yogiyang	Posted - Dec 03 2020 : 06:41:33 Hello, I don't know as to how to explain this but... I have a need to save a JPEG file in which its thumbnail is different then its actual image. Meaning the thumbnail as shown in Windows explorer and IEMView would be different then the actual image. Is this possible? If yes then how? TIA Yogi Yang

xequte	Posted - Dec 04 2020 : 19:23:06 Hi Yogi You cannot change the thumbnail that Windows Explorer shows. It will always show the content of the image (OK, this is not 100% true, but true for all practial purposes). You can make TImageEnMView show a different thumbnail that the image content, either by: - Enabling TImageEnMView.EnableLoadEXIFThumbnails and setting a different EXIF bitmap (JPEG, TIFF, only) https://www.imageen.com/help/TImageEnMView.EnableLoadEXIFThumbnails.html https://www.imageen.com/help/TIOParams.EXIF_Bitmap.html - Override the drawing of the thumbnail, e.g. in the OnImageDraw event https://www.imageen.com/help/TImageEnMView.OnImageDraw.html Nigel Xequte Software www.imageen.com
