Class HwmfFill.WmfDibStretchBlt

java.lang.Object

org.apache.poi.hwmf.record.HwmfFill.WmfDibStretchBlt

All Implemented Interfaces:

GenericRecord, HwmfFill.HwmfImageRecord, HwmfRecord

Direct Known Subclasses:

HwmfFill.WmfDibBitBlt

Enclosing class:

HwmfFill

public static class HwmfFill.WmfDibStretchBlt
extends Object
implements HwmfRecord, HwmfFill.HwmfImageRecord

The META_DIBSTRETCHBLT record specifies the transfer of a block of pixels in device-independent format 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_DIBSTRETCHBLT, one which specifies a device-independent bitmap (DIB) 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_DIBSTRETCHBLT. The subsections that follow specify the packet structures of the two forms of META_DIBSTRETCHBLT.

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 HwmfBitmapDib	target	A variable-sized DeviceIndependentBitmap Object that defines 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 HwmfBitmapDib target

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