MANIPULATING IMAGES

You can reduce the file size of an image by either reducing the color depth or by changing the resolution. Most paint programs will allow you to do either or both.

REDUCING COLOR DEPTH

Reduces the number of pens used to produce the image. Each color in the image uses a different pen, so you are reducing the number of colors that will be displayed in the picture. If you reduce the color depth of your image, you will probably want to use a color-matching routine known as dithering.

CHANGING THE RESOLUTION

Scaling (or resizing) allows you to change (either increase or decrease) the number of pixels used to display the image. To avoid distortion of the image, remember to select "keep the aspect ratio". This will keep the relative height and width of the image constant.

BUILDING AN IMAGE LIBRARY

There are many ways to build an image library. You can:

purchase libraries.

Disks and CD-ROMs loaded with graphics are readily available. Although they are often priced quite reasonably individually, the collective cost of your library can be considerable - especially if you only infrequently use only one or two of the images.

create your own custom images.

This requires some time and skill, but you can produce exactly what you want. You will need a paint program.

copy someone else's custom images.

Much of what is out there on the web is free for the taking. Watch out, however, for copyrighted material - some companies can get quite nasty! Many other companies and individuals make some or all of their material available as freeware or shareware.

Bullets, Stamps, Bars, and more.

scan images.

You will need access to a good, preferably color, scanner. You will also need a paint program to clean up the inevitable errors that creep in when scanning.
