• If you using a stream that you got from somewhere, make sure it’s position is 0 before giving to decoder
• This would not help if for example the image is HEIC and some of the users don’t have a HEIC codec installed.

when the problem happen, i was using URI string to automatically load the image from assembly , like ‘pack://application:,/myassembly;imagepath’,this code working so well on my mostly customer and i.but there are still has a little part of customer happen this issues.

some customer use win7 os, some are use win10 , i can’t ensure whether has installed HEIC codec , the runtime enviroment is complexity. finally i try to load the image manually and problem resolved.

maybe decoder cannot recoginzed the image format in memory.

my app setting the image in assembly as resouce, so when wpf loading the manifest stream and copy the data to decoder, wic can’t recognize the image data.

1. If you using a stream that you got from somewhere, make sure it’s position is 0 before giving to decoder
2. This would not help if for example the image is HEIC and some of the users don’t have a HEIC codec installed.
