The Original Chip Set (OCS) of the Commodore Amiga features a 12-bit RGB, 4,096-color palette.As the Amiga Copper programmable graphics coprocessor is capable of changing color lookup table entries on the fly during display, in practice the number of distinct colors visible on-screen may exceed static color lookup table sizes documented here.
Fragment of full-color image (left) vs Amiga HAM (right) Hold-And-Modify, [1] [2] [3] usually abbreviated as HAM, [4] is a display mode of the Amiga computer. [5] It uses a highly unusual technique to express the color of pixels, allowing many more colors to appear on screen than would otherwise be possible.
The number of color registers is a hardware limitation of pre-AGA chipsets in Amiga computers. Some contemporary games ( Fusion , [ 9 ] Defender of the Crown , [ 10 ] Agony , [ 11 ] Lotus II , [ 12 ] or Unreal [ 13 ] ) and animations ( HalfBrite Hill [ 4 ] ) use EHB mode as a hardware-assisted means to display shadows or silhouettes.
Amiga Advanced Graphics Architecture (AGA) is the third-generation Amiga graphic chipset, first used in the Amiga 4000 in 1992. Before release AGA was codenamed Pandora by Commodore International. AGA was originally called AA for Advanced Architecture in the United States. The name was later changed to AGA for the European market to reflect ...
Retargetable graphics [1] [2] (abbreviated as RTG) is a device driver API mainly used by third-party graphics hardware to interface with AmigaOS via a set of libraries. [3] The software libraries may include software tools to adjust resolution , screen colors, pointers , and screenmodes.
Amiga Chip Set. The Original Chip Set (OCS) is a chipset used in the earliest Commodore Amiga computers and defined the Amiga's graphics and sound capabilities. It was succeeded by the slightly improved Enhanced Chip Set (ECS) and the greatly improved Advanced Graphics Architecture (AGA).
The most widely used formats for vector graphics in Amiga are EPS and IFF DR2D. This originated from the fact that Amiga was the first platform that ran Ghostscript natively. IFF DR2D was the original standard for vector graphics generated by Amiga ProVector and was later adopted by other applications such as Art Expression and Professional Draw.
The A4000 is the first Amiga model to have shipped with Commodore's third-generation Amiga chipset, the 32-bit Advanced Graphics Architecture (AGA). As the name implies, AGA introduces improved graphical abilities, specifically, a palette expanded from 12-bit color depth (4,096 colors) to 24-bit (16.8 million colors) and new 64, 128, 256 and ...
