Parameters

ImageID: GdPicture image identifier.

Return Value

Can be: 1. For 1 bit per pixel image. 4. For 4 bits per pixel image. 8. For 8 bits per pixel image. 16. For 16 bits per pixel image. 24. For 24 bits per pixel image. 32. For 32 bits per pixel image. 48. For 48 bits per pixel image. 64. For 64 bits per pixel image.

Example

Removing staple marks on 1bpp b&w image.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.bmp");
 
    if ((gdpictureImaging.GetBitDepth(imageID) == 1) && gdpictureImaging.IsBitonal(imageID, 0))
    {
        gdpictureImaging.RemoveStapleMark(imageID);
        gdpictureImaging.SaveAsTIFF(imageID, "image.tif", TiffCompression.TiffCompressionCCITT4);
    }
 
    // Release used resources.
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
