Graphics





This program is a programmer's utility as well as a lot of


fun. It enables you to make up user defined graphics


characters in a graphic and interactive way.


Together with the upper and lower case character set,


numbers and symbols, the Spectrum also allows you to


generate your own graphics characters. Each character is


made up of an eight by eight grid of dots. When the program


is run it displays on the left an enlarged version of a


graphics character. Two cursor arrows may be moved by the


use of the cursor movement keys, to point to one of the 64


pixels within the character. Pressing 1 will turn in into


a foreground pixel (white) while pressing 0 will result in


a red background element.


On the right is a display of 5x5 character positions


under which appears the lifesize version of the graphics


character that you are working on.


Pressing P will enable you to print the current character


into the display area, you will be asked for horizontal and


vertical coordinates. This is especially useful for build-


ing up larger user defined shapes by stacking several


characters together.


Pressing N will enable you to start designing a different


character. There are 21 in all, labeled A through to U but


the program uses the last 4 to draw the cursor arrows,


leaving 17, A-Q.


Pressing C will clear the display area.


Pressing S will save your user defined characters onto


tape. They may be reloaded with the command 'LOAD


"graphics"CODE' which will only load the user defined


graphics and will not upset any of the program or variables


in the computer.
