Table row height incorrect after changing font

[John.Hunt]

Hi,
I'm creating a PowerPoint table row by row and inserting text but having trouble laying out shapes in the right positions. The row heights and OffsetY positions are incorrect when adding text in non-standard fonts. It appears as if the row heights are calculated using standard fonts like 'Calibri', but if text is inserted into a table cell in a different font, say, Century, the row height and OffsetY positions don't reflect the fact that the text now wraps across more rows.

An example is attached - the first slide uses Calibri font and the green triangles are aligned with the table rows. The second slide uses Century font and the green triangles (which are positioned using OffsetY) are in the wrong place.

Is there any way in which I can get the row heights to reflect the font being used?
Thanks,
John

Hello,

Thanks for your inquiry.
I used the following code to get the row height and offsetY, indeed found that there was no difference between different fonts. I will post this issue to our Dev team for further investigation, if there is any news, I will inform you. Sorry for the inconvenience caused.

Code: Select all

double heih = table[0, 0].Height;
double y1 = table[0, 0].OffsetY;

Hi Annika,

Many thanks for the reply and for taking the trouble to look at this. In case it's helpful, here is sample code and a template that demonstrates the issue. I've attached both an empty template and the template after population by the code below. The triangle is misplaced in the example using Century font, but if the font is changed to 'Calibri' the triangle is correctly aligned to the top of the next row.

Dim projectTable As Spire.Presentation.ITable = ppt.Slides(0).Shapes(0)

Dim dummytext As String = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam dapibus sem eget ante auctor rutrum. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. Maecenas volutpat justo et justo tristique hendrerit. Donec in magna ut turpis vehicula feugiat. Aliquam luctus lorem purus, ut volutpat felis malesuada dictum. Donec id ante urna. Vivamus id ligula eros. Donec vel ex malesuada, aliquam enim in, posuere massa. In hac habitasse platea dictumst. Vivamus et elementum mi. Praesent luctus eros consequat magna suscipit, et accumsan dui sagittis. Fusce pellentesque magna nulla, vel congue sem varius non. Vivamus justo sapien, rutrum aliquam feugiat eget, mattis in est. Suspendisse congue facilisis purus vitae fringilla. Curabitur dignissim libero a elementum tristique. Nam facilisis, justo et ullamcorper ornare, risus nulla pulvinar enim, ac tristique nisl lectus eget erat. Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia curae; Nulla venenatis enim in fringilla interdum. Vivamus malesuada quis dolor quis pulvinar. Proin tempus vel risus eu sollicitudin. Nam augue lorem, tincidunt sit amet metus a, pretium euismod nisi."

projectTable(1, 1).TextFrame.TextRange.Text = dummytext
projectTable(1, 1).TextFrame.TextRange.LatinFont = New TextFont("Century")

Dim RAGTriangle = ppt.Slides(0).Shapes.AppendShape(ShapeType.RightTriangle, New RectangleF(projectTable.Frame.Left + projectTable(0, 2).OffsetX, projectTable.Frame.Top + projectTable(0, 2).OffsetY, 24, 24))
RAGTriangle.Rotation = 90

Hello,

Thanks for your detailed information.
I tested your case with our latest Spire.Presentation (Spire.Presentation Pack Hotfix Version:6.9.2), but didn't find the position of triangle was incorrect. Here I uploaded my outputs for your reference. If you were not using the latest version, please first give it a try. If the issue still happens after trying, please provide your testing environment, such as OS info (E.g. Windows7, 64bit), Region setting (E.g. China, Chinese) as well as your app type (E.g. Console app, Net Framework 4.7.2) for further information. Looking forward to your reply.

Best Regards,

Thank you, it's very helpful to see your outputs and learn that this works correctly in your environment. I've tried on a second system and it's working there for me as well, so this does look like a problem with a specific environment. I suspect the issue is that the font isn't correctly installed on the production webserver. Please consider this resolved and thank you for your assistance.

[Edit in case anyone else is struggling with this - solved by embedding the font in the Powerpoint template]
