        public boolean isPrint()

      • setPrint

        public void setPrint​(boolean print)

      • setFontScalingFactor

        public void setFontScalingFactor​(float scaling)
        Sets the scaling factor used by incrementFontSize() and decrementFontSize()--both scale the font up or down by this scaling factor. The scaling roughly modifies the font size as a multiplier or divisor. A scaling factor of 1.2 applied against a font size of 10pt results in a scaled font of 12pt. The default scaling factor is 1.2F.

      • incrementFontSize

        public void incrementFontSize()
        Increments all rendered fonts on the current document by the current scaling factor for the panel. Scaling applies cumulatively, which means that multiple calls to this method scale fonts larger and larger by applying the current scaling factor against itself. You can modify the scaling factor by setFontScalingFactor(float), and reset to the document's specified font size with resetFontSize().

      • resetFontSize

        public void resetFontSize()
        Resets all rendered fonts on the current document to the font size specified in the document's styling instructions.

      • decrementFontSize

        public void decrementFontSize()
        Decrements all rendered fonts on the current document by the current scaling factor for the panel. Scaling applies cumulatively, which means that multiple calls to this method scale fonts smaller and smaller by applying the current scaling factor against itself. You can modify the scaling factor by setFontScalingFactor(float), and reset to the document's specified font size with resetFontSize().

      • getMaxFontScale

        public float getMaxFontScale()
        Returns the maximum font scaling that may be applied, e.g. 3 times assigned font size.

      • getMinFontScale

        public float getMinFontScale()
        Returns the minimum font scaling that may be applied, e.g. 0.5 times assigned font size.

      • setMaxFontScale

        public void setMaxFontScale​(float f)
        Sets the maximum font scaling that may be applied, e.g. 3 times assigned font size. Calling incrementFontSize() after this scale has been reached doesn't have an effect.

      • setMinFontScale

        public void setMinFontScale​(float f)
        Sets the minimum font scaling that may be applied, e.g. 3 times assigned font size. Calling decrementFontSize() after this scale has been reached doesn't have an effect.
