WebA common operation that reduces the size of large 24 bit bitmaps is to convert them to indexed colour with an optimised palette, that is, a palette which best represents the colours available in the bitmap. 4 bit indexed colour This is identical to 8 bit colour except now only half a byte, 4 bits are used for the index. WebApr 11, 2024 · Bitmap (width: int, height: int, value_count: int) Stores values of a certain size in a 2D array. Bitmaps can be treated as read-only buffers. If the number of bits in a pixel is 8, 16, or 32; and the number of bytes per row is a multiple of 4, then the resulting memoryview will correspond directly with the bitmap’s contents. dallinborough https://aladinweb.com

The generic formula is: byteCount = Height * 4 * ( (Width + 3) * bytesPerPixel / 4) Instead of dealing with this yourself, I'd encourage you to save the bitmap header as well as the bitmap data. Use a MemoryStream. WebOpenGL requires that textures all have a 4-byte alignment e.g. their size is always a multiple of 4 bytes. Normally this won't be a problem since most textures have a width that is a multiple of 4 and/or use 4 bytes per pixel, but since we now only use a single byte per pixel, the texture can have any possible width.
