[sdiy] How do I....... ?

[Theo]

IMHO this little rule is a good one.
If its a vector drawing use a postscript variant (EPS or PDF or...)
If its a bitmap with few colors =<16 use GIF
If its a bit map with more colors use JPEG

TIFF only makes sense for hires photo images that need to be lossless,
usually this kind of TIFFs are RGB or worse CMYK bitmaps.
Big bulky and completely useless for schematics.
Some scanners give out uncompressed B/W or color TIFF, _please_ convert them
to a more appropriate format (gif/jpeg).
Also, including a bitmap TIFF into a PDF does just that; includes.
You end up with a big ugly bitmap in a postscript envelope.
Same holds for including gif or jpeg.

Me 2 cnts,
Theo
