Transparency and the color black
Q: I'd like to make the background of my cel transparent. Can you explain
how to do this? I'd also like to use true black (RGB 0-0-0) in the cel. Is
this possible?
A: How you make the background of a cel transparent depends on whether
you are using 3DO Animator or the custom plug-ins.
3DO Animator
If you're saving a packed cel, you can choose any color that's not already
in the image as the background color. 3DO Animator automatically paints
all pixels of the selected background color as transparent.
For more information, see the 3DO Animator User's Guide.
Custom plug-ins
You cannot have true black and transparency if you use the 3DO CelWriter.
You can, however, use true black if you use the Coded8 CelWriter.
For more information, see the 3DO Custom Plug-Ins and CCMs.
Resizing art from 640 x 480 to 320 x 240
Q: How can I resize my art to 320 x 240 for a 3DO image?
A: You can do this in Photoshop or 3DO Animator:
-
- Photoshop: From the Image menu, select Image Size. Make sure the
Constrain Proportions box at the bottom of the dialog box is checked, then
adjust either the height or width field. This does a pretty good job
re-sampling the image, but it may require some cleanup for very intricate
or detailed images.
- 3DO Animator: When loading the image, choose Open As instead of Open
from the File menu. You have a choice of scaling or cropping the image.
