blitFramebuffer(srcX0, srcY0, srcX1, srcY1, dstX0, dstY0, dstX1, dstY1, mask, filter)
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
None (undefined
).
