Returns​

void

Implementation of​

AfterViewInit.ngAfterViewInit

Properties​

autoShrink?​

optional autoShrink: boolean

Defaults to true, and instructs the grid that if the grid has grown beyond any minimum value set in either axis, if the content bounds subsequently shrink in that axis below the minimum, the grid should shrink back to the minimum. If you set this to false the grid will never shrink back to its minimum values once they have been exceeded.

Input​

dotRadius?​

optional dotRadius: number

The radius for dots representing grid positions (when gridType id GridTypes.dotted). Defaults to 2.

Input​

grid?​

optional grid: Grid

The grid to use. This is optional; if you do not supply one the background will attempt to read the grid definition from the Surface. If that is also not set then a default grid of 50x50 pixels will be used.

Input​

gridType?​

optional gridType: GridType

Type of grid - lines or dots. Defaults to lines.

Input​

maxHeight?​

optional maxHeight: number

The maximum height for the grid. The value you provided is divided by 2 and then the grid is guaranteed to never exceed the range of (-maxHeight / 2) - (maxHeight / 2). maxHeight takes precedence over minHeight.

Input​

maxWidth?​

optional maxWidth: number

The maximum width for the grid. The value you provided is divided by 2 and then the grid is guaranteed to never exceed the range of (-maxWidth / 2) - (maxWidth / 2). maxWidth takes precedence over minWidth.

Input​

minHeight?​

optional minHeight: number

The minimum height for the grid. The value you provided is divided by 2 and then the grid is guaranteed to always at least span the range of (-minHeight / 2) - (minHeight / 2). Defaults to 20 000.

Input​

minWidth?​

optional minWidth: number

The minimum width for the grid. The value you provided is divided by 2 and then the grid is guaranteed to always at least span the range of (-minWidth / 2) - (minWidth / 2). Defaults to 20 000.

Input​

showBorder?​

optional showBorder: boolean

Whether or not to show a thick border around the entire background. Defaults to false.

Input​

showTickMarks?​

optional showTickMarks: boolean

Defaults to false. If true, the grid will also draw tick marks between the grid lines.

Input​

tickDotRadius?​

optional tickDotRadius: number

The radius for dots representing grid tick marks (when gridType id GridTypes.dotted). Defaults to 1.

Input​

tickMarksPerCell?​

optional tickMarksPerCell: number

Number of tick marks to draw per cell. Defaults to 2.

Input​

visible?​

optional visible: boolean

Whether or not the background is initially visible. Defaults to true.
