## Classes
class | wxMetafileDC
| This is a type of device context that allows a metafile object to be created (Windows only), and has most of the characteristics of a normal wxDC. More...
class | wxMetafile
| A wxMetafile represents the MS Windows metafile object, so metafile operations have no effect in X. More...

## Functions
bool | wxMakeMetafilePlaceable (const wxString &filename, int minX, int minY, int maxX, int maxY, float scale=1.0)
| Given a filename for an existing, valid metafile (as constructed using wxMetafileDC) makes it into a placeable metafile by prepending a header containing the given bounding box. More...

## Function Documentation

## ◆ wxMakeMetafilePlaceable()

bool wxMakeMetafilePlaceable | ( | const wxString & | filename,
|  | int | minX,
|  | int | minY,
|  | int | maxX,
|  | int | maxY,
|  | float | scale = `1.0`
| ) |  |

Given a filename for an existing, valid metafile (as constructed using wxMetafileDC) makes it into a placeable metafile by prepending a header containing the given bounding box.

The bounding box may be obtained from a device context after drawing into it, using the functions wxDC::MinX(), wxDC::MinY(), wxDC::MaxX() and wxDC::MaxY().

In addition to adding the placeable metafile header, this function adds the equivalent of the following code to the start of the metafile data:

SetMapMode(dc, MM_ANISOTROPIC);
SetWindowOrg(dc, minX, minY);
SetWindowExt(dc, maxX - minX, maxY - minY);

This simulates the wxMM_TEXT mapping mode, which wxWidgets assumes.

Placeable metafiles may be imported by many Windows applications, and can be used in RTF (Rich Text Format) files.

scale allows the specification of scale for the metafile.

This function is only available under Windows.
