Graphics Lab/Illustration workshop

The Graphics Lab is a project to improve the graphical content of the Wikimedia projects. Requests for image improvements can be added to the workshop pages: Illustrations, Photographs and Maps. For questions or suggestions one can use the talk pages: Talk:Graphics Lab, Talk:Illustrations, Talk:Photographs and Talk:Maps.
This specific page is the discussion page for the Illustration workshop. Any comments or questions about this specific workshop may be made here. Note that requests for image improvement, etc. do not belong here but should go on the main requests page

This is the talk page for discussing improvements to the Graphics Lab/Illustration workshop page.

A tool to monitor and improve images in Wikiprojects

Hi there! I've been a wikigrpahist for some months now. I thought about a tool to find needed images in a Wikiproject and also to find low resolution images needing improvements.

I called it Visual Content Assessment Tool, or simply VCAT.

A working version of VCAT can be found at VCAT-dashboard, you can try it using one of the samples of data I already extracted, or you can extract data for any Wikiproject using the extraction tool, a command line tool I created for this purpose.

Some of the actions you can do with this tool are:

Monitoring the visual content coverage in a Wikiproject
Detecting articles needing images (eg. articles without images)
Detecting low resolution images to improve (eg. raster diagrams to be vectorized(

What do you think? Could it be a useful tool? MingoBerlingo (talk) 15:06, 26 July 2023 (UTC)[reply]

How can I resize SVG images (not objects)?

E.g. If I have a 100x100 px image, and want to reduce it to 20x20 px without any change in appearance. (Apart maybe from stroke width, which I can set manually in Inkscape.) It's helpful to have all images in a series set to the same size, line weight, etc., for display but especially when merging them into new images.

I understand 'scale' [under 'transform'], 'fit canvas to object size', etc. in Inkscape, but those will ruin the alignment of the object on the canvass.

If some program other than Inkscape could do this in bulk, that would be even better. I could then clean up the stroke width if I needed to in Inkscape.

BTW, I'm on Linux.

@Kwamikagami: Normally it would be best to ask these types of questions at Wikipedia:SVG help. However, if I understand your question correctly, you might use a text editor to try:

<g transform="translate(hhh,vvv) scale(0.2, 0.2)"> . . . </g>

or

<g transform="scale(0.2, 0.2) translate(hhh,vvv)"> . . . </g>

where hhh and vvv are horizontal and vertical adjustments, respectively.

Experiment with ordering of the translate and scale specifications, as this is a guess. I hope this helps. —RCraig09 (talk) 04:01, 10 April 2024 (UTC)[reply]

Thanks! I'll give it a shot. — kwami (talk) 04:04, 10 April 2024 (UTC)[reply]

Help with vectorizing a logo off Wikipedia

Hello,

I'm needing assistance with vectorizing a JPG logo outside of Wikipedia. I can't seem to get it to convert cleanly. Is someone able to assist me? Feel free to email me via wikipedia if you're able to help! Thanks in advance, Corky 18:47, 28 July 2024 (UTC)[reply]

Datasource issues

Can we please start requiring that vectorization requests cite a reliable source for the existence and usage of flags and other symbols, as opposed to WP:FOTW and other categorically unreliable vendors? There are enough fake and unverifiable flags that are tolerated on Commons for some reason, we really don't need to keep manufacturing more. Remsense ‥ 论 08:00, 24 September 2024 (UTC)[reply]

-== Images already in svg ==
+Hi there! I've been a wikigrpahist for some months now. I thought about a tool to find needed images in a Wikiproject and also to find low resolution images needing improvements.
-Wikipedia:Graphics Lab/Illustration workshop contain a section with a lot of images, raster and svg. The question of the user who opened the section, is for conversion request. A lot of those images are in svg and there is not conversion needed. I have attempted to remove images that do not need conversion but my edit is always reverted. Why? It is wrong? --[[Special:Contributions/151.71.42.64|151.71.42.64]] ([[User talk:151.71.42.64|talk]]) 18:54, 16 March 2022 (UTC)
+I called it [[User:MingoBerlingo/Visual content assessment tool|Visual Content Assessment Tool]], or simply VCAT.

-Hi,
+A working version of VCAT can be found at [https://aquets.github.io/VCAT-dashboard/#/dashboard VCAT-dashboard], you can try it using one of the samples of data I already extracted, or you can extract data for any Wikiproject using the [https://aquets.github.io/VCAT-dashboard/#/extraction extraction tool], a command line tool I created for this purpose.
-Wondering if there's anything wrong with [[:File:Kaktovik digit table.svg]], or if it's just me. (I've checked on two browsers.) The SVG has labels for all 20 digits, but the previews only show the labels for 0 to 9, with 10 to 19 being blank.
+Some of the actions you can do with this tool are:

-:{{done}} {{ping|Kwamikagami}} Seems to be an rsvg bug in which text with multiple x values are ignored. I've kept only the first value, and also moved the last line down for more whitespace.

-I was looking at [[:File:NPP flowchart.svg|NPP flowchart.svg]] and noticed that when I zoomed in it was pixelated like a raster image. Should I add the [[Template:Should be SVG]] template?
+I understand 'scale' [under 'transform'], 'fit canvas to object size', etc. in Inkscape, but those will ruin the alignment of the object on the canvass.
-I am interested in trying to convert it to a proper vector SVG but I might need some help. [[User:CoderThomasB|CoderThomasB]] ([[User talk:CoderThomasB|talk]]) 07:57, 24 October 2022 (UTC)
-:I have added the necessary maintenance template. Also this request should probably be put on the project page instead of the talk page.

-== Outline drawing wanted for article - how do I request it? ==
+BTW, I'm on Linux.
-I think the Wikipedia page on [[plastic bullets]] would be improved by a line illustration showing the shape and dimensions of plastic bullets used by Israeli riot control forces, illustrated in figure one of this academic paper and described on page 381 (The plastic bullet (Fig. 1) is a 5.62 mm missile, 1.5 cm long):
