C++ (Cpp) GLTexture::setSubImage Examples

Example #1

File: atlastexture.cpp Project: cmbruns/Doomsday-Engine

void AtlasTexture::commit(Image const &image, Vector2i const &topLeft) const
{
    GLTexture *tex = const_cast<AtlasTexture *>(this);

    if(size() == GLTexture::Size(0, 0))
    {
        // Hasn't been full-committed yet.
        tex->setUndefinedImage(totalSize(), Image::RGBA_8888);
    }

    tex->setSubImage(image, topLeft);
}

Example #2

void AtlasTexture::commit(Image const &fullImage, Rectanglei const &subregion) const
{
    GLTexture *tex = const_cast<AtlasTexture *>(this);

    if (size() == GLTexture::Size(0, 0))
    {
        // Hasn't been full-committed yet.
        tex->setUndefinedImage(totalSize(), Image::RGBA_8888);
    }

    tex->setSubImage(fullImage, subregion);
}
