bitplanes การใช้

• This required the use of four bitplanes at 70 ns per pixel.
• The bitplanes appear first from 1 to n, followed by the mask plane.
• The standard ordering for the bitplanes will put the least significant bit of the red component first:
• The colour map will have no more than 32 entries, but the image will have 6 bitplanes.
• These so-called'deep images'files have no CMAP chunk and usually have 24 or 32 bitplanes.
• The low order depth number of bits in planePick, planeOnOff, and planeMask correspond one-to-one with destination bitplanes.
• In HAM8 format the colour map will have up to 64 entries but the image will have 8 ( or possibly 7 bitplanes ).
• In HAM6 format the colour map will have up to 16 entries, but the image will have 6 ( or possibly 5 bitplanes ).
• In ILBM files the "'BODY "'chunk stores the actual image data as interleaved bitplanes ( and optional mask ) by row.
• :: : : : Wait, are you using the bitplanes separately ? ( I thought it was probably not the problem, but maybe it could be?
• The MC68000 processor, the blitter needs no memory cycles for fetching instructions, no silicon for decoding, and contains a barrel shifter to assist shifting pixel-accurate graphics in bitplanes.
• As illustrated in the image above, the early bitplanes, particularly the first, may have constant runs of bits, and thus can be efficiently encoded by run-length encoding.
• In dual-playfield mode, instead of acting as a single screen, two " playfields " of eight colors each ( three bitplanes each ) are drawn on top of each other.
• Alternatively, create a colour map with 64 entries, and copy the lower 32 entries into the upper half, converting them to half brightness; then use all 6 bitplanes as a colour index.
• The HAM-E technique exploited the fact that a high resolution image with four bitplanes delivers a third more memory bandwidth, and therefore a third more data, than a low resolution image with six bitplanes.
• The HAM-E technique exploited the fact that a high resolution image with four bitplanes delivers a third more memory bandwidth, and therefore a third more data, than a low resolution image with six bitplanes.
• Other improvements were the ability of the blitter to copy regions larger than 1024 & times; 1024 pixels in one operation and the ability to display sprites in border regions ( outside of any display window where bitplanes are shown ).
• The Amiga stored framebuffers in separate'bitplanes'( e . g . a series of 5 1bit images combining to produce a 32-colour display ), which made masking very convenient, as masks needed only one bitplane.
• Then each pair of pixels was encoded with information for the HAM-E unit, which converted the information into one 140 ns pixel ( generating an image 320 pixels wide, or 360 with overscan, at a color depth of eight bitplanes ).
• I was wondering if you were reading it as 5 bitplanes, or in 5 bit chunks, but I think if you were doing it the wrong way the image would look like a real mess instead of what you have .-Rainwarrior 18 : 05, 14 November 2006 ( UTC)
