Aspose.Cells for Android logo

We are pleased to announce the release of Aspose.Cells for Android 8.1.2. The new version contains many useful enhancements. It also includes several fixes and other improvements. Below, we list the major features and enhancements in this month’s release.

Getting Warnings for Font Substitution

Aspose.Cells APIs generally use TrueType Fonts (TTFs) when a task involves rendering spreadsheets to images or portable formats such as PDF. Aspose.Cells detects which TTFs are required by scanning the spreadsheet styles and tries to find the required fonts on the machine where conversion is taking place. There could be situations when the required TTFs are not available. In such cases, Aspose.Cells substitutes the required font with a similar available one.

With this release, Aspose.Cells provides the means to receive warnings if a font substitution has occurred during the spreadsheet rendering process. This mechanism is available through a set of classes, interfaces and properties that have been added with version 8.1.2.

public class WarningCallback implements IWarningCallback {

    @Override
    public void warning(WarningInfo info) {
        if(info.getWarningType() == WarningType.FONT_SUBSTITUTION)
        {
            System.out.println("WARNING INFO: " + info.getDescription());
        }
    }
}
