This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.
The WebGL2RenderingContext.blitFramebuffer()
method of the WebGL 2 API transfers a block of pixels from the read framebuffer to the draw framebuffer.
Syntax
void gl.blitFramebuffer(srcX0, srcY0, srcX1, srcY1, dstX0, dstY0, dstX1, dstY1, mask, filter);
Parameters
srcX0, srcY0, srcX1, srcY1
- A
GLint
specifying the bounds of the source rectangle. dstX0, dstY0, dstX1, dstY1
- A
GLint
specifying the bounds of the destination rectangle. mask
- A
GLbitfield
specifying a bitwise OR mask indicating which buffers are to be copied. Possible values:
gl.COLOR_BUFFER_BIT
gl.DEPTH_BUFFER_BIT
gl.STENCIL_BUFFER_BIT
filter
- A
GLenum
specifying the interpolation to be applied if the image is stretched. Possible values:
gl.NEAREST
gl.LINEAR
Return value
None.
Examples
gl.blitFramebuffer(0, 0, canvas.width, canvas.height,
0, 0, canvas.width, canvas.height,
gl.COLOR_BUFFER_BIT, gl.NEAREST);
