Your webp file is invalid and checks have been added that will cause this error message. For your sher3.webp
file I already made a patch earlier that would make it possible to read that incorrect file. And I just pushed a patch to make it possible to also read sher3l.webp
. This will be resolved in the next release.
Magick.NET version
magick.net-q16-x86.9.0.0.nupkg, magick.net-q16-x86.12.2.1.nupkg, magick.net-q8-x86.13.5.0.nupkg, magick.net-q16-x86.13.5.0.nupkg
Environment (Operating system, version and so on)
Windows 10, 32bit
Description
I try to use Magick.Net with this code (from stackoverflow)
using (var magickImages = new MagickImageCollection(filePath)) // Exception in this line { if (magickImages.Count > 1) { string newFilePath = FileHelpers.GenerateNewFilePath(Path.ChangeExtension(filePath, ".gif")); using (FileStream fs = new FileStream(newFilePath, FileMode.Create)) { magickImages.Write(fs, MagickFormat.Gif); } } else { string newFilePath = FileHelpers.GenerateNewFilePath(Path.ChangeExtension(filePath, ".png")); using (FileStream fs = new FileStream(newFilePath, FileMode.Create)) { magickImages.Write(fs, MagickFormat.Png); } } }
and got Exception when opening file for both sample files with message
insufficient image data in file
sher3.webp' @ error/webp.c/ReadWEBPImage/563 insufficient image data in file
sher3l.webp' @ error/webp.c/ReadWEBPImage/563 images.zipSteps to Reproduce
To reproduce use above code with attached images.zip.
I try following Magick.Net nuget packages (with correspondent dependencies):
magick.net-q16-x86.6.8.9.501.nupkg magick.net-q16-x86.9.0.0.nupkg magick.net-q16-x86.12.2.1.nupkg magick.net-q8-x86.13.5.0.nupkg magick.net-q16-x86.13.5.0.nupkg
and only v.6.8.9.501 open both files successfully, all other - fail with above messages.
I try to use ImageMagick command tool (ImageMagick-7.1.1-27-Q16-x86-dll.exe) and file 'sher3.webp' success and for 'sher3l.webp' got this:
magick convert sher3l.webp sher3l.png convert: insufficient image data in file
sher3l.webp' @ error/webp.c/ReadWEBPImage/580. convert: no images defined
sher3l.png' @ error/convert.c/ConvertImageCommand/3362.Both sample files in XnView or other free viewer/converter opens fine and converts fine.
I find in issue list that similar exception message exists for jpg and png files (I think it is already fixed).
