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)

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)

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

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)

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)
