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

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);
