Moving Images Onscreen

You may also want to look at the picture that was included on your system disk. To do so, press the F key and, in response to the prompt at the top of the screen, "new file drive [x]" press the letter of the drive in which the Lumena system disk is found. (If you followed the suggestion at the beginning of the Tour the system disk is in drive A, so type A.) Then type P for a list of picture files on disk. There should appear on the screen one or more files with the extension ".PIX".

Add this name to the filename's menu by pressing a number from 1 to 9 and typing in the name. (Do not type the .PIX extension, as this is automatically added by Lumena.)

Then press LOAD in the DISK MENU. When the menu of filenames appears, press the name. When the prompt asks for 2 points, press in the Prompt Box (to select the same area of the screen where the picture was saved). Then press OK? in the Prompt Box.

After loading the pictures and before going on, press F. In response to the prompt, press the letter of the drive in which you were saving files (probably B). It is important to do this, so that you don't attempt to save pictures on your system disk.

Clear the screen by pressing twice with the cursor in the Prompt Box.

Press the Menu Label to call up the MAIN MENU.

Press XFORM. When the XFORM MENU appears, press MOVES.

Commands in the MOVES MENU enable you to replicate and rearrange onscreen images.

Using the Pen or Brush mode, make a small figure, say the number 5, in the lower left corner of the screen.

Then press DUP. The prompt asks for three points. For the first two, select diagonal corners so that your 5 is enclosed in a box. For the third point, which designates the screen area for duplication, put the cursor in the middle of the screen and press down on the pen.

The command will make duplicates of the 5 from its present position toward the right and top of the screen until it reaches the limit set by the third point. In this case, the duplicated image will fill the lower left quarter of the screen.

Press ROT, for Rotate. The prompt asks for two points, diagonal corners defining the image to be rotated. Select one corner and press down.

Since a rotated image must have the same number of pixels horizontally as vertically, the box that follows the cursor as you select the second corner will be approximately square. Move the pen diagonally to enlarge or reduce the size of the box. Pressing down for the second point will cause the image to rotate 90 degrees clockwise.

Leaving the rotated image onscreen, press LB (for Last Box) in the XB/LB command box.

This makes visible the last box used and activates it for the next

command. This means that whatever command you next select will not ask for 2P to define a screen area but will use the box shown.

Now press REFL-X. The image just rotated will reflect on its X axis-that is, turn upside down.

Animation

Press the Menu Label to return to the XFORM MENU, then press its Menu Label to return to MAIN.

Press ANIM. When the ANIMATION MENU comes to the screen, press CYCLE.

The CYCLE MENU lets you draw with a brush that uses a sequence of colors and allows you to animate an image.

Press MAP. The prompt asks for two colors. Choose colors that are some distance apart in the palette, say color 2 and color 10, and press down once on each color. (If your palette has two rows of colors, choose from the bottom row.) Do not include the first color in your selection.

Now press BRUSH and draw something. BRUSH in this menu uses as its paint color the sequence of colors selected under MAP. If you draw with a quick movement, you will see separate patches of the palette colors; if you draw slowly, the patches will overlap.

After drawing a few lines or figures, press Go. Lines drawn with this BRUSH appear to move as the composing colors shift to the next position on the palette. To stop the cycling, press down briefly anywhere on the tablet.

The restrictions given above on selecting colors in MAP were only for this first experiment, so you could see what the command does. Now that you have the general idea, try these commands with different MAP colors.

Lines drawn with BRUSH in the CYCLE MENU appear to move in the direction in which drawing occurred. A spiral drawn from the outside in will seem to move inward. Lines spraying out from a common point can have a fountain effect. The number of colors selected through MAP, the choice of colors, the size of BRUSH and the speed with which the line is drawn all affect the appearance of movement in the cycled line.

On-Line Documentation

Information on using any of the menu commands is always available from any menu (as well as from this manual). To call up documentation on a command, press the> on the left side of the Menu Label. When the word DOC appears in the Prompt Box, press the command for which you want information.

The information will appear on the screen, while your picture is stored in a temporary buffer. When you finish reading, return your image to the screen by pressing the ESC key or by pressing the pen anywhere on the tablet.

Exploring

You now have some experience with the techniques for using Lumena and some idea of the system's possibilities. Explore more manipulations by using other commands.
