)
- (BOOL)setOverlaySize:(LeadSize)size
forImageAtIndex:(NSInteger)index
error:(NSError **)error
index
The index of the overlay for which to set the image size. This index is zero-based and should be less than or equal to MaxOverlays.
width
New image width in pixels
height
New image height in pixels.
This method is available in the (Document/Medical only) Toolkits.
Sets the size of the overlay image for a certain index. If the image already has an overlay image at index, it will be freed and the overlay size will be set to width by height pixels. If the image has no overlay image at index, a new empty overlay image will be created with size of width and height. After calling SetOverlayImageSize, you must call UpdateOverlayBits to allocate the overlay bitmap and set the data.
