Detailed Description

Generated macros and function to access pixels.

Generated macros to access pixel data

These function and macros are generated based on the pixel defintions in gfxprim_config.py. The get and put pixel functions are build on the top of macros to manipulate bytes and bits.

The GP_PIXEL_ADDR macros return a pointer to the first byte of the pixel in the gp_pixmap buffer. If the pixel is aligned to whole bytes, we just need to fetch/write a few bytes. Otherwise we need to compute the shift, fetch a few bytes and then mask and bit shift it.

Note about byte aligment

Unaligned access happens when instruction that works with multiple byte value gets an address that is not divideable by the size of the value. Eg. if 32 bit integer instruction gets an address that is not a multiple of 4. On intel cpus this type of access works and is supported however the C standard defines this as undefined behavior. This fails to work older ARM and most of the non intel cpus. So some more trickery must be done in order to write unaligned multibyte values. First of all we must compute offset and number of bytes to be accessed (which is cruicial for speed as we are going to read the pixel value byte by byte).

The offsets (starting with the first one e.g. pixel_size mod 8) forms subgroup in the mod 8 cyclic group. The maximal count of bits, from the start of the byte, then will be max from this subgroup + pixel_size. If this number is less or equal to 8 * N, we could write such pixel by writing N bytes.

For example the offsets of 16 BPP forms subgroup only with {0} so we only need 2 bytes to write it. As a matter of fact the 16 and 32 BPP are special cases that are always aligned together with the 8 BPP (which is aligned trivially). These three are coded as special cases which yields to faster operations in case of 16 and 32 BPP. The 24 BPP is not aligned as there are no instruction to operate 3 byte long numbers.

For second example take offsets of 20 BPP that forms subgroup {4, 0} so the max + pixel_size = 24 and indeed we fit into 3 bytes.

If pixel_size is coprime to 8, the offsets generates whole group and so the max + pixel_size = 7 + pixel_size. The 17 BPP fits into 24 bits and so 3 bytes are needed. The 19 BPP fits into 26 bits and because of that 4 bytes are needed.

Once we figure maximal number of bytes and the offset all that is to be done is to fetch first and last byte to combine it together with given pixel value and write the result back to the bitmap.
