Introduction
Picture Maker is a complete graphics system for preparing diagrams, designs or simply pictures on your Acorn Electron. Each picture is built out of units which the user defines. These units may then be used repeatedly to constuct more complex units with optional rescaling, rotation, or colour change. Text of any size and orientation may also be used. Pictures can be saved to the current filing system.
Basic drawing functions include lines, solid triangles, arcs, circular sectors and shape filling. Other features include automatic cursor home position memory, an editing option, and a 'replay' program allowing you to draw a picture in one screen mode and then replay it in another. Joysticks can also be used with the keyboard to draw pictures on the screen.
Included in this pack is a 48-page booklet which takes you step-by-step through all the facilities provided.
Contents
The Picture Maker package includes four programs:
| DRAWPIC | for drawing pictures, displaying them in 2 modes, saving and loading pictures from cassette or disc |
| SHOWPIC | for displaying pictures in any of 5 modes |
