Dear Sir/Madam,
I am having an error in my code if i try to get an image as Black & White colored. My file is a one page (tif) file in format : "Tiff Black White Ccitt Group4" Thanks in advance. Here is my code :
private static void convertToBlackWhite(FRDocument frDoc)
{
int pagesCount = frDoc.Pages.Count;
Bitmap[] blackWhiteImg = new Bitmap[pagesCount];
for (int i = 0; i < pagesCount; i++)
{
FRPage page = frDoc.Pages;
ImageDocument imageDoc = page.ImageDocument;
FREngine.Image image = imageDoc.BlackWhiteImage;
IntPtr hBitmap = (IntPtr)image.GetPicture(null, 0);
blackWhiteImg = System.Drawing.Image.FromHbitmap(hBitmap);//this line throws error
blackWhiteImg.SetResolution(image.XResolution, image.YResolution);
Gdi32Helper.DeleteObject(hBitmap);
}
//other codes..
}
