[Bug]: [Solved] SyntaxError: not a TIFF file (header b"b'Exif\\x" not valid)

[pakresi]

What happened?

@AUTOMATIC1111 AUTOMATIC1111 said v.1.3.2 "fix postprocessing overwriting parameters"

Problem Details:

In extras tab, when you upload jpg and u are generating back png. jpg files have exif info png does not. So new version writing exif data to png files. When saving png it must pass existing exif argument After version v.1.3.0 there are tons of exif promlems in png files.

- Solution1:

use v.1.3.0

- Solution2:

if you have newer version v.1.3.0 in modules/images.py (find save_image_with_geninfo function)

change

            for k, v in (existing_pnginfo or {}).items():
                pnginfo_data.add_text(k, str(v))

lines like that (be careful about spaces)

            for k, v in (existing_pnginfo or {}).items():
                if(k.lower() == "exif") : continue
                pnginfo_data.add_text(k, str(v))

solving problem. Maybe someone fix this with a new version.

Still have problem?

• Do not use previously saved png files delete them
• Regenerate them truely using web-ui directly without exif headers

Steps to reproduce the problem

1. upload jpg file to extras tab
2. create png and save computer
3. upload png to anywhere in webui

Just a heads up I ran into the same issue, but with img2img. I fixed it by commenting out https://github.com/AUTOMATIC1111/stable-diffusion-webui/blob/master/modules/img2img.py#L51, the line that reads:

        img = ImageOps.exif_transpose(img)

The exception has been solved using this method，nice.
for k, v in (existing_pnginfo or {}).items(): if(k.lower() == "exif") : continue pnginfo_data.add_text(k, str(v))
