Does MyCanvas offer an option to print your family tree?
If yes, remember that most PCs offer an option to print to a pdf file and save it to disk.
If you don't see that option when choosing printers, google to find a free pdf utility that will add it to your computer.
Also, remember that there are many PDF reader applications that will let you OCR the images so that you can search for text.
