Base Interfaces

XHalfFloatBitmap
┗ XBitmap
   ┗ ::com::sun::star::uno::XInterface

Description: Specialized interface for bitmaps containing half floats as their color components. Half floats are 16 bit wide, and some high-end GPUs already have them as supported frame buffer format.

Methods' Summary
getData	Query the raw data of this bitmap. Query the raw data of this bitmap, in the format as defined by getMemoryLayout(). With the given rectangle, a subset of the whole bitmap can be queried. When querying subsets of the bitmap, the same scanline padding takes place as when the whole bitmap is requested. Note: as we currently have no 16 bit float UNO data type, the values are transported as 16 bit integers across the API (which requires casting on both sides).
setData	Set raw data of a bitmap. Set raw data of a bitmap, in the format as defined by getMemoryLayout(). With the given rectangle, a subset of the bitmap can be changed. When setting subsets of the bitmap, the same scanline padding takes place as when the whole bitmap is changed.
setPixel	Set a single pixel of the bitmap with the given color value. When setting data on volatile bitmaps, always call isValid() before, and retrieve a new memory layout via getMemoryLayout(). At least under Windows, the memory layout can change for the same bitmap, if the user e.g. switches the screen resolution. Thus, this method will throw an IllegalArgumentException, if the memory layout changed between a call to getMemoryLayout() and setData().
getPixel	Get a single pixel of the bitmap, returning its color value.
getMemoryLayout	Query the memory layout for this bitmap

Throws: VolatileContentDestroyedException if the bitmap is volatile, and the content has been destroyed by the system.
