This has me a bit stumped... I'm trying to extract pictures from a file. So far I'm successfully retrieved the header and what I think is the colour for each pixel. Here's the description:
""" 3) The picture data format: The color information is 15 bit data stored in 16 bit. This means the most significant bit is unused. The data is stored line for line in little endian Intel format starting with top left edge to bottom right edge. This is normally called chunky format. Bit 0.. 4 blue value Bit 5.. 9 green value Bit 10..14 red value """ So I've got a list of 16-bit numbers, but how to extract RGB info from those I'm a bit lost. I thought at first I should convert the decimal (say 23294) into a binary (say 0101101011111110) into something like this: blue: 01011 green: 01011 red: 11111 But encountered two problems: First, I don't know what the best way is to do this conversion, but more importantly I don't see how every colour could possibly be represented like this. 65535 is presumably white, but converting this into chunks of 5 gives me a 31, 31, 31, a dark shade of grey. I guess I'm on the wrong track completely? I'm a bit unsure about how to treat what the guide calls 'UWORD'...
