Member Data Documentation

AISlice AITile::bounds

The slice that defines the tile (a subset of the pixel map to be copied in one iteration), a rectangular area plus depth information that controls how interleaving occurs.

See Channel Interleaving.

Referenced by Init().

ai::int16 AITile::channelInterleave[kMaxChannels]

Together with the slice information, this array specifies how to change the order of bytes making up a pixel when transferring between a raster art object and the tile data.

See Channel Interleaving.

Referenced by Init().

ai::int32 AITile::colBytes

The number of bytes used to specify a single pixel.

For a raw RGB pixel, for example, it is 3.

Referenced by Init().

void* AITile::data

A pointer to the memory containing the local copy of the pixels.

Can be a generic block of memory or a platform-specific data structure. Must be allocated by the plug-in.

Referenced by Init().

ai::int32 AITile::planeBytes

When 0, the tile receives all color data for a single pixel together.

When non-zero, the tile receives all data for a color together (in a planar form). In this case, the value is the number of bytes making up a single plane. For instance if the pixel map is 80 by 80 pixels and the RGB data is in a planar form, the value is 6400.

ai::int32 AITile::rowBytes

The number of bytes in a row of pixel data.
