BionicWave	Posted - Jul 27 2011 : 16:55:09 Lets say you have a TImageEn Component, load it with a picture. Lets Zoom in, so that you cannot see the whole picture. How do i get to know the actual size of the bitmap in its zoomed state? The original size of the picture is 256x256 pixels. In Zoomed state it is much bigger. I need to know the exact size in zoomed mode.

This formula can only estimate the exact size: width := trunc(ImageEn.IEBitmap.Width * ImageEn.Zoom / 100); height := trunc(ImageEn.IEBitmap.Height * ImageEn.Zoom / 100); While the exact size is (which can change of 0..1 from the estimated one): width :=ImageEn.XBmp2Scr(ImageEn.IEBitmap.Width) - ImageEn.XBmp2Scr(0); height := ImageEn.YBmp2Scr(ImageEn.IEBitmap.Height) - ImageEn.YBmp2Scr(0);
