Zoom Grafix documentation Zoom Grafix is a great utility for printing (what else?)...graphics. The following is a detailed explination.. special keys ======= ==== [esc] is used to escape from where you are back to the beginning. You may use it to stop printing, or just to get back to the picture menu. More about that later. [<-] is used to backspace.use it to change something that you've al- ready typed. In most of Zoom gr- aphix, you can back up past the current line all the way to a pre vious selection. This can be han dy in the tricky parts, like when your setting the Zoom window [->] is the opposite of the [<-] key. Its used to move ahead, and it does something else; it accepts each character on the screen that it moves over (duh.) [return] is the key that tells Zoom graphix that you're done entering (duh again) [spacebar] is used to make Zoom Grafix stop printing...if your printer has memory in it, it may take a bit longer for it to stop. the set up === === == The first time you use Zoom grafix you will be asked for printer info. This set up may be changed if you are using a different printer later on. Using the wrong set-up can't hurt your printer or computer. But the program probably won't print out the picture. If you type in a wrong answer to one of the set-up questions, you can back space with the [<-] key.using [esc] will take you back to the beginning. the picture menu === ======= ==== The picture menu lets you see the curr- ent graphics screen while letting you change the picture by flipping it,ex- changing screens, or loading a new one from a disk. If the graphics area looks like garbage don't be alarmed;it only means you dont have a picture loaded into the screen yet.if you're trying to print graphics from another program that you were run- ning before you ran zg,you might need to swap screens to see the pic. You want.press [s] to swap screens If you wish to load a picture insert you dos 3.3 disk and press [l] The flip command [f] will turn the picture upside down.this is useful in printing graphs or charts(dont ask me why though...) the main menu === ==== ==== The main menu lets you vary the print- ing of the picture in many ways. You can change any option shown on the menu by selecting its number.the curr- ent values are shown on the right on the menu,and you can decide to go ahead and print it that way - all you have to do is press [return] 1) white dots depending on the graphic you are print- ing you may want to remove the colors of the dots on the printout.most plots and graphics look best with the white dots printed black-but digitized pict- ures look better with white dots 2) printout is: this may be either upright or rotated. When Zoom Grafix prints rotated, the printout is always turned 90 degrees (i.e. Upside down).the [f] command from the picture menu toggles between these. 3) size: the size setting controls how many dots the printer prints for each dot on the screen.the smallest picture is 1 x 1, with each point on the screen printed as a single point on the printout. Guess what 2 x 2 does??? you can also mix values. 4) Zoom window this is the Zoom part of Zoom Grafix, and it lets you Zoom in,selecting what part of the screen is to be printed. The four #'s are the values of the top, bottom,left and right edges of the cur- rent Zoom window,which is shown on the picture with a flashing box.with the apple ii high-res screen,there are 192 dots from top to bottom of the screen, numbered starting with 0 at the top down to 191 at the bottom.horizontally there are 280 dots, numbered starting with 0 at the left to 279 at the far right. When the current Zoom window is less then the whole screen, you'll be given a chance to easily set it back to the full screen. Of course, if the full screen wont fit on the paper width,it will be clipped off. As you set the values the box will change.remember you can always go back and change it. 5) left margin just a way to overide the automatic centering. I wouldn't suggest fooling around with it unless nescessary. 6) print width this value is preset for the printer you are using..but can be reset if you are using wider or narrower paper. This is not the width of the paper it- self is the width of the widest line Zoom Grafix should print.Zoom Grafix will not permit setting too large. 7) delay this option will allow you to change the delay from the original set-up. This is especially important when printing dark areas. Printers with buffers need a longer time to cool,because the delay must be long enough for the buffer to empty out,also time is needed for the print head to cool. To make a delay while printing simply press the [spacebar] and press again to resume printing. 8) printer takes you to the printer/interface etc. Menu,but does not clear the picture. 9) line or form feeds does the obvious 10) intensity unless you have a shitty apple silentype dont worry about this..hmmm i wont either!(no offense to you silentype owners.) Hint ==== Insted of using a delay select to have unidirection printing which will only print from left to right..not from left to right to left...this should give the delay nescessary.
