| | '''OpenGL extension ARB.copy_image |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.ARB.copy_image to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension enables efficient image data transfer between image |
| | objects (i.e. textures and renderbuffers) without the need to bind |
| | the objects or otherwise configure the rendering pipeline. |
| | |
| | This is accomplised by adding a new entry-point CopyImageSubData, |
| | which takes a named source and destination. |
| | |
| | CopyImageSubData does not perform general-purpose conversions |
| | such as scaling, resizing, blending, color-space, or format |
| | conversions. It should be considered to operate in a manner |
| | similar to a CPU memcpy, but using the GPU for the copy. |
| | |
| | CopyImageSubData supports copies between images with different |
| | internal formats, if the formats are compatible for TextureViews. |
| | |
| | CopyImageSubData also supports copying between compressed and |
| | uncompressed images if the compressed block / uncompressed texel |
| | sizes are the same. |
| | |
