Interface
wp_single_pixel_buffer_manager_v1
— global factory for single-pixel buffers
The wp_single_pixel_buffer_manager_v1 interface is a factory for single-pixel buffers.
Request
wp_single_pixel_buffer_manager_v1.destroy
— destroy the manager
Destroy the wp_single_pixel_buffer_manager_v1 object.
The child objects created via this interface are unaffected.
Request
wp_single_pixel_buffer_manager_v1.create_u32_rgba_buffer
— create a 1×1 buffer from 32-bit RGBA values
Create a single-pixel buffer from four 32-bit RGBA values.
Unless specified in another protocol extension, the RGBA values use pre-multiplied alpha.
The width and height of the buffer are 1.
The r, g, b and a arguments valid range is from UINT32_MIN (0) to UINT32_MAX (0xffffffff). These arguments should be interpreted as a percentage, i.e. - UINT32_MIN = 0% of the given color component - UINT32_MAX = 100% of the given color component
