Windows: Write an image encoded to PNG after being loaded as JPEG messes up the image about clipboard HOT 5 OPEN

According to the doc of Write: Write writes a given buffer to the clipboard in a specified format. Write returned a receive-only channel can receive an empty struct as a signal, which indicates the clipboard has been overwritten from this write. If format t indicates an image, then the given buf assumes the image data is PNG encoded.

Euh yes, I don't understand yet what I did wrong in my code.

I decode a jpeg into an image.Image, then I re-encode it to PNG in a bytes.Buffer, and I write this buffer to the clipboard and to a file to compare.

The written file is good, but clipboard's content is screwed.

Which clipboard receiver are you using on Windows? Are you using the system built-in clipboard? (On Windows, use Shift+Win+s) I remember from Windows; it might be problematic because there is an implicit agreement between the content writer and content receiver.

I just past clipboard content inside paint.exe.
I don't use any non standard clipboard.

I think the implicit agrement is that the data is a PNG encoded data/file?

I experience the same issue, no matter what image I use, and if it's png encoded or not, the final image which I paste from the clipboard is corrupt. if I write it to file instead, the image is normal png image.
I guess that windows expects for BMP and not PNG or someting like that.
