    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.tif", true);
 
    // Dilates black pixels in 8 directions: E, NE, SE, S, SW, W, NW, N.
    gdpictureImaging.FxBitonalDilate8(imageID);
    gdpictureImaging.SaveAsTIFF(imageID, "image.tif", TiffCompression.TiffCompressionCCITT4);
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}

Example

Dilating a black and white tiff image. using (GdPictureImaging gdpictureImaging = new GdPictureImaging()) { // LoadInMemory parameter is set to true in order to be able to update the input file. int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.tif", true); // Dilates black pixels in 8 directions: E, NE, SE, S, SW, W, NW, N. gdpictureImaging.FxBitonalDilate8(imageID); gdpictureImaging.SaveAsTIFF(imageID, "image.tif", TiffCompression.TiffCompressionCCITT4); gdpictureImaging.ReleaseGdPictureImage(imageID); }
