The number of samples in the TIFF BitsPerSample entry is not supported. #2587
Description
Activity
The
Bits/Sampleis missing in these images, it should be 1.
@JimBobSquarePants How do you think we should handle this? Should we assumeBits/Sampleis 1, when its missing and compression isCCITT Group 4?tiffinfo:
=== TIFF directory 0 === TIFF Directory at offset 0x1561c (87580) Image Width: 2446 Image Length: 3453 Resolution: 300, 300 pixels/inch Compression Scheme: CCITT Group 4 Photometric Interpretation: min-is-white Rows/Strip: 1716 Planar Configuration: single image plane@brianpopow Yes, I think so. The compression format normally only used on bitonal images so that seems a sensible default.
@JimBobSquarePants ok, I will prepare a fix for that.
@kandeepandev Do we have the permission to use your sample images for unit tests?
- Ya, we can use that.

When try to load tiff images using the below code through the error "The number of samples in the TIFF BitsPerSample entry is not supported."
using (MemoryStream loadImage = new MemoryStream(byteArray))
{
image = Image.Load(loadImage);
}
So can you suggest the possible fix or work around for this issue.
