This looks like a fun toy https://www.youtube.com/watch?v=ccpsyRipHlk

samcarter replying to L.J.R.

I've recently read about it on Mastodon. Looks indeed very interesting.

[typst](https://github.com/typst/typst) looks very promising. Hope it will replace TeX in the future.

Great suggestion, thanks a lot! At first, this tool refused to work saying  
```  
Image with transparency and a bit depth of 16.
This is unsupported due to PIL limitations.
error: Refusing to work with multiple >8bit channels.  
```  
however I didn't need any transparency here, so I:  
- opened the original PNG image in Gimp;  
- picked a suitable background color;  
- added a new layer filled with this color;  
- merged the original layer into the new background layer;  
- removed the alpha channel from the resulting layer (right-click on the layer → Remove Alpha Channel);  
- used File → Export As... to write a new PNG file without the alpha channel.  
After this, `img2pdf` worked quite fine on the new file. The sizes of the original PNG and the resulting PDF file are very close (the PDF file being slightly smaller: 17,023,902 vs. 17,050,961 bytes).  
  
Besides, your link taught me the existence of the `pdfimages` tool which is fantastic to:  
- list all images embedded in a PDF file (`pdfimages -list foo.pdf`);  
- extract them, e.g. with `pdfimages -all foo.pdf someprefix` (there are options to choose output formats, `-all` being equivalent to `-png -tiff -j -jp2 -jbig2 -ccitt` according to the `--help` output).  
  
:-)

Use `img2pdf` instead. It's a command line tool that is really well behaved. See its [README that contains comparisons to other tools](https://github.com/josch/img2pdf#comparison-to-imagemagick)

Hi all!  
  
In order to convert from PNG or JPEG to PDF (a photo to be printed at a shop to put in some enclosing on a grave), my naive way is:  
```  
\documentclass[border=0mm]{standalone}
\usepackage{graphicx}
\begin{document}
\includegraphics{image}
\end{document}
```  
Before doing so, I've tried ImageMagick's convert but the resulting PDF size was much smaller than the original PNG, so I guess ImageMagick degraded the image by using some default resolution. Apart from looking up the PNG resolution and somehow feeding it to ImageMagick, which is too cumbersome to my taste, is there an obvious way I have missed (on Linux)? Thanks!

No problem, just keep us posted. :)

AnonymousRabbit replying to निरंजन

Not my decision to make (sorry).

or even https://www.shortlist.com/media/images/2019/05/50-best-hollywood-beards-4-1556697841-CDRC-column-width-inline.jpg

something like https://images.halloweencostumes.co.uk/products/52613/1-2/biblical-moses-wig-and-beard.jpg ?

topnush

she needs a beard! Just somehow a slightly different looking one

samcarter replying to topnush

You are welcome to take the duck to a barber

topnush replying to samcarter

I love the idea! The beard looks a bit too much shaving cream or icing right now

samcarter replying to topnush

```  
\documentclass{standalone}
\usepackage{tikzducks}

\begin{document}
	
\begin{tikzpicture}[scale=2]
	\duck[recedinghair=lightgray!70,beard,book={\parbox{1cm}{\centering\tiny 10 Quacks}},bookcolour=gray]
\end{tikzpicture}	
	
\end{document}  
```

topnush

what about Moses duck?

निरंजन replying to AnonymousRabbit

I would love to be a part of it! :)

Thx!

Skillmon replying to AlbertNashr

It's easier for the others if you use a single account (and in the long run for yourself... we rabbits know)

Skillmon replying to AlbertNashr

it is possible, there are two different methods to "log in", on your profile page there is the section "link another device to this account", that one will be invalid after 1 minute, but the key created in the next section "account recovery" can be used indefinitely.

Concerning using the same topanswers.xyz/tex account on two machines: Is it possible to do this if I can access the two machines, say, only with an interval of ≥1.5 h in between (because they are simply far apart and off unless someone actively uses them)? Should I bother at all having one and the same account?

samcarter replying to AnonymousRabbit

... maybe it ate pineapple pizza :P

topnush

my mistake

topnush

oh it is a wolf after all

topnush replying to AnonymousRabbit

:)

AnonymousRabbit replying to topnush

not sure what it is, but it looks green.

topnush replying to samcarter

interesting new interpretation. A wolf is a good choice here in fact

samcarter replying to topnush

To me it looks like a *wolf*  is wearing a hat :)

topnush

question for the experts. Does it look like the fox is wearing its hat ? https://topanswers.xyz/image?hash=f0b63582053faaa9bff6057b5fe75a206a7e765ebeb6e0cce78c65abb243f6be

AnonymousRabbit replying to Dr. Manuel Kuehner

a few people play with the idea to start from scratch, but at this point it's merely a thought experiment. So yes, consider this a joke :)

Dr. Manuel Kuehner replying to Skillmon

Is `xbeamer ` a new version of beamer (as a joke)?

Skillmon

You close your eyes for a few hours and the site is flooded with `beamer`... Time for `xbeamer` to put an end to this :P

samcarter replying to Dr. Manuel Kuehner

thx! I will write something up tonight :P
