PNGOUT

Why not optimize with PNGOUT? It usually gives better results (although it is a bit slower though). Perhaps you could give it a try. Cristan 01:24, 22 March 2007 (UTC)

I downloaded pngout, and did a few trial runs. Based on what I saw, optipng had better results. Thanks for poiting it out, though.Mikm 02:51, 22 March 2007 (UTC)

PNGOUT uses a superior compression method to OptiPNG, but in many cases, OptiPNG gives better results because it runs trials with different filter methods. With non-palette images, usually the best filter type varies between 0 and 5. PNGOUT will try 5 by default, but OptiPNG will try 0 and 5.

PNGOUT should be able to improve on OptiPNG if you try both filter methods (pngout /f0 and pngout /f5). Alternatively, you can run pngout /ks after running OptiPNG, which will read the PNG and detect and use the same filter settings OptiPNG used.

Another tool that's worth trying after OptiPNG is AdvDef, which again will keep the same filter.

Finally, whichever program(s) you use, you should be able to squeeze out a few more bytes by running DeflOpt afterwards. CountingPine 16:59, 27 September 2007 (UTC)

Advpng

Advpng usually gives better results, and is faster. However, it doesn't work on all PNG files. Why not use Optipng + Advpng? I often use Optipng + Advpng + Pngout to see what gives better results. Andrew pmk 02:54, 6 June 2007 (UTC)

Transparency

Hi. Is Pngbot able to change a background into transparency? E.g. in Image:Voriconazole.png, the background color is bright green, which does not look nice in articles (transparent or white would be fine). There are several more images of this kind. --Leyo 12:05, 20 July 2008 (UTC)

Method

Hello there,

Great to see someone's set up a PNG compression bot on Commons. I've been thinking about doing something similar on en.wikipedia; this must cover a lot of material, though.

I just have a suggestion about compression methods. I've been manually compressing high-visibility images on en.wikipedia for some time now, and made up a simple shell script to assist me. After some experimentation, I found that the best chain of programs for maximum compression is:

• PNGOUT (its zlib implementation and custom DEFLATE algorithm easily outperform Optipng, at the cost of some CPU and time on large images)
• advpng -z4 (maximum AdvanceCOMP restructuring)
• advdef -z4 (maximum AdvanceCOMP compression, using 7zip)
• optipng (sometimes catches a few extra bytes after the above)
• DeflOpt (fast, and almost always catches a handful of bytes on small images, sometimes kilobytes-worth on larger ones)

I'd imagine your output with that chain could easily be 25-30% smaller on average. PNGOUT in particular can take a good deal of time and proc, so you might want to only run it based on your rough compression estimate with Optipng (PNGOUT itself will not automate trials for you).

So, just some suggestions from a friendly neighborhood PNG compression fanatic.

Luinfana (talk) 19:01, 22 December 2008 (UTC)

• advpng doesn't seem to try different filters. I would suggest trying "optipng -f0-5 -force" to get optipng to choose a good filter (even if it may increase the size of the file as a consequence of its bad deflate) before handing over to advdef for a better deflate algorithm. Unfortunately that means you have to manually compare file sizes of the input and output... or just run the other tools later in the chain if you trust at least one of them to beat the input. --212.44.20.129 18:06, 26 January 2009 (UTC)

Tip: Categorizing images

---

Hello, Pngbot!

Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.

Here's how:

1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:

2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.

[[Category:Category name]]

For example, if you are uploading a diagram showing the orbits of comets, you add the following code:

[[Category:Astronomical diagrams]]

[[Category:Comets]]

This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".

When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations").

Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.

File source is not properly indicated: File:DRAfghanistanEarlyFlag.png

This media was probably deleted.

A file that you have uploaded to Wikimedia Commons, File:DRAfghanistanEarlyFlag.png, was missing information about where it comes from or who created it, which is needed to verify its copyright status. The file probably has been deleted. If you've got all required information, request undeletion providing this information and the link to the concerned file ([[:File:DRAfghanistanEarlyFlag.png]]). If you created the content yourself, enter {{Own}} as the source. If you did not add a licensing template, you must add one. You may use, for example, {{self|GFDL|cc-by-sa-all}} or {{Cc-zero}} to release certain rights to your work. If someone else created the content, or if it is based on someone else's work, the source should be the address to the web page where you found it, the name and ISBN of the book you scanned it from, or similar. You should also name the author, provide verifiable information to show that the content is in the public domain or has been published under a free license by its author, and add an appropriate template identifying the public domain or licensing status, if you have not already done so. Please add the required information for this and other files you have uploaded before adding more files. If you need assistance, please ask at the help desk. Thank you!

Please help replace this outdated license

Hello!

Thank you for donating images to the Wikimedia Commons. You have uploaded some images in the past with the license {{PD}}. While this was a license acceptable in the early days of Wikimedia, since January 2006, this license has been deprecated and since October 2008 no new uploads with this license was allowed.

The license on older images should be replaced with a better and more specific license/permissions and you can help by checking the images and adding {{PD-self}} if you are the author or one of the other templates that you can see in the template on the image page.

Thank you for your help. If you need help feel free to ask at Commons talk:Licensing or contact User:Zscout370.

The images we would like you to check are:

Copyright status: File:Crystal_Clear_action_forward.png

This media may be deleted.

Thanks for uploading File:Crystal_Clear_action_forward.png. I notice that the file page either doesn't contain enough information about the license or it contains contradictory information about the license, so the copyright status is unclear. If you created this file yourself, then you must provide a valid copyright tag. For example, you can tag it with {{self|GFDL|cc-by-sa-all}} to release it under the multi-license GFDL plus Creative Commons Attribution-ShareAlike All-version license or you can tag it with {{PD-self}} to release it into the public domain. (See Commons:Copyright tags for the full list of license tags that you can use.) If you did not create the file yourself or if it is a derivative of another work that is possibly subject to copyright protection, then you must specify where you found it (e.g. usually a link to the web page where you got it), you must provide proof that it has a license that is acceptable for Commons (e.g. usually a link to the terms of use for content from that page), and you must add an appropriate license tag. If you did not create the file yourself and the specific source and license information is not available on the web, you must obtain permission through the OTRS system and follow the procedure described there. Note that any unsourced or improperly licensed files will be deleted one week after they have been marked as lacking proper information, as described in criteria for deletion. If you have uploaded other files, please confirm that you have provided the proper information for those files, too. If you have any questions about licenses please ask at Commons:Village pump/Copyright or see our help pages. Thank you.
