396<p>TransformImage() is a convenience method that behaves like ResizeImage() or CropImage() but accepts scaling and/or cropping information as a region geometry specification. If the operation fails, the original image handle is left as is.</p>
397
398<p>This should only be used for single images.</p>
399
cristy44443b92015-05-05 00:06:07 +0000[diff] [blame]400<p>This function destroys what it assumes to be a single image list. If the input image is part of a larger list, all other images in that list will be simply 'lost', not destroyed.</p>
401
402<p>Also if the crop generates a list of images only the first image is resized. And finally if the crop succeeds and the resize failed, you will get a cropped image, as well as a 'false' or 'failed' report.</p>
403
404<p>This function and should probably be deprecated in favor of direct calls to CropImageToTiles() or ResizeImage(), as appropriate.</p>
