Syntax

void JPXPaletteGetBitDepths(IN JPXPalette jpxPalette, OUT ASInt32 *bitDepths);

Parameters

jpxPalette
IN/OUT A JPX-encoded image object.
bitDepths
IN/OUT (Filled by the method) An array of bit depths for each component.

Exceptions

JPXPaletteGetNumComponents

Header: PERProcs.h:2905

Description

Returns the number of color components represented by the palette.

Related Methods

Syntax

ASInt32 JPXPaletteGetNumComponents(IN JPXPalette jpxPalette);

Parameters

jpxPalette
IN/OUT A JPX encoded image object.

Returns

The number of components of the JPX image represented by the palette.

JPXPaletteGetTable

Header: PERProcs.h:2922

Description

Returns the palette data as a read only non-seekable ASStm. The returned ASStm should be read with ASStmRead(). Each component entry in the palette is represented by the number of bytes needed to contain the bit depth for that component.
