Function Reference

Page 796 of 874

mfClipView

If set, the metafile is drawn into a clipping rectangle in the size of the metafile

or currently defined view. This flag should always be set if a user defined

view is used. See InsertMetafileExt() for further information.

mfCurrComprFilter

If set, the currently active compression filter is used to compress the image

(see SetCompressionFilter()). This flag is used only if the file is rastered to an

image.

mfDebug

If set, the EMF record names are printed to the content stream which

produces a specific output. Open the PDF file in a good text editor such as

Textpad to view the output. The PDF file must not be compressed if this flag

is used, otherwise you can't see the debug strings. Compression can be

disabled with the function SetCompressionLevel().

mfDefault

This is the default behaviour. No specific parameters are used for metafile

conversion.

mfDefBkModeTransp

If set, the initial background mode is set to transparent. SetBkMode records

still override this state. The default background mode is opaque in the GDI.

This state causes that a rectangle is printed in background of any text string,

also if the rectangle is not required. Especially if text strings are printed as

single characters the opaque background can drastically increase the

resulting file size due to the many rectangles. This flag should always be set if

the EMF or WMF files do not initialize the background mode to the required

value.

mfDisableRasterEMF

If set, EMF files are no longer rastered to an image if the file uses ROP codes

which combine background and foregound colors. Many EMF files use such

ROP codes but it is often not required to raster the EMF file because many

ROP codes which combine background and foreground colors have no effect

if no other object was drawn in background.

mfDontSkipROP_DPa

If set, the ROP code 0x00A000C9 (DPa) is considered in BitBlt, StretchBlt,

TranparentBlt, and AlphaBlend records. This kind of ROP code combines a

pattern brush with the backdrop. If the flag mfDisableRasterEMF is absent,

the usage of such a ROP code causes that the file is rendered to an image.

mfFullScale

If set, all coordinates are scaled to the output window size. Set this flag if the

EMF file uses 32 bit coordinates, e.g. large CAD drawings. Full scaling avoids

floating point overflows in PDF viewer applications because all coordinate

transformations are already applied. The resulting file size is also smaller due

to the smaller coordinate values which must be stored in the PDF file.
