How to log scaling applied by includegraphics?












2















I'm currently working on a large-ish document that contains a lot of screenshots. These range from relatively small dialog boxes or details of the screen to some very large overview pictures. I currently use the option width=textwidth for the larger screenshots to scale them down to fit the page (somewhat). I also need to apply some scaling to the other screenshots - some larger images need to be scaled down, some details need to be scaled up.



Now I would like to use a small set of scaling factors throughout the document. The screenshots are all taken from a single application, and I'd rather not have the font size and UI details change size from image to image. To achieve that, my current plan is to use only two or three fixed scaling factors throughout the document. I can apply these manually in the source code, but I need to determine the actual values first. For that, I was thinking about setting every image to width=textwidth, recording the actual scaling applied and then classifying and adjusting the scaling factors.



As far as I can see, the original size and the requested size of each image file is contained in the log file, but on separate lines and in a syntax that is not very parser-friendly. Is there a better way to log the actual scaling factor that is applied to the image?

  • to logarithmic is of course no verb (as long as I am not errant), but given some usual laziness with titles here, the title can be misunderstood at first

  • If you use adjustimage from the adjustbox package the previous width of the image is provided as width dimension register which can be used with ifdimwidth>somevalue etc. You could also just store the image in a box and take the box size as indicator (which is what adjustbox acutally does).

  • and then there are the min width and max width keys provided by adjustbox which only scale if needed. Something like adjustimage{min width=0.5textwidth, max width=textwidth}{image file name} will work to ensure that images are neither to small or to large.

You could try this:



documentclass{article}

usepackage{graphicx}

usepackage{etoolbox}

makeatletter

apptoGPT@setup@scale{wlog{x-scale: Gin@scalex, y-scale: Gin@scaley}}

begin{document}

includegraphics[width=textwidth]{example-image-duck}



includegraphics[width=textwidth]{example-image-a}



end{document}


It will log



File: example-image-duck.pdf Graphic file (type pdf)

x-scale: 1.8696, y-scale: 1.8696


and 



File: example-image-a.pdf Graphic file (type pdf)

Probability when a professor distributes a quiz and homework assignment to a class of n students.

Image
0 0 $begingroup$ Need help with this problem. Suppose our lazy professor collects a quiz and a homework assignment from a class of n students one day, then distributes both the quizzes and the homework assignments back to the class in a random fashion for grading. Each student receives one quiz and one homework assignment to grade. (a) What is the probability that every student receives someone else's quiz to grade, and someone else's homework to grade? (b) What is the probability that no student receives both their own quiz and their own homework assignment to grade? In this case, some students may receive their own quiz, and others may receive their own homework assignment. (c) Compute the limiting probability as n approaches infinity in each case. ...
