video.texturepage
Generic, API-independent texture page.
- struct TexturePage(TexturePacker,TextureBackend);
Texture page with customizable texture packer and API specific backend.
- TexturePacker packer_;
Texture packer, handles allocation of texture space.
- TextureBackend backend_;
Texture backend, hides graphics API details.
- Vector2u size_;
Size of the page in pixels.
- ColorFormat format_;
Color format of the page.
- this(const Vector2u size, const ColorFormat format);
Construct a GLTexturePage.
Parameters:Vector2u size Dimensions of the page in pixels. ColorFormat format Color format of the page. - bool insertTexture(ref const Image image, out Rectu pageArea);
Try to insert an image to this page and use it as a texture.
Parameters:Returns:Image image Image to insert. Rectu pageArea Area taken by the texture on the page will be returned here.
Floating-point texture coordinates can be calculated by dividing pageArea by texture page size.True on success, false on failure.- void start();
Use this page to draw textured geometry from now on.
- void removeTexture(ref const Rectu bounds);
Remove texture with specified bounds from this page.
- const pure bool empty();
Determine if this page is empty (i.e. there are no textures on it).
- const pure Vector2u size();
- const pure ColorFormat format();
- const string info();
Return a string containing information about the page.
Format of this string might change, it is used strictly for debugging purposes and not meant to be parsed.
Returns:String with information about the page.
