Member Data Documentation

ai::int16 AIRasterRecord::bitsPerPixel

The number of bits used to define each pixel in the pixel map.

Valid values depend on the color space: Gray: 1 (black and white) or 8 (gray) RGB: 24 (8 bits for each color) or 48 (16 bits for each color) CMYK: 32 (8 bits for each color)

AIRect AIRasterRecord::bounds

The width and height of the image data in pixels.

The top left value of the bounds must be zero. The right value gives the width and the bottom value the height. (The coordinate system for a raster object is inverted on the vertical axis with respect to the Illustrator artboard coordinate system.)

Referenced by AIRasterRecord().

ai::int32 AIRasterRecord::byteWidth

The number of bytes in a single row of pixel data.

Not needed for AIRasterSuite::SetRasterInfo(). 1-bit data is packed so that there are 8 pixels per byte.

• If bitsPerPixel is 1 (for a black-and-white bitmap), the value is: rasterRecord.bounds.right / 8 + 1
• For all other bitsPerPixel values, the value is: rasterRecord.bounds.right * (rasterRecord.bitsPerPixel / 8)

ai::int16 AIRasterRecord::colorSpace

The color model of the pixel data, which can include an alpha channel, an AIRasterColorSpace constant.

ai::uint16 AIRasterRecord::flags

Flags defining additional options for the image.

A logical OR of AIRasterFlags.

ai::int16 AIRasterRecord::originalColorSpace

For an image that has been converted from one color space to another, the original color space, an AIRasterColorSpace constant.

If the image has not been converted, the value is -1.
