Graphics::Framebuffer Examples

Example File Descriptions

To view the documentation for these, just use "perldoc". Also note, to exit these just use CTRL-C

• dump.pl - A program that dumps important diagnostic data to a file called, "dump.log". Send this file as an email attachment along with your explanation of the issue. Note, it MUST be a file attachment, not pasted inline.

• fonts.pl - A program that just shows each system TrueType font. It is not too glamorous, but it shows Graphics::Framebuffer and Imager is working.

• primitives.pl - A simple spam method of testing all of the module's screen-specific operations.

• screensaver.pl - Not very fancy. I just blanks the screen and plasters the current time in random places.

• slideshow.pl - Pass it a specific image path and it will show all of the images in that path, including those in nested directories. Add an empty file called ".nomedia" to skip the contents of that directory.

• template.pl - Use a copy of this to create a script skeleton and base your script on this. You don't have to, but it helps to learn.

• text_mode.pl - Maybe your script crashed, and the cursor is not responding. Hit [ENTER] then blindly run this to fix the screen and restore text mode.

  Note, I highly suggest not using graphics mode while developing your code. It will still show you graphics output, but if your code crashes, you can still use the cursor.

• vector.pl - A rudimentary vector drawing language that uses source "gfb" files to draw on the screen. See "vector-usa.gfb" as an example.
