Hi, i am converting an Image to an 1Bpp Indexed One Code:Aurigma.GraphicsMill.Bitmap theTiffImage = new Aurigma.GraphicsMill.Bitmap();
theTiffImage.Unit = Aurigma.GraphicsMill.Unit.Mm;
theTiffImage.HorizontalResolution = 300;
theTiffImage.VerticalResolution = 300;
theTiffImage.Create(80, 50, Aurigma.GraphicsMill.PixelFormat.Format32bppArgb);
... certain Images will be drawn onto theTiffImage Bitmap ... Code:theTiffFile.ColorManagement.ConvertToIndexed(1, Aurigma.GraphicsMill.ColorPaletteType.GrayScale, new Aurigma.GraphicsMill.ColorPalette(theTiffFile, theTiffFile.HasAlpha));
This lasts very long! Is there a way to fasten ist? reagards Christian Edited by user Tuesday, December 18, 2007 8:11:24 PM(UTC)

Hello Christian, If you want to convert your RGB image to bicolor indexed image, you should not create bicolor palette for image (it always has two colors: black and white :) ), it is rather time expensive operation. Your code takes 0.3 sec on my workstation. I have modified you code sample, now it takes about 0.1 sec: Code:Aurigma.GraphicsMill.Bitmap theTiffImage = new Aurigma.GraphicsMill.Bitmap();
theTiffImage.Unit = Aurigma.GraphicsMill.Unit.Mm;
theTiffImage.HorizontalResolution = 300;
theTiffImage.VerticalResolution = 300;
theTiffImage.Create(80, 50, Aurigma.GraphicsMill.PixelFormat.Format32bppArgb);
theTiffImage.ColorManagement.ConvertToIndexed(1, Aurigma.GraphicsMill.ColorPaletteType.Bicolor, null);
