Re: [Inkscape-user] qp conformal mapping
That's cool that you've already got something working!
I oversampled the original image, by reading the original image as if each pixel had another pixel (of exactly the same color) at the halfway point between the two integer pixel positions... sometimes you might have to oversample even more but you would just put more pixels of the same color in between...

*Libre Graphics Meeting 2016: Other Dimensions*
http://libregraphicsmeeting.org
The eleventh annual international Libre Graphics Meeting 2016 will take place Friday 15th until Monday 18th April 2016 in London, UK. This yearly event is an occasion for teams and individual contributors/artists involved in Libre Graphics to work together, to share experiences and to hear about new ideas. By Libre Graphics we mean Free, Libre and Open Source tools for design, illustration, photography, typography, art, graphics, page layout, publishing, 3D modelling, digital making and manufacture, cartography, animation, video, interactive media, generative graphics and visual live-coding. The Libre Graphics Meeting is not just about software, but extends to standards, file formats and actual use of these in creative work. LGM has become the place in which they can discuss their projects, coordinate their efforts and, crucially, to meet in person. Participants in the LGM include developers, designers, academics and activists from around the world, who are all passionate about Free/ L
ibre graphics software and technology.
*State of the Libre Graphics Union*
We begin each meeting with a joint session that brings together all things that have happened in our wide landscape over the last year. So, instead of slots in the schedule for general updates on each Libre Graphics software project, we invite every team present at LGM to submit two slides (maximum), with a short explanatory text that showcases the leaps forward that has been made over the past year. For first-time presenters and particular big or new topics/features in established projects, we encourage additional stand-alone submissions.
*Special focus: Other Dimensions*
In Toronto we celebrated the first decade of LGM, reflecting on the past and considering the future. For the 2016 edition of LGM we continue speculating and will expand Libre Graphics into Other Dimensions. We are looking for presentations and workshops that explore the dimensions of space and material: 3D modelling and animation, Libre architecture, Open Source product design and other fields of digital making and manufacture. We are also seeking contributions that offer reflections on the 'other dimensions' of open source communities and that engage with FLOSS tools in various contexts including but not limited to teaching, learning, practice and co-production. This represents a desire to address the future sustainability of the Libre Graphics movement, through a growth of the core projects and topics that will, we hope, allow us to welcome more and more FLOSS projects and participants to our community.
We are looking for:
- In-depth presentations of Libre Graphics code-contributions
- Showcases of excellent work made using Libre Graphics tools
- New and experimental projects in this area to meet the wider community,
including those in the field of 3D design and making
- Reflections on the activities of existing open source communities in
either the production of Free, Libre and Open Source tools or their use
Available formats (times include Q&A):
- Entry for State of the Libre Graphics Union (1-2 slides)
- Presentations (20 minutes)
- Workshops (1 or 2 hours)*
- Birds Of a Feather (BOF), discussion meetings or Hackathons (2 hrs or
more)
- Lightning talk (7 minutes, selected at the event unconference style)
*Practical Details*
Submission deadline: 10 January 2016, content selection notification by end of January 2016.

I am on Win7 and I got into troublex when I tried to remove the page group information from the pdf files. All the pdfs are empty now.
Now I would like to convert all the svgs in that directory to pdf and use the
gs -o image.pdf -sDEVICE=pdfwrite -dColorConversionStrategy=/CMYK -dProcessColorModel=/DeviceCMYK image.pdf as was proposed by this thread on Tex.stackexchange:
http://tex.stackexchange.com/questions/76273/multiple-pdfs-with-page-group-i...
I hope somebody can propose how to use which batch file in windows to perform this task. Sometimes ago I have done this on linux, but it was more than 15 years ago.
thanks for any help
Bernhard

No idea about batch files, but with Make, it is:
%.pdf: %.svg inkscape --without-gui --export-area-page --export-pdf=$@ $<

I developed this math and wrote a python program to do this sort of mapping, I thought maybe it would be interesting to have in inkscape:

Out of curiosity, I implemeted the python program as Inkscape extension to apply such a transformation to a linked or embedded bitmap image (using the path data of a helper path for the parameters of the transformation) [1].
Comparing the results (python 2.7.11, Pillow 3.0) with your example in the blog entry of the tranformed Mona Lisa image, I wonder how you filled missing pixels in the output image?

Hi Friends, I've been trying to use the Polor Coordinates tab of the Arrange dialog, to move some objects which are arranged in a circle, inward (or outward) without scaling them. Yes, I know it can be done with radially tiled clones, but I didn't want to do it that way this time. Attached is move-rad6.png, which is the "before", and I want to move those 6 objects toward the circle. No matter if I use the object's bounding box for the anchor point, or the rotational center, the result is the other attached image move-rad7.png. This is the same result, no matter if Rotate Objects is checked or not. This is on Windows 7, 64-bit with Inkscape 0.91, 32-bit, exe installer. I haven't tried in Inkscape 0.91, 64-bit, but I can if necessary. And these screenshots were made on layer 3, to avoid the transform attribute issues (which are mostly fixed, but not in 0.91). Another user on Windows 10 does not see this issue, but Idk which Inkscape version he uses. ( http://forum.inkscapecommunity.com/index.php?topic=307.0) I work with circles and objects arranged in a circle quite often, and have always wished for a way to move objects radially, in the same way that nodes can be moved radially by using the transform handles. Again, I know how to use tiled clones, but it seems like there should be an easier way to just move the objects on canvas by dragging them. I'm not technically aware enough to be able to suggest how it could be done. But I think would be a very useful feature....especially if it could work on ellipses as well. Meanwhile, I report this problem in case it might be a bug. Let me know if I can provide any additional info :-)
Thank you very much, brynn
