Class HwmfFill.WmfStretchDib

java.lang.Object

org.apache.poi.hwmf.record.HwmfFill.WmfStretchDib

All Implemented Interfaces:

GenericRecord, HwmfFill.HwmfImageRecord, HwmfRecord

Direct Known Subclasses:

HemfFill.EmfStretchBlt, HemfFill.EmfStretchDiBits

Enclosing class:

HwmfFill

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

The META_STRETCHDIB record specifies the transfer of color data from a block of pixels in device independent format according to a raster operation, with possible expansion or contraction. The source of the color data is a DIB, and the destination of the transfer is the current output region in the playback device context.

Field Summary

Fields

Modifier and Type	Field	Description
protected HwmfBitmapDib	bitmap	A variable-sized DeviceIndependentBitmap Object (section 2.2.2.9) that is the source of the color data.
protected HwmfFill.ColorUsage	colorUsage	A 16-bit unsigned integer that defines whether the Colors field of the DIB contains explicit RGB values or indexes into a palette.
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.

A 16-bit unsigned integer that defines whether the Colors field of the DIB contains explicit RGB values or indexes into a palette.

srcBounds

protected final Rectangle2D srcBounds

the source rectangle.

dstBounds

protected final Rectangle2D dstBounds

the destination rectangle.

bitmap

protected final HwmfBitmapDib bitmap

A variable-sized DeviceIndependentBitmap Object (section 2.2.2.9) that is the source of the color data.
