Detailed Description

This structure describes the memory layout of a bitmap having floating point color channels.

This structure collects all necessary information to describe the memory layout of a bitmap having floating point color channels

Since

OOo 2.0

Member Data Documentation

ColorSpace

XColorSpace ColorSpace

Color space the bitmap colors shall be interpreted within.

Endianness

byte Endianness

Endianness of the pixel values.

This value must be one of the Endianness constants

Format

byte Format

Format type of this bitmap.

This value must be one of the FloatingPointBitmapFormat constants.

NumComponents

long NumComponents

Number of color components per pixel.

This value must not be negative

PlaneStride

long PlaneStride

Byte offset between the start of two consecutive planes.

This value is permitted to be negative. If this value is zero, the bitmap is assumed to be in chunky format, otherwise it is assumed to be planar. The difference between chunky and planar layout lies in the way how color channels are interleaved. For a chunky format, all channel data for a single pixel lies consecutively in memory. For a planar layout, the first channel of all pixel is stored consecutive, followed by the second channel, and so forth.

ScanLineBytes

long ScanLineBytes

Number of data bytes per scanline.

This value must not be negative

ScanLines

long ScanLines

Number of scanlines for this bitmap.

This value must not be negative

ScanLineStride

long ScanLineStride

Byte offset between the start of two consecutive scanlines.

This value is permitted to be negative, denoting a bitmap whose content is flipped at the x axis.
