Methods

getImageCount

getImageCount(Filename) : Integer
 

Name	Type	Default	Description
Filename	String		A file that contains an image.

If the image file contains more than one image and the image handler is capable of retrieving these individually, this function will return the number of available images. Most imagehandlers return 1.

Unlike wxWidgets this method expects a filename instead of an inputstream.

loadFile

loadFile(Image, 
         File, 
         Verbose = true, 
         Index = 0) : Boolean
 

Name	Type	Default	Description
Image	wxImage		The object that gets the loaded image.
File	String		The name of the image file.
Verbose	Boolean	true	When true the image handler will report errors using wxLog
Index	Integer	0	The index of the image in the file (zero-based).

Loads a image from a file, 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. Returns true when successful, false otherwise.

Unlike wxWidgets this method expects a filename instead of an inputstream.

saveFile

saveFile(Image, 
         Filename, 
         Verbose = true) : Boolean
 

Name	Type	Default	Description
Image	wxImage		The object that gets the loaded image.
Filename	String		Opened output stream for writing the image data.
Verbose	Boolean	true	When true the image handler will report errors using wxLog

Saves a image to a file. Returns true on success, false otherwise.
