Problem description: The color and fond of the downloaded diagram is inconsistent with that of the preview.
That is because all the diagrams are designed by following the rules of PowerPoint theme font and theme color, allowing users to easily replace and change the fonts or colors of the whole presentation.
The theme font is the default font of text box. The default fonts of Office2013 and previous versions is Song (Chinese), and Calibri (English). Office2016 and later versions use Arial (both Chinese and English) as default font.
The theme fonts of all the themes in iSlide Theme Library are more commonly used:
Chinese font: Microsoft YaHei
English font: Arial
Change Theme Font
You can optimize your PowerPoint via the following ways, to keep the result consistent with the preview:
1. Change the theme font
Click and choose Slide Master in the View Tab, click and choose Font and then choose Custom Font.
2. Choose iSlide standard color
Choose [Color Library] in the [iSlide] Tab and click to apply the "iSlide Standard Color".
