CD_WMF - Windows Metafile Driver (cdwmf.h)

+ +

This driver allows creating a Microsoft Windows Metafile, the format used + by 16-bit Windows systems to store graphics primitives. Usually, the filename + has an extension "*.wmf".

+

The driver works only in the Microsoft Windows platform, but you can use it + in other platforms without the risk of compilation error. If you attempt to + create a canvas in another platform, function + cdCreateCanvas will return NULL.

+

It is recomended to use EMF instead of WMF whenever is possible.

+ +

Use

+ +

The canvas is created by means of a call to the function + + + cdCreateCanvas(CD_WMF, Data), after which other + functions in the CD library can be called as usual. The + Data parameter string has the following format:

+ + 
"filename widthxheight [resolution]"     or in C "%s 
+    %dx%d %g"
+ +

The file's name and dimensions are required. Width + and height are provided in pixels (note the + lowercase "x" between them). Resolution is the + number of pixels per millimeter; its default value is the screen resolution.

+

Any amount of such canvases may exist simultaneously. Function + cdCreateCanvas creates a + memory-based metafile, and a call to function + + cdKillCanvas is required to + close the file properly.

+

In fact the driver uses a slightly different format, called Aldus Placeable + Metafile (APM). It attaches a small header to the beginning of the file, + allowing other applications to import better the metafile contents.

+

This + driver is NOT available for the GDI+ base driver.

+ +

Behavior of Functions

+ +

This driver is greatly platform-dependent. For further detail, see the + Behavior of Functions of the Microsoft Windows + (GDI) platform. However, it should be noted that some functions behave + differently from the basic functions of each platform.
