How do I convert a PNG to PDF with only the default packages on 11.10?

Question

Openning a png file in ubuntu, I can see the menu item for 'print to file'. How can I do the same on shell? PS: I prefer installing no extra package, due to lack of root access.

EDIT: the operating system is ubuntu 11.10

Solution 1

convert xyz.png xyz.pdf should do the trick.

See man convert for more options.

Solution 2

If you want to convert multiple images, e.g. png files, into one single pdf use convert with the specified pdf filename at the end

convert *.png mydoc.pdf

It will merge all png files into a sinlge mydoc.pdf file in a descendant order.

Solution 3

In 18.04 LTS, open image using ImageViewer; then print to file as a PDF.

+1 - additionally you can use wildcards: convert *.png file.pdf

does this require extra packages?

Also there by default on lubuntu 12.10.

Be careful if you use wildcards, files might not appear in the desired order, especially if filenames contain numbers (for example, a file named 17.png will precede a file named 2.png). To preview the order in which they will be merged into the pdf file, you can use the command echo *.png.

If you're using more recent versions of Ubuntu, you probably need to make this security exception: askubuntu.com/questions/1081895/… PDF looks beautiful, original images are unharmed.

It seems more like a problem of a security policy of the environment you are working on. Sorry, I cannot say too much about that error.

Batch conversion of png to pdf has details on the 'convert-im6.q16' issue.
