WebP v0.5.0 build 2025-08-10 beta

[UEZ]

Made major updates to the DLL and UDF and fixed (probably added new) bugs. All examples changed to new DLL / UDF.

Old scripts may fail when you use DLL v0.4.3+ as function parameters changed.

Added the function to convert APNG to AWEBP.

@UEZ Hi
I was thinking at a way to keep all examples unchanged when you increase the Dll version. For example, after the last update, this is what we find in nearly each example script (there are 16 examples actually) :

If WebP_Ver2() < "0.4.4" Then Exit MsgBox($MB_ICONERROR, "ERROR", "DLL Version v0.4.4+ required!", 30)

Which means that when you'll increase the Dll version, you'll have to modify again all the examples (because the constant "0.4.4" is found in each example script)

My idea is to place the constant "0.4.4" in a single place, for example inside the function WebP_Ver2() found in WebP.au3

Actually this is the content of WebP_Ver2()

Func WebP_Ver2($sPath2DLL = "")
    Local $sDLL = Path2DLL($sPath2DLL)
    If Not FileExists($sDLL) Then Return SetError(1, 0, 0) ;DLL not found
    Return DllCall($sDLL, "str", "Web_DLL_Version2")[0]
EndFunc   ;==>WebP_Ver2

It could be modified like this :

Func WebP_Ver2($sPath2DLL = "")
    Local $sDLL = Path2DLL($sPath2DLL)
    If Not FileExists($sDLL) Then Return SetError(1, 0, 0) ;DLL not found
    Local $sDLLversion = DllCall($sDLL, "str", "Web_DLL_Version2")[0]
    If $sDLLversion < "0.4.4" Then ... ; UEZ will choose what to do here and what to return 
    ...
EndFunc   ;==>WebP_Ver2

So you got the idea. The final goal should be to leave all examples untouched when the Dll version increases, which means no more "0.4.4" constant in any example script. Each new version number of the Dll will be indicated only inside the function WebP_Ver2() , then you'll have less work to do while upgrading the Dll (and the user won't have to re-download the examples)

Do you think it's doable ?
Thanks

@pixelsearch let me think tomorrow about it.

 

I changed a lot of internal functions from str to wstr to support unicode filenames and all examples must be touched otherwise crash.

 

Currently I'm writing on an example in Freebasic (WebP Encoder GUI) how to use the DLL. Freebasic WebP DLL source code (my written DLL stuff, Google WebP dll will be linked as static library to my DLL) and other stuff can be found on my OneDrive, if you want to have a look under the hood.
