size of file
[edit]
I believe the size of the file could be significantly reduced by cloning, instead of copying, the cents scale for the reversed scale. In an experiment, I copied the small ticks into a new file, grouped the small ticks, cloned them, translated them, and saved them. This significantly reduces the size compared to copying. The ticks were not first combined into a single path, since that has a severe impact on rendering time.
- 1201 ticks: 397242 bytes
- 1201 with 1201 cloned: 397448 bytes
- 1201 with 1201 copied: 791377 bytes

- Did it. __Just plain Bill (talk) 11:31, 20 July 2008 (UTC)
- Thanks, Bill! That makes an impressive reduction in file size. Cloning a sub-scale is a good idea. I noticed you even cloned the zero-tick. :-)
- To confirm your suspicions about the efficiency of the SVG file format, I tried compressing the two versions with bzip2. I also created PNG files from each (1300x500) for comparison and with your suggestion in mind. (I realize PNG files are already compressed.)

white background layer may be needed
[edit]
This image may need a white background layer. If it is exported as a PNG file, the result has a "transparent" background which may be displayed as a grey, checked pattern that makes the image unreadable. Image viewers that exhibit this problem include "eog", "gthumb", and "display" (all available with Fedora 9). "eog" and "gthumb" can be configured to use a white background. Firefox 3.0 shows a white background. --Jtir (talk) 18:42, 20 July 2008 (UTC)
- Thanks. White bg works fine. --Jtir (talk) 18:11, 22 July 2008 (UTC)
So that's how you link to an image...
[edit]
Thanks, it needed that. __Just plain Bill (talk) 16:58, 23 July 2008 (UTC)
- <g> I was wondering when someone would notice that trick. I learned it exactly the same way! --Jtir (talk) 17:28, 23 July 2008 (UTC)
Addition of more just intervals
[edit]
I think adding the en:minor tone 10:9 would also be useful on the 5-limit series. Also the en:tritone 729/512 on the Pythgorean tuning. --Kupirijo (talk) 13:32, 19 September 2019 (UTC)
