Field Detail

DEFAULT_CHARACTER_WIDTH	back to summary
public static final float DEFAULT_CHARACTER_WIDTH Width of one "standard character" of the default font in pixels. Same for Calibri and Arial. "Standard character" defined as the widest digit character in the given font. Copied from XSSFWorkbook, since that isn't available here. Note this is only valid for workbooks using the default Excel font. Would be nice to eventually support arbitrary document default fonts.
