The grid filter property is used to activate filter effects on a layout block. Filter effects on a block also affect all associated block items.
?> When discussing grid layouts content-within-blocks are referred to as block items.
The following basic syntax is used to activate a filter on a layout block:
[drag=width height, drop=x y, filter=effect]
Where the effect option on the filter= property can take one of the following filter types:
- blur
- bright
- contrast
- grayscale
- hue
- invert
- saturate
- sepia
The following sample slide screenshot demonstrates filter effects on sample blocks:
Note this sample slide demonstrates different filter effects on each layout block and also filters activated directly on some of the individual images using Image Widget Syntax.
