WebP test libwebp.dll

[Biterider]

Hi
I also found this definition in Gdiplusimaging.h
Trying to load a webp image using GdipLoadImageFromFile fails on my Win10 21H2.
Maybe it's too old and it only works on 22H2 or Win11...

I found two elements on the web, but no idea what could be done with this (other priorities right now):

GdipGetImageRawFormat

Code Select Expand

Gdip_GetImageRawFormat(pBitmap) {
; retrieves the pBitmap [file] format

GdipLoadImageFromFile didn't work with Windows 10 22H2

22H2 still have GdiPlus 10.0.19041.2130, not 10.0.22000

Hi Timo,

Windows 10 Version 2022 H2 is a very new release. Maybe, the future updates can solve the problem.
