Description
Gets the size of an image read from a specified file.
Use GetImageSize to get the size of an image read from a file specified by the AFileName parameter.
GetImageSize returns a TPointF. TPointF.X is the width of the image and TPointF.Y is the height.
For TBitmapCodecManager, GetImageSize returns TPointF(0,0). The decoder for each different supported device overrides this method to evaluate and returns the size.
When calling GetImageSize, the method of the proper decoder will be called automatically.
