****› KOALA PAD/ATARI ARTIST PICTURE PRINTER› by TED BURGER.›› Program will be found in this› May/June 1996 OL' HACKERS Newsletter.› (Ed. It is a program worthy of a› second printing! A.P.)›› WHAT FRUSTRATION CAN DO TO YOU!› This program is a result of becoming› frustrated while printing pictures› from the Koala Pad system. The program› is written in Atari basic with many› machine language subroutines. Some of› the ML routines are my own and some of› them came from other authors. At the› moment I can't remember the sources. › If you see some of your code in here,› Thanks. The program supports several› printers, at least Epson, Gemini, NEC,› and Prowriter. To modify it for a› different printer is very simple. You› can add the printer name to the list› around line 100, add the first letter› to the check in the same area. The› lines between 800 and 900 are where› the printer is set up. Add another› 'IF' statement with the proper› graphics control characters to set up› your printer.›› OPERATION OF THE PROGRAM› The program will ask you for the› 'picture disk', picture files must end› with the '.PIC' extender. The screen› will display a list of the files on› the disk, up to 38 files. You make› your selection from the list. The› program will load the selected picture› from the disk. The picture will appear› in color at first then switch to black› and white. The bottom of the screen› will switch to text to prompt you. › Below the text block is another line› of graphics, this shows the shade of› gray assigned to each of the four› color registers. To change the gray› shade of one of the color registers,› select which one 1-4. The prompt will› change and ask which shade you want.›› WHAT THE NUMBERS MEAN› Black = 1 and white = 5. The› numbers 2,3,4 will give you different› shades of gray in order between black› and white. This will allow you to set› up the picture in shades of gray on› the display screen.›› NOTE:› If you set color 3 and 4 to the› same shade, the text will not be› visible but things will still work. › When you get the picture set up the› way you want it, a tap of the 'P' key› will send it to the printer. The› other choices you have here are:› 'M'enu will take you back to the list› of the picture files, 'V'eiw will› temporarily show you the entire› graphics screen just in case something› important is hidden by the text› block.›› WYSIWYG› This is a case of 'WHAT YOU SEE› IS WHAT YOU GET', the gray scales from› the screen will be duplicated on the› printer.› HAVE FUN, TED BURGER › ( E-N-D )››
