Constructor & Destructor Documentation

◆ wxPCXHandler()

wxPCXHandler::wxPCXHandler ( )

Default constructor for wxPCXHandler.

Member Function Documentation

◆ DoCanRead()

virtual bool wxPCXHandler::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.

◆ LoadFile()

virtual bool wxPCXHandler::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

image	The image object which is to be affected by this operation.
stream	Opened input stream for reading image data.
verbose	If set to true, errors reported by the image handler will produce wxLogMessages.
index	The index of the image in the file (starting from zero).

Returns: true if the operation succeeded, false otherwise.

Reimplemented from wxImageHandler.

◆ SaveFile()

virtual bool wxPCXHandler::SaveFile	(	wxImage *	image,
		wxOutputStream &	stream,
		bool	verbose = `true`
	)
