Inverter

public Inverter()

Construct a ColorInvert

Inverter

public Inverter(boolean autoDetect)

Construct a ColorInvert

参数:

autoDetect - color will only be inverted when the image seem to be white on black if autoDetect is true, or else color will always be inverted

方法详细资料

isAutoDetect

public boolean isAutoDetect()

Check if auto detection of white on black is enabled

返回:

enabled or not

checkWhiteOnBlack

public boolean checkWhiteOnBlack(byte[] pixels)

Check if a image seem to be white on black

参数:

pixels - the pixels array of the image

返回:

test result
