Retrieving of layout shape's font height

[AdamShakhabov]

Hello. I am trying to get a font height from one of layout shapes and getting NaN every time.

Here is an XML shape description:

Code: Select all

-<p:sp>
-<p:nvSpPr>
<p:cNvPr name="Text Placeholder 10" id="11"/>
-<p:cNvSpPr>
<a:spLocks noGrp="1"/>
</p:cNvSpPr>
-<p:nvPr>
<p:ph type="body" sz="quarter" hasCustomPrompt="1" idx="10"/>
</p:nvPr>
</p:nvSpPr>
-<p:spPr>
-<a:xfrm>
<a:off y="5867400" x="577850"/>
<a:ext cy="762000" cx="5200650"/>
</a:xfrm>
</p:spPr>
-<p:txBody>
<a:bodyPr anchor="b"/>
-<a:lstStyle>
-<a:lvl1pPr>
-<a:defRPr sz="900">
<a:latin charset="0" pitchFamily="34" typeface="Arial"/>
<a:cs charset="0" pitchFamily="34" typeface="Arial"/>
</a:defRPr>
</a:lvl1pPr>
</a:lstStyle>


So I am trying to reach the line:

Code: Select all

-<a:defRPr sz="900">

How and can I do that?

Dear Adam,

Thank your for contacting us.
Kindly note that the <a:defRPr sz="900"> represents the default font size of text. Sorry for the fact that our Spire.Presentation does not support getting the default font size at present. That's the reason why you get NAN. We have already added it as a new feature into our upgrade list. Once it is achieved, I will inform you. Apologize for the inconvenience. In addition, could you please share us with your testing PowerPoint file? So that we can better test your case when the feature is done. Thanks in advance.

Sincerely,
Nina

Hi, about when it is going to be implemented?

[Nina.Tang]

Hi,

Sorry I can't provide an accurate timeline about when the feature could be implemented at this moment. Our Dev team is working on the feature now and I have requested our Dev team to share any possible estimated time at their earliest. I will keep you informed once it is finished or I get any feedback from our Dev team. Thanks for your cooperation.

Sincerely,

Dear Adam,

Glad to inform you that the default font size could be obtained now, welcome to download the release Spire.Presentation Pack Version:4.7 and use the following code to have a test.

Code: Select all

Presentation ppt = new Presentation();
ppt.LoadFromFile(filepath);
var autoShape = (IAutoShape)ppt.Slides[0].Shapes[0];
var fontHeight = autoShape.TextFrame.Paragraphs[0].TextRanges[0].FontHeight;
