@Skillmon Yes, I‘ll do that. I was struggling a bit with changing the font size or adding \sloppyinside these example environments. Will look into this again.
sob can someone tell me how to simplify \_user_do_obeylines: in my answer at tex.stackexchange.com/a/666512/87678? I really do not understand just about every aspect of the peek macros…
Assume a XeTeX-engine is in use for creating a document where some images are included via \includegraphics. How can you specify the resolution at which the image shall be included into the pdf-file created by xdvipdfmx? With pdftex-engine I would use \pdfimageresolution=.... With luatex-engine I would use \pdfvariable imageresolution .... Is it possible to have the XeTeX-engine-created .xdv-file "communicate" a desired image-resolution to xdvipdfmx?
Or do I need to provide the image-file in the desired resolution?
Assume I have an image "test.jpg" at 150 dpi, height 2in, width 4in, and I wish it included scaled to height 1in, width 2in, using a pdftex-engine. Will \pdfimageresolution=300 \includegraphics[scale=.5]{test.jpg} do the trick so that the pixel-data/the amount of pixels in the image in the pdf is the same as in test.jpg except that a pixel in the pdf is considered as half as wide and high as a pixel in the .jpg-file?
What would happen with \pdfimageresolution=150? Would the amount of pixels in the pdf-file's image be a quarter of the amount of pixels in the jpg-file?
@Skillmon Non-Chinese examples added (not English, but it chose text snippets that show the text flow). It took me a while to get something that fit the tight column spacing …
One can use \includegraphics[page=5]{foobar.pdf} for including the 5th page of foobar.pdf in one's document. (I think internally it is about the page whose pdf-page-index equals the value of the page key minus 1.) Where can i find information on how to implement a similar mechanism for denoting the page to include by specifying its pdf-page-label instead of its pdf-page-index? (In case pdf-page-labels are not unique include the first page with the page-label in question.)
@DavidCarlisle What a pity ;-) Thank you. (For a document that has many png files that take a long time to include, I came up with the idea of using \includegraphics to put all the png files in order into an auxiliary pdf file, and in the actual document use the corresponding page of the auxiliary pdf file rather than the png file. At the moment you need to know the page-index belonging to an image in the auxiliary pdf-file.
With hyperref you can easily give each page of the auxiliary pdf file a pdf-page-label corresponding to the name of the png file. Then in the actual document, in the \includegraphics command, specify the page not by the page-index but by the page-label...).
@DavidCarlisle Yes, I know. But in this case a separate single pdf containing all images is required anyway. So the idea was that I could probably use that instead of creating another set of pdf-files. ... But it's probably not really worth delving into that idea. ;-)
@DavidCarlisle ... it would probably be a nice exercise for me to learn more about LuaTeX. ;-) But I won't do it. When starting struggling I might come up at TeX LaTeX Stack Exchange with too many weird questions...
@DavidCarlisle Using pdflatex/graphicx-package for shipping out a box containing the image as the only page of the document is easy. (Just need to set \pdfpagewidth/\pdfpageheight and then do s.th. like \shipout\vbox{\kern-1truein\hbox{\kern-1truein\box\BoxWithImage}}.)
Apart from the fact that calling a batch converter is easier, I wonder whether the pdf files produced the pdflatex-way would serve the purpose well or whether the results you get with netpbm/ImageMagick/convert would serve the purpose better.
