Public Method setColumnCoordinatesScaling

static void setColumnCoordinatesScaling(int mult, int div)

Throws:

• ILCDException

Parameter	Range	Description
mult	1 ... 4096	multiplier factor for horizontal positions
div	1 ... 4096	divisor factor for horizontal positions

Scales column coordinates (horizontal positions) by a factor according to mult and div.

• Rounding errors may occur due to non-integer factors.
• This scaling is valid for all screens and viewports.
• This function can be used to migrate existing applications to another iLCD with a different display resolution.
• The parameter radius of the method Draw.drawCircle(int) is scaled with this factor.
• The display size is reported unscaled, i.e. as if both mult and div were 1 (refer to Control.getDisplaySize()).
• The scan line methods are disabled as long as any coordinates scale factor is other than 1 (see Draw.writeScanLine(int, short[]) and Draw.readScanLine(int)).
• The default value for mult and div is 1. It will be automatically set to default on startup and by the methods General.resetAll() or General.rebootPanelController().

Example

Control.setColumnCoordinatesScaling(1, 2);

This method scales subsequent horizontal positions by a factor of 0.5 (mult/div = ½).
