Talk:Electronics/Symbols

Page http://wikibooks.org/wiki/Electronics:Symbols  contains images that are PNG files that have a lot of KB weight. Should they not have been exported as GIFs?

The policy is to use PNGs for all diagrams, and to only use GIFs for animations, partly because GIFs are currently encumbred by a patent. Carandol

PNG files actually have pretty good lossless compression. They're like bitmaps but with compression algorithms used. I don't think they have very much KB weight at all.

KB weight? as in kilobytes? look at the file sizes. they are usually less than 1 KB. not exactly huge files. - Omegatron 12:52, 10 May 2004 (UTC)

One thing that could be done is to take the text out of the image file then crush them with an png crushing utility see en:Wikipedia:How_to_keep_image_file_sizes_as_small_as_possible for details Theresa knott 13:14, 10 May 2004 (UTC)


 * I tried PNGCRUSH on a few of them and they are already about as small as possible. It could only reduce them by about 10 bytes max.  They are already really really small though.  <1KB is really good.  They are two-color images and compress very well.  I don't understand why someone is saying they are too big.  - Omegatron 15:51, 11 May 2004 (UTC)


 * Somewhat related. I modified Klunky.  See Electronics:Template for details. - Omegatron 23:46, 11 May 2004 (UTC)


 * It would probably be a good idea to have the text outside of the images, and also to have the images in separate files, for ease of editing. At least to have groupings like resistors, variable resistors, thermistors, etc. in separate files, and put the images next to each other, like Wanderer's BJT images.  Formatting is more difficult, that way, though.  I guess it would need tables... - Omegatron 21:06, 25 May 2004 (UTC)

Moved from article:

Not bad. The question is how big we want our pictures to be?

What would really be nice is to have some sort of circuit builder. That would be a great way to teach electronics, but it would probably be a lot of work.

Circuit builder of choice: mspaint.exe


 * I think we should use Klunky. I have mentioned this a million times.  It is easy, uniform, good look for the web, much much faster than mspaint, everyone can access it, etc. etc.  see Electronics:Template for more. - Omegatron 14:30, 30 Mar 2004 (UTC)

Greek Alphabet
The Greek alphabet in the article appears to be missing omikron (it's after xi).

Perhaps, instead of duplicating information, that section should link to http://en.wikipedia.org/wiki/Greek_Alphabet?
