Usage

From source file:Main.java

private static boolean isFontRenderContextPrintCompatible(FontRenderContext frc1, FontRenderContext frc2) {

    if (frc1 == frc2) {
        return true;
    }/*from w  w  w.j a  v a  2s  .co  m*/

    if (frc1 == null || frc2 == null) { // not supposed to happen
        return false;
    }

    if (frc1.getFractionalMetricsHint() != frc2.getFractionalMetricsHint()) {
        return false;
    }

    /* If both are identity, return true */
    if (!frc1.isTransformed() && !frc2.isTransformed()) {
        return true;
    }

    /* That's the end of the cheap tests, need to get and compare
     * the transform matrices. We don't care about the translation
     * components, so return true if they are otherwise identical.
     */
    double[] mat1 = new double[4];
    double[] mat2 = new double[4];
    frc1.getTransform().getMatrix(mat1);
    frc2.getTransform().getMatrix(mat2);
    return mat1[0] == mat2[0] && mat1[1] == mat2[1] && mat1[2] == mat2[2] && mat1[3] == mat2[3];
