[Issue 126879] New: formulae can be clipped
https://bz.apache.org/ooo/show_bug.cgi?id=126879
Issue ID: 126879
Issue Type: DEFECT
Summary: formulae can be clipped
Product: Math
Version: 4.1.2
Hardware: All
OS: Windows 7
Status: UNCONFIRMED
Severity: Normal
Priority: P5 (lowest)
Component: ui
Assignee: issues@openoffice.apache.org
Reporter: feraudyh@yahoo.com
Created attachment 85361

odt file where TexMath formulae are clipped
I include an OpenOffice text file where I have attempted to insert mathematical
formulae.
Here are the settings for TexMaths I used
The output format is SVG
DPI = 600
Font size = 60
Unfortunately the bottom part of the formulae are shaved off, and this becomes
all the more apparent when I save the file as a HTML file: whatsmore the gif
files are not only clipped but much smaller than expected.

There was no "original SVG" file. The formula was generated by entering Latex
code using TexMath and pressing a button to do the conversion.
So from what you are saying, it might be the generation did not do a proper job
at creating an SVG file.
TexMaths is not designed to generate MathML as far as I know. It's an Open
Office plugin to insert formulae into the document.

So it seems, that it is not our bug. You should contact the author of the
extension.

Could you supply a copy of the typed LaTex code?

Please attach the original SVG-file. I suspect, that the part is already
missing there, at least in the included SVG-files the lower part of the
character is not complete.
Is TexMath able to export to another format, e.g. MathML?

It seems to me, that the error is in TexMath, I cannot say whether in the
extension itself or in the used library 'dvisvgm'. Do you can influence the
options used for dvisvgm from inside the extension? If yes, it should be set to
--exact.
The included svg image has a height set to 5.88339pt. Converting to cm you get
5.88339/72*2.54cm=0.207553cm. That is likely not your intended size. You should
try to use other settings in TexMath, if possible. SVG assumes 96dpi for cases
where a conversion is needed and no other agreements exist.
This height of 5.88339pt is mapped to a viewBox height of 5.88339. Therefore an
internal number of 1 is mapped to 1pt. The drawing contains a rectangle for the
overline, and a path for the character x, and a rectangle with white filling
with same x,y, width, height setting as the viewBox. When I increase the
viewBox height, then I get the whole character. So the path for the character
is correct, but the viewBox is not high enough.
