Tab size

[Joerakel]

Hi,

I have two questions. Since tabs are converted to 3 times &nbsp; (while converting to xhtml) I am trying to program the right conversion myself but for this I need to know if Word has a standard size for the <tab /> elements (like 30px or something).
-> Question one: is there a standard size for <tab /> ?

I figured out that when I want to position for example text then I need to divide the numbers which Word uses in it's xml's by about 572 to get correct distance in cm (like <w:tab w:pos="2410" w:val="left"/> -> 2410/572 = 4.21cm -> <span style="font-size: 7.0pt; position:absolute; left:4.21cm;">some text</span>) .
-> Question two: does Word generate these sizes (w:pos="2410") somehow related to my screen size or can I generally use my calculation ( /572) and the result will look the same on every screen?
(I mean if I create one Docx on my screen and another one on a bigger screen and then convert both with my calculation implemented OR does any other factor change the size of w:pos so I can't do it like that)

Info
- if I use 2410 as px it's way to large
- first question refers to sections where there is no tab size section in front like "<w:tab w:pos="24.....", just <tab />

hopefully this was not written in a tooo confusing style... I don't write in english to much

cheers Joe

Hi Joe

-> Question one: is there a standard size for <tab /> ?

This code (from src/main/java/org/docx4j/convert/out/pdf/viaXSLFO/Conversion.java) may help explain:

Question two: does Word generate these sizes (w:pos="2410")

No, those units are twips, twentieths of a point. See also https://github.com/plutext/docx4j/blob/ ... ement.java

hope this helps .. Jason
