Hi,

I'm using LEADTools Document Imaging Suite 13.0 with 8-bit grayscale tiff images (compressed with RunLength encoding). When I call LeadImage1.IsGrayscale on these images, it is returning a value of 0 (i.e. GRAY_NO), so my images end up getting handled as Color images in my code. Is this a bug or is there some function I need to call first on the image before the IsGrayscale property gets set?

Thanks,

Mark

Mark,

I tried the following LEADTOOLS 13 main OCX code on the attached image
and it returned 1, not 0. Please try the same code and image and see if you get the same result.

LEAD1.Load "c:\temp\gray8.tif", 0, 1, 1
MsgBox LEAD1.IsGrayscale
