Can open some gif error/gif.c/ReadGIFImage/1388

[lindexi]

I try to use this to show gif in wpf. All the time it can work perfect but it cant open some gif.

I found some gif open in this code will throw the exception.

collection = new MagickImageCollection("E:\\temp\\201710.gif");

The exception is corrupt image 'E:\temp\201710.gif' @ error/gif.c/ReadGIFImage/1388

Click here to download the gif file.

You are getting that exception because your image is corrupt/incorrect. The ImageMagick library is very picky when it comes to corrupt files and an exception will be thrown when the file is corrupt.

@dlemstra Chrome and windows picture can open it. Some gif I use ScreenToGif make may cant open in MagickImageCollection

[dlemstra]

Those programs can open it because they ignore the fact that the image is invalid. ImageMagick requires the image to be correct.

@dlemstra I should find some way to fix the invalid images, and do you have any suggestion?

[dlemstra]

You can't really fix them but it might be possible to read them with Bitmap and then save it again as a valid gif file.

But as you can see, it's an animation image. If I read it as Bitmap and save it again , I will make the animation image as a static image.

@lindexi I am sorry but I don't have an idea on how you can solve this.

@dlemstra I try to rewrite gif Parser to solve it.
