Advice for posting schematics

[emerth]

I do not know what is the correct forums for this, so here I am.

I have seen, here and elsewhere, schematics posted as JPEG (jpg) files.

JPEG tends to blur pixels together. JPEG was designed to work well for photographic material - pics of people, of landscapes, of stuff that the mind's eye can fill in the fine points. This makes it difficult sometimes to distinguish "10nF" from "10mF" on highly compressed JPEG schematics.

Better for schematics are GIF and PNG files, because they do not blur pixels together: GIF & PNG tend to produce more readable technical drawings, including schematics.

I agree 100%.

If the image editor program asks questions about quality of the picture, adjust it to maximum, because usually the file will not be too big.

I use irfanview.
It allows export in many file types/compressions.

I usually never remember which compression suits different types. So I usually export the same pic to the desktop, in 4 or 5 versions. Throw away the enormous files. Look at the smaller files and select the compression type that gives good legibility.

Then go to advanced - manage attachments - browse to DESKTOP - upload - close

Can Irfanview do pdf?
