The Math symbol-Integral sign is not being displayed in the pdf preview window #33
Comments

Sign SUM not being displayed as well as an integral sign |
|
I was checking and it seems to be a bug in the PDPage.convertToImage so I reported this: https://issues.apache.org/jira/browse/PDFBOX-2915 |

Also, while debugging made this change: --- a/OpenLaTeXStudio/EditorModule/src/latexstudio/editor/pdf/PDFPreviewRefresher.java

It looks like this has been fixed in PDFBox 2.0.0 which is now released https://pdfbox.apache.org/index.html |
|
I've updated the pdfbox version we use to 2.0.0, however there are some issues. When scaling the image up, at some point the renderer throws OutOfMemoryError. If anyone is interested in trying to resolve that problem, the progress is on dev/new-pdfbox branch. |
|
Looks like the out of memory error is tied to the scaling not working. The returned image expands in size until it's too large, not sure of the actual implementation. |
|
Looks like the old method for zooming had issues as well, still ongoing in order to generate a fix for the issue. |
|
Should be fixed by #140 |
Description:
The PDF preview window doesn't display the integral sign. When the tex file generates a PDF, the integral sign is displayed.
Steps to Recreate:
\begin{equation_}
x = \int^0_5 y^2 +7
\end{equation_}
Expected Result:
The pdf preview window will display the whole equation including the integral sign
Actual Result:
The pdf preview window did not display the integral sign to complete the equation
Screenshot:
Windows 7
In the generated PDF the integral sign is displayed.
