Convert wmf to 1bpp monochrome bitmap

Post by Ken71 » Wed Mar 15, 2017 9:44 pm

Using this code, I'm trying to convert the attached wmf to a 1bpp monochrome bitmap. In the wmf you'll see blue and red color. These colors do not show up in the bmp. What is the proper way to convert the wmf? I know the attached file is a png since I couldn't upload the wmf.

Code: Select all

Using oGdPictureImaging As New GdPicture11.GdPictureImaging
            Dim Image As Integer = oGdPictureImaging.CreateGdPictureImageFromFile(WMFFilename)
            'oGdPictureImaging.FxBlackNWhiteT(Image, 128)
            oGdPictureImaging.FxBlackNWhite(Image, GdPicture11.BitonalReduction.Stucki)
            oGdPictureImaging.ConvertTo1BppAT(Image)
            oGdPictureImaging.SaveAsBMP(Image, BMPFilename)
            oGdPictureImaging.ReleaseGdPictureImage(Image)
        End Using

Hello,

Can you please attach the original WMF file to this thread instead of the PNG version?

I placed it in a zip file and attached.

Thank you but this is not a WMF file, it is a 32-bit ARGB TIFF file with LZW compression that has been renamed.
I have no issue whatsoever to convert it to black and white with the latest release, what version of the toolkit are you using?

I had no idea it was a renamed file. Interesting. I am using version 11.2.0.10. Is the code block I provided above the correct approach to convert the file?

Yes, this is correct. You might want to update your SDK to the latest release available for this branch (11.2.39).
Here is a link to download it: https://orpalis.wimi.pro/download.php?c ... b10097b2f6
