support text rotation

We need to be able to rotate certain headers in our tables when @outputclass=”rotated” is specified.

In our xsl:fo, we support this with:

Code: Select all

<xsl:when test="@outputclass='rotated'">
<fo:block-container reference-orientation="90" inline-progression-dimension="1in">
<fo:block xsl:use-attribute-sets="thead.row.entry__content">
<xsl:apply-templates select="." mode="ancestor-start-flag"/>
<xsl:call-template name="processEntryContent"/>
<xsl:apply-templates select="." mode="ancestor-end-flag"/>
</fo:block>
</fo:block-container>
</xsl:when>
Please add equivalent support in Chemistry PDF CSS.

Hi Scott,

I already replied to this on the email you sent on our support email address, but I will also paste my reply on this thread.
We only support transform: rotate(90deg); / rotate(-90deg); rules.

However, you could either rotate the whole page containing the table or rotate the table in the page.
For guidance, you should take a look at How to Deal With Wide Tables - Page Rotation and Rotating tables sections from the DCPP / Chemistry User-Guides respectively. Please make sure you pay attention also to the Notes on the indicated User-Guide pages.
Regads,
Costin

I saw the reply, but this request is to support the text rotation within a header cell, not rotate the entire table. I still haven't been able to get this to work:

Code: Select all

*[class ~= "rotated"] {
transform: rotate(90deg) !important;
}

Hi Scott,

As a remark you should rotate the text the other way around:

Code: Select all

*[class ~= "rotated"] {
transform: rotate(-90deg) !important;
}
But somehow indeed this does not work if you mark the "<entry>" with "outputclass='rotate'". We'll try to fix it on our side.
In the meantime if you can add a paragraph in each <entry> that you rotate like:

Code: Select all

<entry outputclass="rotated"><p>aaa</p></entry>
you could re-write your CSS like this:

Code: Select all

*[class ~= "rotated"] > * {
transform: rotate(-90deg) !important;
}
and this should work.

Regards,
Radu

Adding the <p> around the table header text and using the style provided works! That said, the table header is not tall enough, so the text overruns. How can I address the table row height?

To address the height issue, I found a similar post on StackOverflow. I still can't get the text to align at the bottom of the cell now:

Code: Select all

*[outputclass ~= "rotated"] > * {
display: block;
transform: rotate(-90deg) translate(-100%) !important;
text-align: left !important;
margin-left: 0 !important;
margin-top: -10%;
vertical-align:bottom;
}

tr > *[outputclass ~= "rotated"] {
padding: 10% 0;
height: 0;
vertical-align:bottom;
}

The padding was the issue. I fixed as follows:

Code: Select all

*[outputclass ~= "rotated"] > * {
display: block;
transform: rotate(-90deg) translate(-100%) !important;
text-align: left !important;
margin-top: -10%;
margin-bottom: 0;
vertical-align:bottom;
white-space: nowrap;
}

tr > *[outputclass ~= "rotated"] {
padding-top: 10%;
height: 0;
vertical-align:bottom;
text-align: left !important;
}

Is it possible to rotate text in the table cell in pdf-css transformation scenario?

Thanks, this works somehow. But I cannot figure out how the cell height is calculated. As I understand, code "padding-top: 10%;" is responsible for that. But 10% of what? It does not depend on the cell content.

The recommended way is to set a width and optionally a height to rotated block. Negative paddings or margins should be used as last resort.

If you are using the HTML based transformation try:

Code: Select all


*[outputclass ~= "rotated"] > *[class ~= "topic/p"] {
display: block;
transform: rotate(-90deg) !important;
text-align: left !important;

padding:0;
margin:0;

vertical-align:bottom;
white-space: nowrap;
background-color:cyan;
width:50px;
height:80px;
}

tr > *[outputclass ~= "rotated"] {
background-color:yellow;
padding:0;
}
A DITA sample:

Code: Select all


<table frame="all"
id="simpletable_hfw_z5d_gfb" rowsep="1" colsep="1" >
<tgroup cols="2" >
<colspec colname="c1" colwidth="1*" rowsep="1"/>
<colspec colname="c2" colwidth="1*" colsep="1"/>
<thead>
<row>
<entry>Normal</entry>
<entry>Normal</entry>
</row>
</thead>
<tbody>
<row>
<entry outputclass="rotated">
<p>Rotated</p>
</entry>
<entry>Normal</entry>
</row>
<row>
<entry>Normal</entry>
<entry>Normal</entry>
</row>
<row>
<entry>Normal</entry>
<entry>Normal</entry>
</row>
</tbody>
</tgroup>
</table>
Many regards,
Dan
