Leo Li	71fb55f3bf	render/pixel-format: Move has_alpha into it's own array Some opaque pixel formats (nv12, p010) require per-plane bytes_per_block info. However, it doesn't make sense to store them in wlr_pixel_format_info, as they will never be useful (currently, this info is used for shm, which doesn't have a concept of multi-planar buffers.) Let's define a separate array and function for determining whether a pixel format has alpha.	12 months ago
Simon Ser	96f3f3c92e	render/pixel-format: add support for block-based formats Some formats like sub-sampled YCbCr use a block of bytes to store the color values for more than one pixel. Update our format table to be able to handle such formats.	2 years ago

Simon Ser	6e88eeadeb	render/pixel_format: import pixel_format_info_check_stride() We'll use this function from wlr_shm too. Add some assertions, use int32_t (since the wire protocol uses that, and we don't want to use 16-bit integers on exotic systems) and switch the stride check to be overflow-safe.	2 years ago
