The WebGLRenderingContext.getRenderbufferParameter()
method of the WebGL API returns information about the renderbuffer.
The WebGLRenderingContext.getRenderbufferParameter()
method of the WebGL API returns information about the renderbuffer.
js
getRenderbufferParameter(target, pname)
target
A GLenum
specifying the target renderbuffer object. Possible values:
gl.RENDERBUFFER
Buffer data storage for single images in a renderable internal format.
pname
A GLenum
specifying the information to query. Possible values:
gl.RENDERBUFFER_WIDTH
Returns a GLint
indicating the width of the image of the currently bound renderbuffer.
gl.RENDERBUFFER_HEIGHT
Returns a GLint
indicating the height of the image of the currently bound renderbuffer.
gl.RENDERBUFFER_INTERNAL_FORMAT
Returns a GLenum
indicating the internal format of the currently bound renderbuffer. The default is gl.RGBA4
. Possible return values:
gl.RGBA4
: 4 red bits, 4 green bits, 4 blue bits 4 alpha bits.gl.RGB565
: 5 red bits, 6 green bits, 5 blue bits.gl.RGB5_A1
: 5 red bits, 5 green bits, 5 blue bits, 1 alpha bit.gl.DEPTH_COMPONENT16
: 16 depth bits.gl.STENCIL_INDEX8
: 8 stencil bits.gl.RENDERBUFFER_GREEN_SIZE
Returns a GLint
that is the resolution size (in bits) for the green color.
gl.RENDERBUFFER_BLUE_SIZE
Returns a GLint
that is the resolution size (in bits) for the blue color.
gl.RENDERBUFFER_RED_SIZE
Returns a GLint
that is the resolution size (in bits) for the red color.
gl.RENDERBUFFER_ALPHA_SIZE
Returns a GLint
that is the resolution size (in bits) for the alpha component.
gl.RENDERBUFFER_DEPTH_SIZE
Returns a GLint
that is the resolution size (in bits) for the depth component.
gl.RENDERBUFFER_STENCIL_SIZE
Returns a GLint
that is the resolution size (in bits) for the stencil component.
When using a WebGL 2 context, the following value is available additionally:
gl.RENDERBUFFER_SAMPLES
Returns a GLint
indicating the number of samples of the image of the currently bound renderbuffer.
js
gl.getRenderbufferParameter(gl.RENDERBUFFER, gl.RENDERBUFFER_WIDTH);
