The disableiOES() method of the OES_draw_buffers_indexed WebGL extension enables blending for a particular draw buffer.

Syntax

disableiOES(target, index)

Parameters

• target
  • : Must be gl.BLEND.
• index
  • : An integer i specifying the draw buffer associated with the constant gl.DRAW_BUFFERi, see WebGL draw buffer constants.

Return value

None (undefined).

Exceptions

• If target is not gl.BLEND, a gl.INVALID_ENUM error is thrown.
• If index is not a valid value, a gl.INVALID_VALUE error is thrown.

Examples

const ext = gl.getExtension("OES_draw_buffers_indexed");

ext.disableiOES(gl.BLEND, 0);
ext.disableiOES(gl.BLEND, 1);
