TImageEnView.LayersSizeAll

Declaration

procedure LayersSizeAll(HorzSizing, VertSizing: Double; bSelectedOnly: Boolean = False; bFixSizes: Boolean = False; ScalePosition: Boolean = False);

Description

Scales the Width and Height values for all layers (or just selected if bSelectedOnly = True). HorzSizing and VertSizing are percentage values, so 2 will double the layer size, and 0.5 will halve it.
If bFixSizes = True, then LayersFixSizes is called to resample the layer to the new sizes.
If ScalePosition is True, then PosX and PosY are scaled to keep their position relative to other layers (best if also scaling the background layer). If False the layer is centered after scaling (best when only scaling some layers).

Note: To size by pixels rather than scale, see LayersRepositionAll

Examples

// Halve the size of all layers
ImageEnView1.LayersSizeAll( 0.5, 0.5, False, False, True );

// Increase the size of selected layers by 25%
ImageEnView1.LayersSizeAll( 1.25, 1.25, True );
