| | ddgFrameBuffer ( unsigned short r, unsigned short c, unsigned short ch = 4) | |
| | Create an image and allocate memory. | |
| | bool | readZBuffer ( ddgCamera *c ) |
| | Copy the Z-buffer from the screen into the image. More... | |
| | bool | readFrameBuffer ( ddgCamera *c ) |
| | Copy the Frame-buffer from the screen into the image. More... | |
| | bool | readAlphaBuffer ( ddgCamera *c ) |
| | Copy the Alpha-buffer from the screen into the image. More... | |
Images can be read from .rgb and TGA files. An image can store an arbitrary 2D set of data.
| ddgFrameBuffer::ddgFrameBuffer (unsigned short ch = 4) |
Create an image but don't allocate memory.
ch is the number of channels (1-4). The t flag is true if this is an OpenGL texture which needs to be a power of 2.
| bool ddgFrameBuffer::readZBuffer (ddgCamera * c) |
Copy the Z-buffer from the screen into the image.
Allocates image to match screen size.
| bool ddgFrameBuffer::readFrameBuffer (ddgCamera * c) |
Copy the Frame-buffer from the screen into the image.
Allocates image to match screen size.
| bool ddgFrameBuffer::readAlphaBuffer (ddgCamera * c) |
Copy the Alpha-buffer from the screen into the image.
Allocates image to match screen size.
