shackers	Posted - Feb 13 2020 : 09:30:26 I'm trying to add a bitmap object to an imageEnView with transparency. This is what I have so far: bmp.PixelFormat:=pf24bit; bmp.assign(bmpIconNote); bmp.TransparentMode:=tmAuto; bmp.saveToFile(filename); ImageEnV.setObjBitmapFromFile(hObj, fileName); ImageEnV.ObjWidth[hOBJ]:=48; ImageEnV.ObjHeight[hOBJ]:=48; I However, the image is not transparent. What do I need to do?

shackers	Posted - Feb 13 2020 : 14:43:58 Thanks Nigel. I'll move to layers and it's easy enough for me to change the bitmap to an icon.
xequte	Posted - Feb 13 2020 : 14:21:55 Hi For a TBitmap to be transparent it must be 32bit. Even then I don't know that assigning an icon to it will copy the alpha information. You are probably better to work with TIEBitmap to generate a transparent image. What is your source? If it is an icon file, you can just TIEBitmap.Read to load it with transparency. Also, if you are starting on a new project, you should use TIELayers, not TImageEnVect objects, e.g. ImageEnView1.LayersAdd( 'C:\myicon.ico' ); See: https://www.imageen.com/help/TImageEnVect%20vs%20TIELayers.html Nigel Xequte Software www.imageen.com
