Invalidating Texture data

[barotto]

I have a window where there's a bunch of <img> elements inside a <div>, each with their src property pointing to a png file on the file system via and absolute path.

These png's will be updated externally and what I'm doing now to update the content of the <div> is calling SetInnerRML("") on it and rebuilding all the <img>'s.

For some of these png's the absolute file system path won't change, but their pixel data will. Unfortunately RmlUi won't request a RenderInterface::LoadTexture() again for an image that has been already loaded, so even if I rebuild an <img> its content will remain unchanged.

How can I tell RmlUi to invalidate the state of textures associated to <img> elements?

This can be achieved by simply calling Rml::ReleaseTextures(). This way RmlUi will call LoadTexture again on all the textures.

RmlUi/Include/RmlUi/Core/Core.h

Line 153 in 7ef8ab9

RMLUICORE_API void ReleaseTextures(RenderInterface* render_interface = nullptr);

So it's all or nothing? Bummer.

I'll peruse RmlUi's source and see if I can implement something for my use case, maybe a ReleaseTexture(const String& source) or something.

Thanks.

No problem! I wouldn't mind a PR adding that functionality.
