@forasposeissues,

Thank you for confirming.

It is strange that you are still experiencing the issue, but I was unable to reproduce the problem you mentioned. Nevertheless, we will thoroughly evaluate your issue and provide you with updates.

@forasposeissues,

Upon further evaluation of your issue, it appears that there is a problem with accessing fonts on your end. Our analysis of your PDF revealed that the fonts Arial-BoldMT, ArialMT, and CambriaMath (Regular and Bold) are missing. Please ensure that these fonts are installed and accessible in the default fonts folder directory on your end.

24

Thanks for update.

Could you please help to share font which you mentioned in the above thread.
We will install the font and place the font in the font directory and test it.

Appreciate for help.

Thanks

Summarizing issue again.

  • User: While converting the PPT document to pdf. We can see that symbol & character are not coming clear with pdf file.

  • Aspose: Aspose provide solution to upgrade aspose slides to 24.4 version

  • User: First issue was resolve. But, “¥฿” these two symbol got overlapped when ppt is converted into pdf.

  • Aspose: aspose mentioned that “on further evaluation of your issue, it appears that there is a problem with accessing fonts on your end. Our analysis of your PDF revealed that the fonts Arial-BoldMT, ArialMT, and CambriaMath (Regular and Bold) are missing. Please ensure that these fonts are installed and accessible in the default fonts folder directory on your end.”

  • User: But, when we checked the ppt document then “¥” and “฿” symbol has “Citi Sans Condensed” font applied. Ideally, it should convert into PDF without issue.

  • Aspose: But, aspose mentioned in his ticket (SLIDESJAVA-39351) that they have improved the rendering of symbols for specific fonts in PDF documents. Please note that for the correct display of the Thai Baht currency symbol (฿), it is necessary to install the Angsana New font or load it using FontsLoader.LoadExternalFonts logic.But, PowerPoint automatically downloads this font if it is not installed on the system when opening a presentation containing this symbol. Additionally, we have added a new option in PdfOptions.RasterizeUnsupportedFontStyles (bool), which allows rasterizing text into a bitmap and saving it in the PDF document as images if the font does not support the bold style. This approach is used in PowerPoint while converting presentations to PDF for Citi Sans Condensed (Bold) font, ensuring clearer characters and symbols.

  • User: We have upgraded aspose version 24.4 and used PdfOptions.RasterizeUnsupportedFontStyles(true). But, Still “¥฿” these two symbol got overlapped when ppt is converted into pdf(as per latest response it should be picked up as image)

Team please help us for given above issue.

Appreciate for help.
