Base Interfaces

XHalfFloatReadOnlyBitmap
(referenced interface's summary:)
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. In contrast to XHalfFloatBitmap, this interface only permits read-only access.

Description
Specialized interface for bitmaps containing half floats as their color components.

Half floats are 16 bit wide, and newer GPUs already have them as supported frame buffer format.


Methods' Summary
setData Set raw data of a bitmap. 
setPixel Set a single pixel of the bitmap with the given color value. 
Methods' Details
setData
void
setData( [in] sequence< short >  data,
[in] FloatingPointBitmapLayout  bitmapLayout,
[in] ::com::sun::star::geometry::IntegerRectangle2D  rect )
raises( ::com::sun::star::lang::IllegalArgumentException,
::com::sun::star::lang::IndexOutOfBoundsException );

Description
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
void
setPixel( [in] sequence< short >  color,
[in] FloatingPointBitmapLayout  bitmapLayout,
[in] ::com::sun::star::geometry::IntegerPoint2D  pos )
raises( ::com::sun::star::lang::IllegalArgumentException,
::com::sun::star::lang::IndexOutOfBoundsException );

Description
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().
