struct IntegerBitmapLayout
Usage Restrictions
not published
Description
This structure describes the memory layout of a bitmap having integer color channels.

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

Since
OpenOffice 2.0.0

Elements' Summary
ScanLines Number of scanlines for this bitmap.  
ScanLineBytes Number of data bytes per scanline.  
ScanLineStride Byte offset between the start of two consecutive scanlines.  
PlaneStride Byte offset between the start of two consecutive planes.  
NumComponents Number of color components per pixel.  
ComponentMasks Mask values for packed bitmaps This member contains NumComponents 64 bit masks, which can be used to mask out the corresponding color component from the bitmap data. For the typical 32 bit RGBA color data, the four mask values would look like 0xFF000000, 0x00FF0000, 0x0000FF00, and 0x000000FF.  
Endianness Endianness of the pixel values. This value must be one of the Endianness constants  
Format Format type of this bitmap.  
IsPseudoColor This member determines whether the bitmap data are actually indices into a color map.  
Elements' Details
ScanLines
long ScanLines;
Description
Number of scanlines for this bitmap.
ScanLineBytes
long ScanLineBytes;
Description
Number of data bytes per scanline.
ScanLineStride
long ScanLineStride;
Description
Byte offset between the start of two consecutive scanlines.
PlaneStride
long PlaneStride;
Description
Byte offset between the start of two consecutive planes.
NumComponents
long NumComponents;
Description
Number of color components per pixel.
ComponentMasks
sequence< hyper > ComponentMasks;
Description
Mask values for packed bitmaps This member contains NumComponents 64 bit masks, which can be used to mask out the corresponding color component from the bitmap data. For the typical 32 bit RGBA color data, the four mask values would look like 0xFF000000, 0x00FF0000, 0x0000FF00, and 0x000000FF.
Endianness
byte Endianness;
Description
Endianness of the pixel values. This value must be one of the Endianness constants
Format
byte Format;
Description
Format type of this bitmap.

This value must be one of the IntegerBitmapFormat constants. The precise layout of the color channels within a bitmap pixel is further specified via the ComponentMasks member.

IsPseudoColor
boolean IsPseudoColor;
Description
This member determines whether the bitmap data are actually indices into a color map.

The member must not be true for bitmap formats of more than eight bits per pixel.
