty window of the specified size and class.
