Properties

EXACT_FIT

The entire application is visible in the specified area without trying to preserve the original aspect ratio.
Distortion can occur, and the application may appear stretched or compressed.

NO_BORDER

The entire application fills the specified area, without distortion but possibly with some cropping,
while maintaining the original aspect ratio of the application.

SHOW_ALL

The entire application is visible in the specified area without distortion while maintaining the original
aspect ratio of the application. Borders can appear on two sides of the application.

FIXED_HEIGHT

The application takes the height of the design resolution size and modifies the width of the internal
canvas so that it fits the aspect ratio of the device
no distortion will occur however you must make sure your application works on different
aspect ratios

FIXED_WIDTH

The application takes the width of the design resolution size and modifies the height of the internal
canvas so that it fits the aspect ratio of the device
no distortion will occur however you must make sure your application works on different
aspect ratios

UNKNOWN

Unknow policy

Methods

constructor

Parameters

• containerStg ContainerStrategy The container strategy
• contentStg ContentStrategy The content strategy

preApply

Manipulation before applying the resolution policy

Parameters

• view View The target view

apply

Function to apply this resolution policy The return value is {scale: [scaleX, scaleY], viewport: {cc.Rect}}, The target view can then apply these value to itself, it's preferred not to modify directly its private variables

Parameters

• view View The target view
• designedResolution Size The user defined design resolution

postApply

Manipulation after appyling the strategy

Parameters

• view View The target view

setContainerStrategy

Setup the container's scale strategy

Parameters

• containerStg ContainerStrategy

setContentStrategy

Setup the content's scale strategy

Parameters

• contentStg ContentStrategy
