Hi,
We use java.awt.Font in general that is used in Java application in the common way. To measure the width/height of cells’ content, we use java.awt.Font and java.awt.FontMetrics as following:
java.awt.Font font = new java.awt.Font(name, style, size);
new JLabel().getFontMetrics(font);
...
Please try this simple code (with the fonts used in your template file) in your environment without any reference to Aspose.Cells. If it can work, then auto-fit function should work fine too.
Thank you.
