Inkscape | Extensions for Inkscape | 3D Printing library

Given the following rectangles in Inkscape .svg format, I want to find the absolute coordinates, of all four corners, of the second rectangle (in Python). Without writing my own matrix-transformations, or anything really complex.

You'd think there would be a library for this sort of thing. In fact, I found Python SVG Extensions - simpletransform.py, that sounds like it would to it. But it's in the deprecated folder of my installed Inkscape, with this notice:

This directory IS NOT a module path, to denote this we are using a dash in the name and there is no 'init.py'

And is not really importable, as-is. I might just try copy/pasting the code, but I don't have a warm-fuzzy that it will work at all.

And there seem to be a lot of questions/articles about "removing transforms", but they all seem to be related to "accidentally" added transforms.

Just to make things more complex - it looks like the x/y coordinates of the second rectangle - refer to the corner of the bounding-box, not the actual rectangle corner. I still don't really understand Inkscape's funky coordinate-system - it seems like the GUI is backwards from the actual objects. When I mouse-over the rectangle, its coordinates don't match what I expect to see.

Oh, and all units are set to pixels (I think).

I'm trying to print a raster visualisation. It renders fine in RStudio, but when I save it using the base svg device it comes out super blurry - as though each square of the raster is a massive pixel and they've been interpolated at some stage in the process.

Here's a reprex:

Is there a way to put text along a density line, or for that matter, any path, in ggplot2? By that, I mean either once as a label, in this style of xkcd: 1835, 1950 (middle panel), 1392, or 2234 (middle panel). Alternatively, is there a way to have the line be repeating text, such as this xkcd #930 ? My apologies for all the xkcd, I'm not sure what these styles are called, and it's the only place I can think of that I've seen this before to differentiate areas in this way.

Note: I'm not talking about the hand-drawn xkcd style, nor putting flat labels at the top

I know I can place a straight/flat piece of text, such as via annotate or geom_text, but I'm curious about bending such text so it appears to be along the curve of the data.

I'm also curious if there is a name for this style of text-along-line?

Example ggplot2 graph using annotate(...):

Edit: Here's the data for the first two trial runs in March and April, as requested:

How do I convert a svg image to png, save it to a file, and collect basic information about it?

GCode is language used to tell multi-axis (CNC) robots how to move. It looks like this :

After some initial problems I was finally able to set up a self-hosted GitLab Runner on my personal laptop.

I'm now looking into how this runner works and how I can tweak it's environment to my needs. I modified the YML file to run a simple command echoing the PATH environment variable:

I want to automate "raster to vector" conversions. PNG to SVG. (most Qs here on SO are the other way around)

I have tried the old command line tool autotrace on Linux, but I could not get it to run. I've tried to install a package, and to compile it from the source. Nope.

Then I've realised that Inkscape has "autotrace" now integrated in its codebase. I'd like to convert simple sketches from PNG to SVG.

And I want to do this in a Bash for-loop , with different autotrace settings (number of passes; ignore Speckles with max X pixels width) etc.

I've tried the "action" command-line option

I have a PDF document (that is my schoolbook) and the problem is that although the text is printed normally, it is copied in the form of some random glyphs. I found, that it is because of text being encoded on cp1251 but trying to be decoded as cp1252 (or viceversa idk but copied glyphs belong to 1252). Pasting text to decoder from 1252 to 1251 I can get the original text (pic related)

To solve my problem of text searching and copying I just used OCR, but maybe there is a way to change it's encoding in some pdf headers? Also I do need to copy some of the illustrations for school seminars, but Inkscape and AI still output theese glyphs in 1252.

Opening the text in Adobe Acrobat DC, I saw that he was complaining about the font 1251 Times. In Npp i found such ones

I am trying to achieve the following using a python script:

1. Read in an SVG design file (with images)
2. Manipulate the SVG file
3. Convert this to a web-ready PDF and a print-ready PDF

My problem is with the conversion of the RGB PDF to the CMYK PDF. An SVG with a 15MB photo in it will export as a 15MB RGB PDF, but then convert (using GhostScript) to a 3MB CMYK PDF. When trying ImageMagic, the resolution of the output PDF is determined by the density and I can't find how to keep the PDF's canvas size while setting the density.

So far, I have a script which reads in the SVG files and does some manipulation (add a logo using svgutils, change some text by scanning through the SVG text file). It then uses Inkscape to export the web-ready PDF (using "--export-area-page" and converting the text to paths) and a temporary PDF (using "--export-margin=X" where X is the bleed size, also converting text to paths). The temporary PDF is what I need, except it is RGB rather than CMYK. So, I then want to convert this file (Inkscape does not work with CMYK).

This is the function I am using to convert the file (it is setup with GhostScript and also I was trialling ImageMagick):
