graphman	Posted - Oct 12 2011 : 02:51:17 Is there a way to save file to TIFF format with LZW compression and 16 bit color depth? How?

fab	Posted - Oct 12 2011 : 04:28:02 quote: ImageEnView1.LegacyBitmap := false; It tells ImageEn to use TIEBitmap instead of TBitmap. TIEBitmap can handle 16 bit per channel RGB images, while TBitmap cannot. quote: ImageEnView1.IEBitmap.PixelFormat := ie48RGB; It converts current image (8 bit per channel RGB) to 16 bit per channel RGB.
graphman	Posted - Oct 12 2011 : 03:51:26 Thanks. BUT What these strings for? // convert image to 48 bit RGB ImageEnView1.LegacyBitmap := false; ImageEnView1.IEBitmap.PixelFormat := ie48RGB;
fab	Posted - Oct 12 2011 : 03:04:59 You have to set BitsPerSample=16 and set the compression. This example converts input file to 16 bit per channel and compress it using LZW: // load input.jpg ImageEnView1.IO.LoadFromFile('input.jpg'); // convert image to 48 bit RGB ImageEnView1.LegacyBitmap := false; ImageEnView1.IEBitmap.PixelFormat := ie48RGB; // save as LZW, 16 bit per channel ImageEnView1.IO.Params.TIFF_Compression := IoTIFF_LZW; ImageEnView1.IO.Params.TIFF_PhotometInterpret := ioTIFF_RGB; ImageEnView1.IO.Params.BitsPerSample := 16; ImageEnView1.IO.Params.SamplesPerPixel := 3; ImageEnView1.IO.SaveToFile('output.tif');
