Example

Removing lines from 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);
 
    // Remove vertical and horizontal lines using default parameters.
    gdpictureImaging.RemoveLines(imageID, LineRemoveOrientation.Horizontal | LineRemoveOrientation.Vertical);
    gdpictureImaging.SaveAsTIFF(imageID, "image.tif", TiffCompression.TiffCompressionCCITT4);
    gdpictureImaging.ReleaseGdPictureImage(imageID);
