If you have the Professional edition, it is possible to use your own fonts in the program.
To do this, use Tools/Import Fonts... menu option. In the opened window, choose the desired font in the list (1), you can view his appearance in the preview window (2).
Sometimes, a warning message may appear (3) if, for example, the fonts are already imported into the software or if it is not complete.
Once you have selected the font you want, press the Import Font! button to finalize the import.
You will then see the fonts imported into the list of available fonts. Imported fonts are on the top of the list and are displayed with a yellow star to distinguish them from others.
It is necessary that the fonts are installed on the system to import them. It is not possible to select a random True Type font file to import it.
