Hints from Messrs. Adam, Banyai, Katulka and Troeger

The best way to invert the metal image in a Unix LEdit environment:

A. In Ledit, make sure you are using a solid color for your metal. Go

to your final image, hide all other layers, and then convert the metal to

black:

1. Select the layer that you are using for metal in the Layer Menu. Its

name should now appear in the top of the Layer Menu (at the upper

left-hand corner of the Ledit screen).

2. Click "File"->"Page Setup". A menu should appear with the line "Layer

Selected: (metalname)" in the middle. Below that there is a box with

several passes; each pass had a (% of white) sub-box.

3. Write these (% of white) values down so you can revert to them later,

and then change them all to 0.

B. Print it to a file using Ledit ("File"->"Print/Plot" and enter the

filename and filetype you want).

C. Use X-View to open the file, invert it and print it.

1. at a Unix prompt, type "xv" followed by one space and then the filename

you just saved.

2. XView will open, with what should be a black and white image, if you

did everything right so far.

3. right-click and the control menu will appear.

4. Click the "24/8 Bit" button at the top of the control menu and select

"8-bit mode". This makes things faster and doesn't lose any image data.

5. Click on the "Windows" button and select "Color Editor".

6. Click the "RevVid" button. The image shown in the XV image window will

invert.

7. Click the "Close" button. The color editor menu will close.

8. You can now print the inverted image from the XV control menu:

9. Click "Print".

10. Type in the Unix printername as specified, and click "B/W".

11. Click "Max". This will resize the image to fit the current paper

setup and give you an idea how to best orient the image.

12. Choose the proper orientation (Portrait or Landscape).

13. Paper size should already be set to 8.5x11 (change if using different

paper).

14. If you changed the orientation, click "Max" again. The computer will

resize the image to better fit, but it will still leave a margin.

15. You may reduce the margins by increasing the width or height arrows.

Click the "Center" button after each change to recenter the image and

make sure that it still fits.

16. Repeat steps 14 and 15 until you are satisfied with the image layout,

and then click "Ok". This will print the image and you are done.
