Crash when loading a 4 channel image when channel option is forced to 3 in StbImage.read_file about stb_image HOT 6 CLOSED

Hi @ChristopheBelpaire, thanks for reporting this issue. I'll try to fix this issue sometime this week!

from stb_image.

Ok, the problem comes from the way I'm loading the images StbImage.read_file(path, channels: 3)
Some of my images seems to have 4 channels, the crash seems to be caused by the fact the load is forced to 3 channel for a 4 channel image.

$ file /Users/cocoa/Downloads/archive/PetImages/Cat/10404.jpg
/Users/cocoa/Downloads/archive/PetImages/Cat/10404.jpg: Adobe Photoshop Image, 432 x 363, RGB, 3x 8-bit channels

I found one in the dataset that can cause this issue, but it's definitely not a JPEG image and seems to have wrong metadata perhaps. I'll look into this further

Awesome, thanks!

I removed the "bad" images with :

    |> Stream.filter(fn
       {:ok, {%StbImage{shape: {_, _, 3}}, _}} -> true
       _ -> false end)

To filter the channel, everything can be loaded with this filter.

Hi @ChristopheBelpaire, v0.6.6 is out and should fix this issue!

from stb_image.

Awesome!
I tried my scenario again and it seems to load all the images.
Thanks for the fix!
