557480 - (tex-image-source) MathML Torture Test: regenerate images of Tex rendering and add TeX source as alt text

Status: RESOLVED FIXED

(Core :: MathML, defect)

Description

[Frédéric Wang (:fredw)]

The images of the torture test are currently gif images with indexed colors and without transparency. This gives a poor quality. I suggest regenerating them in png (a W3C standard BTW), getting rid of aliasing and using a transparent background. To to this, the expected method is to guess the original TeX source. This will also enable us to use this source as an alt text.

The new images are now available on the page
https://developer.mozilla.org/en/Mozilla_MathML_Project/TortureTest

The TeX sources are from The TeXbook, and hence are probably protected by copyright. However, we can give the references as alt text:

1 (TeXbook, 16.2-16.3)
2 (TeXbook, 16.2-16.3)
3 (TeXbook, 17-17.1)
4 (TeXbook, 17-17.1)
5 (TeXbook, 17-17.1)
6 (TeXbook, 17.5-17.6)
7 (TeXbook, 17.5-17.6)
8 (TeXbook, 17.5-17.6)
9 (TeXbook, 17.7)
10 (TeXbook, 17.7-17.8)
11 (TeXbook, 16.2-16.3)
12 (TeXbook, 17.8)
13 (TeXbook, 17.9-17.10)
14 (TeXbook, 17.10)
15 (TeXbook, 16.2-16.3)
16 (TeXbook, 18.10-18.11)
17 (TeXbook, 18.12-18.13)
18 (TeXbook, 18.23)
19 (TeXbook, 18.23-18.24)
20 (TeXbook, 16.2-16.3)
21 (TeXbook, 18.40)
22 (TeXbook, 18.41)
23 (TeXbook, 18.42)
24 (TeXbook, 18.43)
25 (TeXbook, 16.2-16.3)
26 (TeXbook, 16.4-16.5)
27 (TeXbook, 16.4-16.5)

Once the new images are used, we can remove them from mozilla.org (mathml/screenshots/)

This patch fixes this bug. The images mathml/screenshots/ex*.gif can be removed.

Add alt text and use png images

Nice images, thanks!

Comment 5

[Frédéric Wang (:fredw)]

Thanks for all the reviews, Karl. Do you think it would be possible to take the patches for mozilla.org/projects/mathml now, or does the code freeze also apply to the website repository?

The code freeze is just for mozilla-central, and only for files that are "part of the build".  Tests, for example, can still be added without approval.

OK, thank you for the update. So I guess it is also possible to push the two rubber-stamped perl scripts of bug 534970 now?

Yes, possible, though mozilla-central tends to be busy and each push consumes resources, effectively slowing other pushes.  So I won't push them until I have some other changes that can land.
