Remarks
Scanning document of standard size often produces images of slightly different dimension. Some image processing operations, like BorderExtract, AutoCrop, AutoDeskew change size of the image.
Resize method sets of an image to one of:
- Predefined size (PageSize, PageOrientation parameters)
- Custom size (PageSize = epgsCusom, Width, Height, Unit parameters)
- Size of the image when it was open (PageSize = epgsOriginal)
Image data before resizing are:
- Placed on resized image according to ImageAlignment parameter in the center of an new image, one of the corners, or aligned with center of one of sides. NOTE: If ImageAlignment is not epiaBestFit and new image size is smaller than original some of original image information will be lost.
- Scaled to occupy maximum area of resized image (ImageAlignment = epiaBestFit)
