Other array keys are optional, it can be omit.
Return false on failure.
calculateCounterClockwise()
Calculate counter clockwise degree.
protected
calculateCounterClockwise(int $value) : int
Calculate input degree for use with Imagick.
In GD 90 degrees is 270 in Imagick. This function help to make it working together very well.
So it will be...
input = output
0 = 0
1 = 359
10 = 350
90 = 270
180 = 180
270 = 90
360 = 0
Parameters
- $value : int
-
Input degrees.
Return values
int —Return opposite degrees for use with Imagick.
calculateStartXOfCenter()
Calculate startX position of center.
protected
calculateStartXOfCenter(int $objWidth, int $canvasWidth) : int
With this method, you can calculate the start x position of center (horizontal) or middle (vertical).
The purpose of this method is for internal use, do not call this method from image's driver class directly due to it can be changed in the future.
Formular: round((half of canvas) - (half of object))
Parameters

-
Destination image object size.
- $canvasWidth : int
-
Canvas size.
Return values
int —Calculated size.

applyWatermarkOpacity()
Apply forced opacity to the watermark image while preserving its alpha channel.

The opacity value from 0 (full transparent) to 100 (no transparent).
