org.apache.poi.hwmf.record.HwmfFill.WmfStretchBlt

All Implemented Interfaces:

GenericRecord, HwmfRecord

Direct Known Subclasses:

HwmfFill.WmfBitBlt

Enclosing class:

HwmfFill

public static class HwmfFill.WmfStretchBlt
extends Object
implements HwmfRecord

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.

Field Summary

Fields

Modifier and Type	Field	Description
protected Rectangle2D	dstBounds	the destination rectangle
protected HwmfTernaryRasterOp	rasterOperation	A 32-bit unsigned integer that defines how the source pixels, the current brush in the playback device context, and the destination pixels are to be combined to form the new image.
protected Rectangle2D	srcBounds	the source rectangle
protected HwmfBitmap16	target	A variable-sized Bitmap16 Object that defines source image content.

Field Detail

rasterOperation

protected HwmfTernaryRasterOp rasterOperation

A 32-bit unsigned integer that defines how the source pixels, the current brush in the playback device context, and the destination pixels are to be combined to form the new image. This code MUST be one of the values in the Ternary Raster Operation Enumeration

srcBounds

protected final Rectangle2D srcBounds

the source rectangle

dstBounds

protected final Rectangle2D dstBounds

the destination rectangle

target

protected HwmfBitmap16 target

A variable-sized Bitmap16 Object that defines source image content. This object MUST be specified, even if the raster operation does not require a source.
