Graphics Converter V1.2 for the C64 by Georg Schwarz. Graphics Converter is capable of reading and writing a variety of different graphic formats of both hires and multi color. I wrote it because I wanted a powerful and comfortable utility to archive pictures from different sources.(American users please note that not all graphic formats listed might be known to you; on the other hand formats popular in America might not be included. ) to save space I also included a compression/decompression routine. All compressed files (starting with a '0' on the disk) can be viewed with the view pictures option from the main menu. Since the program is fully menu driven (use joystick or crsr keys) it should be possible to easily use it without any further explanation.

Koala Picture Converter by Midwest Micro, Inc. (1984) - I'll be honest, I'm not excatly sure what this program is supposed to do.  I tried playing with some of the colors to do dithering, but there was no effect.  Anyway, I included the Koala picture I tested with on the disk, good luck.

Saw this program posted over at csdb.dk and had recently been looking for something just like this.  It's not a turnkey solution, but if you read through the included .ASM source code there are some docs in it that describe what you need to do.  IMHO, this program is begging for a nice user interface ;)

1989 by Benny Hill. This is definitely a rip off of the 1987 Picture Converter by Datel. If this wasn't considered LAME back in the day, I don't know what is.

From the words of the Author (Bryce L. Tomlinson):

This program was created to help convert PRG/SEQ PETSCII graphics files, such as those created with my program Kaleidoscope V4, into PRINT statements in a basic program. This is useful for program menus, intro screens, demos, etc, and was even used to make the title screen for this program.

Simply input your filename, tell it if it is a SEQ or PRG file, select your device, and away it goes. When it's done, all you'll have left is your program with your graphics included in it!
