Description Alex 2018-08-20 19:50:56 UTC
Description:
A canvas featuring SVG Export of text in a rotated textbox can be created.  When exported as a gif/odg this is saved corerectly. Exporting as svg causes any multiple lines of text in a rotated textbox to be displayed on top of each other.

Steps to Reproduce:
1. Create a draw canvas
2. Create a text box
3. Enter a line of text and shrink box so it wraps to multiple lines
4. Rotate box (e.g. by 90 degrees)
5. Export as svg

Actual Results:
Canvas is exported but all lines of text are displayed on top of each other.

Expected Results:
Canvas is exported with text box and looks as per the canvas in Draw


Reproducible: Always

Example output with error showing for two textboxes.

The bug only seems to happen if the angle of the textbox is >45 degrees.

Where superscript is used it creates erronious new lines for the text when the textbox is rotated (see example output).

All of the above was done using Win10 LO6.1.0.3 release
Comment 5 Regina Henschel 2018-08-21 15:48:46 UTC
It is likely the same underlying problem as in bug 119257. The position of the <tspan> elements get a shift, which does not consider, that the parent <text> element gets a "rotate" transformation and that this rotation is done after the positioning of the <tspan> elements. But I do not know, where in the code this is done, to look whether I'm right.
Comment 6 Alex 2018-08-26 10:09:12 UTC
I've retested on LO6.0.3.2 on Ubuntu 18.04 which replicates the bug.
Comment 7 Buovjaga 2018-09-20 10:52:16 UTC
Repro with file.
Already in 5.0. Older versions (4.3 tested) did not yet rotate the text but still managed to overlay it on top of itself.

Misalignment with special characters

This also happens when you insert a special character into text. The special character is misaligned, and the rest of the text after the special character is even more misaligned.

It doesn't happen if the special character is copy and pasted. For instance, this text string:

abcdθefgh

will not have the issue when pasting that into a text box, rotating it, and saving as SVG. But it will have the issue if the θ is inserted via the special character dialog.

The more the text is rotated, the more misaligned it will be.
Comment 9 Alex 2019-06-23 13:24:45 UTC
I can still reproduce the original bug in:

Version: 6.3.0.0.beta1 (x64)
Build ID: a187af327633f5f00363be5131bd21a13e0f1a7b
CPU threads: 4; OS: Windows 10.0; UI render: GL; VCL: win; 
Locale: en-GB (en_GB); UI-Language: en-GB
Calc: threaded


Also the special characters pasted (abcdθefgh) are rotated fine but inserted ones are not as per Comment 8.

Thanks for your help!

This bug is seen also with a single-line text without any special characters or super/subscripts, if the line includes different fonts.

It is present in all LibreOffice versions I have access to (on Linux)
from

LibreOffice 5.1.6.2 10m0(Build:2)

to

LibreOffice 6.4.0.3 b0a288ab3d2d4774cb44b62f04d5d28733ac6df8
