Hello, 3 months ago I saved a notebook which was fine - but I am not sure which version was available at this point. However, actually I am using 11.2.0.0. The code is ``` WrapText[str_, transformation_] := Rasterize[ Module[{text}, text = Style[str, Bold, FontFamily -> "Helvetica", FontSize -> 12, LineBreakWithin -> False]; Graphics@ Cases[ImportString[ExportString[text, "PDF"], "TextMode" -> "Outlines"][[1, 1]], FilledCurve[a__] :> FilledCurve[a], Infinity] /. transformation], ImageSize -> {300, 300}] Export[NotebookDirectory[] <> "Test.jpg", transformationSpiral = {x_Real, y_Real} :> {Cos[-x/(12 Pi)]*(y + 4 + x/18), Sin[-x/(12 Pi)]*(y + 4 + x/18)}; WrapText[ "All human beings are born free and equal in dignity and rights. \ They are endowed with reason and conscience and should act towards \ one another in a spirit of brotherhood.", transformationSpiral]] ``` with following result: ![6699Test.jpg](https://global.discourse-cdn.com/wolfram/original/3X/4/9/4984bb5e6580925fb4f395da39a7a99db82cb6db.jpeg) The code is from [here](https://mathematica.stackexchange.com/questions/5719/how-can-i-wrap-text-around-a-circle) and should look like this (and definately did it 3 months ago…): ![yoOrK.png](https://global.discourse-cdn.com/wolfram/original/3X/5/3/5301630477b16d4ff137ee0465a9158a3f4c8629.png) . On an old os-backup with MMA 11.0.1 it works fine - except that it looks a bit different and the message “file was created with a newer version”…any ideas whats going on here? Was there any version between 11.0.1 and 11.2 on the Raspberry? I am almost sure I saved it with actual 11.2 - but why does the output look so ‘corrupted’ now? And how could I fix it? Many thanks for your help and ideas, ---

Hello Michael, I don’t have this problem with version 11.3 on Windoiws 7 x64. I recommend contacting the tech support. ---

Hi, I cannot reproduce this issue on MMA11.2 or 11.3 on OSX either. Cheers, Marco ---

Hi Michael, no problem on `11.3.0 for Linux x86 (64-bit) (March 7, 2018)`. Nice code, thanks for sharing! How on earth you could come up with ``` ImportString[< data.pdf >, "TextMode" -> "Outlines"] ``` I cannot find this anywhere in the documentation. Regards – Henrik ---

Interesting code. Why do you write the replacement rule ``` FilledCurve[a__] :> FilledCurve[a] ``` in Cases? Wouldn’t the simple pattern `FilledCurve[a__]` have the same effect? ---

The problem seems to be somewhere in my OS I think (but where/why?). I did an apt-get update+upgrade on my os-backup - and this sd-card with MMA 11.2 now renders it as it should. Strange…but, however, it works fine now…as I saved it. > How on earth you could come up with ``` ImportString[< data.pdf >, "TextMode" -> "Outlines"] ``` > Interesting code. Why do you write the replacement rule ``` FilledCurve[a__] :> FilledCurve[a] ``` that weren’t my ideas, I just found it in the mentioned link in my first post (on Stackexchange) and modified it slightly. For questions you have to ask the person who posted it there. ---

I meanwhile found the probably original source of this code: It is contained in the [documentation on `FilledCurve`](http://reference.wolfram.com/language/ref/FilledCurve.html) (the last one of the “Neat Examples”). But the question remains: **How could one find the useful option `"TextMode" -> "Outlines"` of the function `ImportString` other than by chance and what are possibly other options?** To me it seems that `ImportString` is poorly documented.
