imazen / libwebp-net Goto Github PK

I can losslessly encode an image without an alpha channel, but when decoding the data is misaligned.
The encoder specifies the data format, but the decoder always uses BGRA

I think the problem might be due to supplying PixelFormat32... to encoding methods that expect 24bits per pixel, because I noticed that a non-alpha compression is larger than a compression with an alpha channel.

Hi,

I realize this propably isn't your priority but using this lib on non windows systems utilizing mono fails at the moment. This is due to the fact that WebPFree is a method injected solely through the makefile for the (windows) dll version of the lib.

A good replacement would be WebPSafeFree (utils.h) which provides this function for all systems from 0.4.1 upwards.

Also providing an MSIL version of the package on NuGet (and tagging the repository with the nuget releases) would be a blast :)

can you post the updates, looks like the nuget has updated several times since

https://www.nuget.org/packages/Imazen.WebP

We can convert the output to Stream... but why not the something for input?
It is really inconvenient to have to convert the input to Bitmap.

Got this working in development fine... however when I deploy it (An Asp.Net MVC Framework app) I cannot get it to work. Worse yet it does not generate any exceptions but simply outputs an empty 0kb file! I could not install VS 2015 C++ Redistributable as I already have VS 2017 C++ Redistributable. I also put the 32 and 64 bit versions in the corresponding locations i.e. System32 and SysWow64 which worked in dev. Am I missing something else? Any help would be greatly appreciated.

Also note that I am running on Windows Server 2019 thanks.

I noticed the NuGet package is from over a year ago. What needs to happen to get it updated?

Hello,

I need to use the Imazen.WebP library inside a windows service project. Therefor it needs a strong name. Even if I manage to strong name the Imazen.WebP.dll the initialization fails with:

System.IO.FileLoadException: The File or Assembly "Imazen.WebP, Version=9.0.1.0, Culture=neutral, PublicKeyToken=null" or dependency could not be found. A strong named assembly is required. (Exception HRESULT: 0x80131044)

I think this is because the libwebp.dll is not signed / strong named. Is it possible to use the library in such context?

I use this library for WEBP image but my problem is, this library use x86 DLL all the time and it does not use x64 and because of this my solution CPU configuration is set to any CPU and I can't use all my hardware source, can any one help me?

The calling convention is defaulting to stdcall, it needs to be cdecl. This is causing stack corruption.

Google announced this today: http://blog.chromium.org/2014/03/webp-improves-while-rolling-out-across.html

Have spent some hours to see the 'unable to load libwebp.dll or one of its dependencies' when using libwebp-net from NuGet.

However the project works like a champ when I add the repo as submodule and simply add Imazen.WebP as project reference.

Hi,
Do not have information about project page (www.github.com/imazen/libwebp-net) on Nuget page (www.nuget.org/packages/Imazen.WebP)

Nothing in version 10.0.1 and 9.0.1

Is this lib anycpu (this is, does it load automatically the proper dll according to the arquitecture)?
Also, do the dlls require some specific version of visual c++ runtimes?
