Element that renders a single gabors grating within a rectangular area on the screen.
The gabor grating is rendered with a set of parameters that define its kernel structure. The rendering process relays on a computer graphic hardware and therefore is very fast: aprox 50 ms per a gabor grating of 800x600 pixels size.

| VISUAL APPEARANCE |
| Alpha Masking | Defines whether the visual content rendered by this element will be used as an opacity mask which is applied onto the given event surface. The active opacity mask allows one to expose pixels of the parent event surface through a solid background of the given event. If the value is true, the darker pixels of the content will make more transparent holes on the entire event surface. | | Boolean | |
| AntiAliasing | If true, the rendered content will be anti-aliased for smoother visual appearance. If false, rendering will be authentic to its source, e.g. a bitmap. | | Boolean | |
| Position | Defines the position of the element viewport on the screen. The position can be set in any of three coordinate systems: a) pixels, b) polar, c) central. | | clPoint | |
| Size | Defines the size of the element viewport on the screen. The size can be set in any of three coordinate systems: a) pixels, b) visual degrees, c) 'relative-to-screen' size. | | clSize | |
| Z Order | Indicates the current depth order of the element viewport on the surface of the parent event. The greatest number corresponds to the top position. The order can be changed by moving the element up and down in the element list. | | Int32 | |
| Pivot Point | Defines the pivot point (coordinate and the rotation centers) within the element viewport. | | stAlignment or Int32 | |
| Visible | Defines whether the element is currently visible on the event surface. The property is convenient for switching visual content on and off. | | Boolean | |
| Rotation | Defines the rotation angle (in degrees) of element viewport relative to the its pivot point. | | Double in the range 0..360 | |
| EFFECTS |
| Transparent Color | The color of the original pixels of rendered content that will be set as transparent. | | stColor | |
| Transparency Tolerance | Tolerance ratio for choosing colors that become transparent. Zero means that effect is not applied, 1 denotes that all colors will become trasparent. | | Int32, range (0..100) | |
| Color Mask | Produces a multiplicative combination of the original pixels and the selected mask color (except the alpha channel). The effect emulates a look through a colored glass. White or transparent mask color doesn't change the original pixels. | | stColor | |
| Opacity | Opacity of the rendered content. | | Int32, range (0..100) | |
| Contrast | Contrast of the rendered content. | | Int32, range (-100..100) | |
| Brightness | Defines the brighness of the rendered content. | | Int32, range (-100..100) | |
| Saturation | Saturation of the rendered content. | | Double | |
| Pixelation | Defines the pixel scale of the rendering. | | Int32, range (0..100) | |
| Blurring | The radius used in the gaussian blur of rendered content, as a pixel-based factor. The default is 0 which means no blurring. | | Int32 | |
| POSITIONAL JITTER |
| Reset Jitter | Set to true at runtime to reset the current positional jitter. | | Boolean, set true for action | |
| Current Jitter | Jitter range, in pixels (non inclusive). | . | clSize | |
| Jitter Range | Jitter range, centered at the original position of the element. | . | clSize | |
