Class HwmfFill.WmfStretchBlt
java.lang.Object
org.apache.poi.hwmf.record.HwmfFill.WmfStretchBlt
- All Implemented Interfaces:
HwmfRecord
- Enclosing class:
HwmfFill
The META_STRETCHBLT record specifies the transfer of a block of pixels according to a raster
operation, with possible expansion or contraction.
The destination of the transfer is the current output region in the playback device context.
There are two forms of META_STRETCHBLT, one which specifies a bitmap as the source, and the other
which uses the playback device context as the source. Definitions follow for the fields that are the
same in the two forms of META_STRETCHBLT are defined below. The subsections that follow specify
the packet structures of the two forms of META_STRETCHBLT.
The expansion or contraction is performed according to the stretching mode currently set in the
playback device context, which MUST be a value from the StretchMode.
