Example 24 with FontRenderContext

use of java.awt.font.FontRenderContext in project poi by apache.

the class BaseTestBugzillaIssues method computeCellWidthManually.

// FIXME: this function is a self-fulfilling prophecy: this test will always pass as long
// as the code-under-test and the testcase code are written the same way (have the same bugs). 
private double computeCellWidthManually(Cell cell0, Font font) {
    final FontRenderContext fontRenderContext = new FontRenderContext(null, true, true);
    RichTextString rt = cell0.getRichStringCellValue();
