In the 2016 Hyndburn Borough Council election, ONLY two ward-seats were won by Conservatives / the two neighbouring Barnfield & Baxenden wards (bottom-RIGHT corner of map) , the erroneous [St Oswalds ward, bottom LEFT corner - looks like "Florida"] was won by Labour and should be paint-filled in as RED, not as BLUE.
I am currently working on a draft-copy of the next 2020-Hyndburn Borough Council-elections results page, which references the previous 4yr old results. Over the past decade, I've relied upon other 3rd-party contributors to "edit/tweak" the results-maps, as I myself an NOT any kind of a "paintshop-expert".
. EG, in 2014 "they" picked a much darked BLUE than previously/subsequently used ... and 'again' in 2018, another 'darker blue' was used ...
@TextClick: I can do these guys, but I notice that in all the online versions of the OCX, the horizontal slashes are present only across the "O" and the "C" and not across the "X". Should I omit the slashes in across your PNGs' "O"? —RCraig09 (talk) 19:38, 23 April 2020 (UTC)[reply]
@RCraig09: I'm assuming you meant omit the slashes from the "X", so yes, please do. However, if you meant the "O", both the "O" and the "C" have horizontal slashes across them, so no. TextClick (talk) 01:57, 24 April 2020 (UTC)[reply]

Please help with Unsafe CSS removal
Hi ,
As EugeneZelenko was suggesting I created a logo on SVG but when I try to upload it on commons it says that there are unsafe CSS in the style element of uploaded SVG file. Is there anyone who can please help me to fix this issue ? Many thanks--Neverstopthat (talk) 15:38, 15 March 2020 (UTC)[reply]
Neverstopthat I don't know which issues it complains about but at this link you can test a svg file before uploading. For your file it complains about "Font type Open Sans Condensed is not available in Wikimedia software.". Not all fonts work here and there is a link for you to check which fonts that work. At this place you can also check your file. Very often it's very good to save it as "optimized svg", then check it at those places and see what is wrong, if any. If it passes this last check place you can also put out "Valid W3C code" on the file, it's good to do so. --Goran tek-en (talk) 16:42, 9 April 2020 (UTC)[reply]
@Neverstopthat: The current file has CSS with a @font-face rule that loads a font from a url(data:...). Such a URL is probably unsafe because fonts are programs. The URL could also be unsafe because an arbitrary font may not have a free license. The SVG file should not define a font; it should just use available/generic fonts.

The indicated original source for those graphs is doi:10.1001/jama.298.6.644, which contains a few graphs and a table with limited data. I was unable to find the source data at the resolution used to make those graphs. I was able to find graphs in the supplement.

Can someone upload a new version of this file with the x & y axes correctly labelled i.e. x is the horizontal axis and y is the vertical axis Nthep (talk) 18:06, 2 April 2020 (UTC)[reply]
I've been making several illustrations and uploading them to Wikimedia Commons, and to preserve resolution, I want to upload them as vector images. I had originally been using the PDF format, but I see that these images are downsampled for display on pages. I then tried using SVG, but when the images get rendered by Wikimedia Commons into PNGs for display, I've often found that text isn't rendered properly. I'm attaching one image as an example, but this has happened with many images. You'll see that the text is fine in the original SVG, but not in the rendered PNG. I intentionally switched to Wikipedia-compatible fonts (liberation, deja vu), but this did not solve the issue. Do you have any suggestions for how to fix this going forward?
Rob Hurt (talk) 18:15, 9 April 2020 (UTC)[reply]
Graphist opinion(s)
Hi, Rob. As an SVG newbie I discovered the same problem. The problem is the way Wikipedia renders fonts, and as far as I can tell there is no easy "solution" in the true sense of the word. A request to solve the problem technically has been submitted, but it's an old problem so salvation is not at hand. You can "work around" the problem, however: see the purple section of this link “”[2]. Good luck to you, sir! —RCraig09 (talk) 23:50, 9 April 2020 (UTC)[reply]
The fonts in the image are too small. Although MediaWiki does have problems rendering small fonts, that does not seem to be the problem. When MW renders fonts below about 15px, the letter spacing becomes erratic. That's not the problem for the given file. The fonts are just too small for the height of the image.
The image is 3000px high, but the fonts are (on quick inspection) in the range of 28 to 56px; that is 0.9% to 1.9%. Although those fonts are readable when printed out on a letter-size page, the images on WP are usually displayed much smaller. If the displayed image height is a 2 inches (51 mm), then the 56px font will be 0.037333333333333 inches (0.95 mm) tall. One would not expect such a font to be easily readable.
Thank you for the suggestion. Interestingly, it's actually the larger fonts in the image that I'm having problems with--the smaller ones are fine. I converted the fonts to curves, which worked in this case. Rob Hurt (talk) 22:57, 10 April 2020 (UTC)[reply]
Rob Hurt I just want to give you some reflections regarding size. I downloaded your file but when I opened it in Inkscape and looked at the page size the unit (px, mm, ...) is not set correctly. When I draw a box to check the size it's about 8000 px (pixels) high. That is not good (to my understanding) to draw something that big if it's intended to be used as an illustration within wikimedia. "Most" screen resolutions are about 1080 px high or slightly more. This is what I assume that the viewer of my graphic work probably will have. Then there is always frames and stuff both at top and bottom so the actually view area is even less. So in my graphic work I try to use that height and then I think about the size of text. I will never know at which size an illustration/map will be viewed at. So if I can't get a specific size from the requester I try to stick to max 1000 px in height and then I make it work in 100%. Then I can view in Inkscape or whatever program one uses that the illustration/map is legible at 100% regarding text, illustrations, lines etc. So for the illustration you link to it's very hard to know how it will be viewed when the page size is not set correctly. I write all of this just as my experience and I mean all well with it. --Goran tek-en (talk) 18:06, 17 April 2020 (UTC)[reply]
The quality, size and resolution of the PNG image is sufficient for any use imaginable here. Therefore it would be a waste of time to vectorize it beside the fact that the complexity of the many dents and holes makes the task extremely time consuming. Stay with the PNG whose quality is far beyond of thousands of traced and vectorized files here. - MaxxL - talk16:49, 15 April 2020 (UTC)[reply]

Image corruption detected in File:... created by JPEGcrop application
[[File:Han-talers.jpg]]: Drawings of two coins
Article(s): [[]]
Request
To enable categorizing and using these two coin drawings independently, I wanted to split the original image and drop the embedded captions, but recalled I could not use Commons:CropTool as this would replace the original image by the (one and only one) cropped version.
However, both attempts were flagged with error messages e.g.: "Image corruption detected in File:2-3 Thaler 1721... Hello HReuter, it appears that the version of File:2-3 Thaler 1721 Georg Ludwig.jpg which you uploaded 2020-04-10T12:25:38Z is broken... " and the uploads could not be viewed -- no idea why.
As a workaround, I did similar crops using an old version of Photoshop I had and could now upload the resulting single images without any problem, but lossy (at least in principle) and with larger filesizes.
While I could leave it this way, I am still interested to learn what went wrong, or how to do better, even more so since a similar situation may arise anytime.
@HReuter: You can upload to a new file using toolforge:croptool, it's an option that appears after previewing the crop. In many cases, it will in fact be the default option. I can confirm that firefox refuses to open the image, but ImageMagick (the software that Wikimedia uses to make thumbnails) and jpegtran (the software that CropTool and Jpegcrop use) are entirely fine with it. There are three typical types of corruption that I see: Missing end marker (some of the image data got left behind), two images in one file, and improper encoding. This file appears to have all the data, doesn't have anything tacked on to the end as far as I can see, and has the correct w:JFIF encoding. @TheSandDoctor: do you have any ideas? --AntiCompositeNumber (talk) 17:33, 15 April 2020 (UTC)[reply]

The resolution of this PNG image is excellent. I do not see any application here that requires a higher resolution. To vectorize this COA would end up in a loss of detail quality and authenticity. Enjoy the quality of this image which is far better than the majority of COA files available here. - MaxxL - talk16:56, 15 April 2020 (UTC)[reply]
Hi, Jan. Since the image has only 436 × 500 pixels, I'd like to try to improve it using Inkscape (new hobby!). MaxxL is correct that there would be a loss of "authenticity" but I know I can make the details clearer. User:Janbery: please tell me if you want me to proceed, because it will take a serious amount of time. —RCraig09 (talk) 06:04, 17 April 2020 (UTC)[reply]
@RCraig09: Hello, thanks a lot for help. I can do basic things in Inkscape, but this is way harder. If you have time, I will be very pleased. Take your time, it's not urgent. I don't know, if I can do anything for you, but if you have any idea, I will be happy to help. One more time, thank you. Best regards, --janbery (talk) 08:50, 17 April 2020 (UTC)[reply]
I am sorry, but I have to intervene. Citing Voltaire, "The Better is the enemy of the Good"
@RCraig09: - Good job. But as you have experienced it now how difficult and time-consuming the task is. As so many details are insufficient (e.g. Bohemian lion has no yellow claws, lines and borders are mixed and its thickness in wrong order, etc) this is not an acceptable and suitable vectorisation. - MaxxL - talk07:13, 21 April 2020 (UTC)[reply]
Small coat of arms of the Czech Republic.svg
— User:Janbery: @MaxxL: Definitely, the lion was the most difficult and time-consuming portion! Earlier, I could not find a clear image of the Kadaň lion. However, now, you mention the "Bohemian lion" and today I found the image at right (for the entire Czech Republic). The Czech Republic lion is much clearer. Can the Czech Republic lion be substituted into the Kadaň coat of arms? (I apologize for not understanding these things.) —RCraig09 (talk) 16:41, 21 April 2020 (UTC)[reply]
@Janbery: - The rule is stated in the VVA template flag: "This is a vector version of this file. It should be used in place of this raster image when not inferior.". It is obvious that the JPG version is superior in detail and authenticity. Having explained the shortcoming of this SVG the replacements have to be reverted. - MaxxL - talk07:13, 21 April 2020 (UTC)[reply]
@MaxxL: @Janbery: Can you tell me if the updated version, using the improved lion, is acceptable? Is there something more that I can do? If needed, I would rather do a little bit more work and have it be acceptable. —RCraig09 (talk) 18:12, 25 April 2020 (UTC)[reply]
Dear @RCraig09: - I personally appriciate your contribution of this CoA. But judging it as a true vector version it fails. It takes more. Just loading both images in inkscape in two levels shows the short commings. It takes more than graphic skills and inkscape experience to deliver a sufficent result. i am glad you took on the challenge buit the original is still "better" than your faksimile. Pls don't be discouraged to take other graphic vector improvments. - MaxxL - talk16:42, 26 April 2020 (UTC) (handeicaped and using speechrecognition in place)[reply]
I was hoping you MaxxL could be more specific as to why my new graphic fails. Is it the visual appearance (authenticity)? Or is it a problem internal to my SVG construction? (I don't understand why "two levels", or what the "shortcomings" are.) —RCraig09 (talk) 16:56, 26 April 2020 (UTC)[reply]
I can put in a lookalike lion on this arms from the original picture. If its OK by RCraig09 I'll put it in. Regards, --D'Arch (talk) 17:40, 26 April 2020 (UTC)[reply]
First, there are several versions online. This seems to be the original drawing. See the differences in the lion. However, the request is for the edited JPG version. There's no lion with golden tongue or crown. The PNG. drawing is in high resolution, it should not be a problem to make a vector of this with an authentic look. That is, definitely use the original lion, not stick something on it that has a different style.
See my version, which will be 90% equal to the original. If I wish this to 100%, skewed or uneven lines from the original would have to be copied exactly. Your version will be 60% because you have used a lion in a different style and appearance. --D'Arch (talk) 05:20, 27 April 2020 (UTC)[reply]
You User talk:D'Arch have certainly done an amazing job. I wish I had a better 'original' to work from. My Google searches only turned up pixellated images. I'm still unsure what the authoritative "right" CoA is. But you have certainly made a high-quality image that mostly closely matches Janberry's original version File:Coat of arms of Kadaň.png. —RCraig09 (talk) 16:52, 27 April 2020 (UTC)[reply]
@RCraig09: - I just have to disclose a little secret: Arch has a more than 15 years experience in artistic heraldry. Only three more "masters" of his skill are still busy here and you have to be patient as their appearance is rare and suddenly. ;-) - MaxxL - talk17:08, 27 April 2020 (UTC)[reply]
@ RCraig09, keep on drawing, you are doing an excellent job. Your first version is always better than version two, because it is authentic. Authenticity is more important than its beauty or details. Although it is less clear, the lion just belongs to that drawing. @ MaxxL thanks for the kind words, it is nice to see that you are still here. Kind regards to all and have a nice day.

RCraig09 You created and uploaded this file as a svg file and as it contains raster graphics it is not a true svg file. To show this it's very good to add some of the templates showing this;
This image is not a real SVG file and is just a wrapper containing one or more raster graphics without vector coding. Using SVG as just a wrapper is undesirable. Note: This template should be used if the SVG file contains only raster graphics. If the SVG file contains both vector and raster graphics, then use {{BadSVG}}.
or
All the SVG images in this gallery contain embedded raster graphics.[3] Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics. Note: This template is only supposed to be used if the SVG file mixes vector and raster graphics. If the SVG file only contains raster graphics {{FakeSVG}} is supposed to be used. See also {{TopoSVG}}.
and there are several others. I do understand your point on easier translation but a lot of people do not know how to check if a svg contains raster graphics and there fore it can not be used as a true svg. One could upload a xcf (Gimp) or Photoshops own file format so that text layers is saved and then it's as easy to translate. --Goran tek-en (talk) 18:12, 29 April 2020 (UTC)[reply]
Thank you, User:Goran tek-en. I only learned Inkscape in February, so I am a newbie!

RCraig09 That is great. I don't know how much you know about different file formats and the differences between vector (svg) and bitmap (png, jpg...) but if you don't it would be useful for you to search for "difference svg bitmap" on internet and study that. Also we have a lot of info here att commons also; svg info, creating templates Inkscape, templates svg and much more. It's also very good to work towards creating Valid svg code in the files. As I said I don't know how much you know so please see all of this just as suggestions if you didn't know. If you already know I'm sorry to bring it up.

Better illustration for synthetic aperture radar
Synthetic Aperture Radar (2016)
Synthetic Aperture Radar.svg (uploaded 27 April 2020)
I will start this project and get back to you within a day or two.... Question: Should that ellipse appear to be lying flat on the ground, or in a plane including the beam and emitter? Request taken by RCraig09 (talk) 03:19, 27 April 2020 (UTC)[reply]
Beautiful, thank you! Yes, there are some things I should have clarified. First, the length of the synthetic aperture is the total travel distance of the aperture (the place where the red lines exit the box) along the azimuth. Is there a way we can illustrate that more clearly? That's probably the single most important point of the figure, and I know the original file I submitted didn't depict it well. Second, the swath width should be elongated along y so it covers the fill width of the red circle. Finally, it might make things simpler if we made the y axis pass through the red dot on the left, and then instead of the black dashed line, we had theta_a going from the left red dashed line to the y axis. Thanks again, and please let me know if you have other questions! Rob Hurt (talk) 19:43, 29 April 2020 (UTC)[reply]
I'm not sure what you mean by "where the red lines exit the box" since the red lines exit the box at is, literally, a point, not a distance. Which two points in the diagram, exactly, determine the SA's length? And which two points, exactly, should those two points be aligned with?
No problemo re width of swath. That change actually simplifies things!
Sure, sorry about that. The box itself is actually moving along the azimuth, sending out and collecting pulses of light as it goes. So the synthetic aperture is the distance from the point where the red lines exit during the first pulse, to that point when the box has moved all the way down the azimuth. Maybe this picture (https://www.dlr.de/content/en/articles/missions-projects/terrasar-x/synthetic-aperture-radar.html) makes the scanning nature more clear. Does that help some? Maybe we could duplicate the box and the lines coming out of it and paste a more transparent version of it further down the azimuth to show the motion. Or would that make the image to cluttered?

I had always wondered why the 2016 diagram was so different from most other SAR diagrams, in not really showing motion! It makes sense to introduce a second transceivers/ellipse set. I should complete that (non-trivial) change within a day. —RCraig09 (talk) 21:52, 29 April 2020 (UTC)[reply]
I just couldn't wait. Version 4 is done! The details of the angular representations were tricky, but I think everything's proper now. —RCraig09 (talk) 04:26, 30 April 2020 (UTC)[reply]
Could someone make a nice image showing the concept of time-of-flight? Here are some images for inspiration: ([4]), ([5]), ([6])
The concept it needs to depict is that a laser sends a pulse of light at the target, the pulse bounces off and gets detected by the camera, and the time that this process takes is measured. Then the distance can be calculated as: distance = (speed of light) / (time of flight). Please let me know if there are any questions! --Rob Hurt (talk) 21:13, 29 April 2020 (UTC)[reply]

Graphist opinion(s)
Is a simplified version of the timing diagram in Fig. 9 of this patent be OK? The patent shows multiple echoes; we would be concerned with only one echo. A time-domain diagram really shows the D=V/TD=VT relationship. I'd rather make the time axis vertical and the distance traversed horizontal. —RCraig09 (talk) 22:06, 29 April 2020 (UTC) Formula corrected RCraig09 (talk) 04:30, 1 May 2020 (UTC)[reply]
Sure, I think that's a great idea! It certainly seems like you understand the concept, so I think your interpretation of how to illustrate it is as good or better than mine :) Rob Hurt (talk) 01:01, 30 April 2020 (UTC)[reply]
