Public Enumeration mcImageUndoOperationFlags

Members

Member name	Value	Description
mciuofDefault	0	No flags, backupsource is the Context argument rectangle, if one is given, else it is the whole image. The Aoi is also captured as part of the backup. All frames are saved.
mciuofBackupIsWholeImage	1	Backup is of wholeimage unless a Context argument rectangle is supplied. This is the default
mciuofBackupIsAoi	2	Backup is of the Aoibounds only, unless a Context argument rectangle is supplied.
mciuofDoNotSaveTheAoi	4	If set, the Aoi isnot saved on the stack, nor will the existing Aoi be changed when an Undo or Redo is done using this Backup.
mciuofSaveActiveFrameOnly	8	If set, only theActiveFrame is saved. Otherwise either all frames or the ActiveFrameRange are saved (depending on whether the mciuofSaveActiveFrameRange flag is set).
mciuofSaveActiveFrameRange	16	If set, theActiveFrameRange is saved so long as UseActiveFrameRange is TRUE.
mciuofDoNotChangeModify	32	If set, theMcImage.Modified property is not restored across an undo. This flag may also be passed as the Operation argument for McFeatures or McGraphOverlay McUndoable objects.
mciuofStandardBackup	18	Standard backup for most operations. Backup source is the Context argument rectangle if one is given, else it is the Aoi. The ActiveFrameRange or ActiveFrame only are saved (depending on the state of UseActiveFrameRange). The Aoi is also captured as part of the backup.
mcioufForceLimitMask	12288	A mask for a 4-statevalue, one of mciuofForceXxxxxx values, that controls whether and how the normal limits on creating backed up images and whether they are created with discardable memory are determined. These values are only honored if neither the mcCommonUndoStackOperationFlags.mccusofDiscardedInfo nor mciuofSourceTooBig flags are set in the Operation argument (either of these flags being set during a Redo Backup call indicates that the undo state has already been discarded).
mciuofForceNormalLimits	0	Normal limits areapplied based backed up image size and on the McResourceManager.ImageUndoLimits properties (see mcImageUndoLimits for the various properties). This is the default.
mciuofForceDiscardable	4096	Force the created backupimage to have immediately discardable image memory should memory become tight. When value is given, then the backup image will not be created at all if it would force memory to be discarded or swapped out.
mciuofForceConditionallDiscardable	8192	Force the created backupimage to have conditionally discardable image memory. The time-out before the memory becomes discardable is set the McResourceManager.ImageUndoLimits(mciulConditionallyKeepUndoTimeoutSec) property.
mciuofForceKeep	12288	Force the createdbackup image, no matter its size, to have non-discardable image memory. Should memory become tight then this image's memory will be spooled out to a temporary swap file.
mciuofSourceHadAnAoi	65536	For internal use. Do not set.
mciuofSourceWasModified	131072	For internal use. Do not set.
mciuofSourceTooBig	262144	For internal use. Do not set.
mciuofUndoOperationActionMask	15728640	Mask for operationaction codes.
mciuofAboutToRemoveFrames	1048576	Operation actioncode: We are about to remove one or more frames via a McImage.RemoveFrames call. The Context argument holds a length-3 array giving the starting frame, the number of frames about to be removed and the total number of frames expected before removal. The image data itself (except for the frames that will be removed) are not backed up, so only the mciuofDoNotChangeModify and mcCommonUndoStackOperationFlags may be OR'ed in with this code. The Restore operation assumes that the anticipated frame operation was performed, so if it was not, you must pop the state off of the stack.
mciuofAboutToAddFrames	2097152	We are about to addone or more blank frames via McImage.AddFrames call. The Context argument holds a length-3 array giving the starting frame nsertion point (that is the current frame index before which the new frames will be inserted), the number of frames about to be inserted and the total number of frames expected before insertion. The image data itself is not backed up, so only the mciuofDoNotChangeModify and mcCommonUndoStackOperationFlags may be OR'ed in with this code. The Restore operation assumes that the anticipated frame operation was performed, so if it was not, you must pop the state off of the stack.
mciuofAboutToReorderFrames	3145728	We are about toreorder the frames with a call to the McImage.ReorderFrames method with the mciffType argument set to mcrffFrameList. The Context argument holds a copy of the McImage.ReorderFrames ReorderFrom argument that will be used. The image data itself is not backed up, so only the mciuofDoNotChangeModify and mcCommonUndoStackOperationFlags may be OR'ed in with this code. The Restore operation assumes that the anticipated frame operation was performed, so if it was not, you must pop the state off of the stack.
