Overview
The boundaries for the view.
The area enclosed by the boundaries is the viewable area. Within the viewable area, the user can flexibly move or zoom the view. When the user tries to move the view beyond the viewable area, the SDK automatically drags the view back into the viewable area.
– initWithCenter:minContent:maxContent:
Sets the center of the viewable area and initializes the WhiteCameraBound object.
- (instancetype)initWithCenter:(CGPoint)visionCenter minContent:(WhiteContentModeConfig *)minConfig maxContent:(WhiteContentModeConfig *)maxConfigParameters
visionCenter |
The coordinate of the center in the viewable area in the world coordinate system (taking the center of the initial whiteboard as the origin). |
|---|---|
minConfig |
The minimum scale factor of the viewable area. |
maxConfig |
The maximum scale factor of the viewable area. |
Return Value
An initialized WhiteCameraBound object.
Declared In
WhiteCameraBound.h
– initWithFrame:minContent:maxContent:
Sets the frame of the viewable area and initializes the WhiteCameraBound object.
- (instancetype)initWithFrame:(CGRect)visionFrame minContent:(WhiteContentModeConfig *)minConfig maxContent:(WhiteContentModeConfig *)maxConfigParameters
visionFrame |
The frame, that is, the value of (width * height) of the viewable area。 |
|---|---|
minConfig |
The minimum frame ( |
maxConfig |
The maximum frame ( |
Return Value
An initialized WhiteCameraBound object.
