Constructor & Destructor Documentation

wxXPMHandler::wxXPMHandler ( )

Default constructor for wxXPMHandler.

Member Function Documentation

virtual bool wxXPMHandler::DoCanRead ( wxInputStream stream)
protectedvirtual

Called to test if this handler can read an image from the given stream.

NOTE: this function is allowed to change the current stream position since CallDoCanRead() will take care of restoring it later

Implements wxImageHandler.

virtual bool wxXPMHandler::LoadFile ( wxImage image,
wxInputStream stream,
bool  verbose = true,
int  index = -1 
)
virtual

Loads an image from a stream, putting the resulting data into image.

If the image file contains more than one image and the image handler is capable of retrieving these individually, index indicates which image to read from the stream.

Parameters
imageThe image object which is to be affected by this operation.
streamOpened input stream for reading image data.
verboseIf set to true, errors reported by the image handler will produce wxLogMessages.
indexThe index of the image in the file (starting from zero).
Returns
true if the operation succeeded, false otherwise.

wxImage::LoadFile, wxImage::SaveFile, SaveFile()

Reimplemented from wxImageHandler.

virtual bool wxXPMHandler::SaveFile ( wxImage image,
wxOutputStream stream,
bool  verbose = true 
)
virtual

Saves an image in the output stream.

Parameters
imageThe image object which is to be affected by this operation.
streamOpened output stream for writing the data.
verboseIf set to true, errors reported by the image handler will produce wxLogMessages.
Returns
true if the operation succeeded, false otherwise.
