|-
| Grating Frequency        
| Defines the number of grating cycles per element's width. Zero value switches the element in the Gaussian blob mode- the full color range is used by the Gaussian function alone        
| {s:atNormal}        
| Double        
|  
|-
| Gaussian Sigma        
| Defines a standard deviation (sigma) of the Gaussian component        
| {s:atNormal}        
| Double        
|  
|-
| Grating Phase        
| Defines a shift for the grating phase, in degrees (0..360)        
| {s:atNormal}        
| Double        
|  
|-
| Grating Orientation        
| Defines the grating orientation, in degrees (0..360)        
| {s:atNormal}        
| Double        
|  
|-
| Ellipticity Ratio        
| Defines the Gaussian ellipticity- a ratio between width and height (0..1)        
| {s:atNormal}        
| Double        
|  
|-
| Trimming Threshold        
| Defines the threshold for the Gaussian component (0..1) such that the values below are not applied to the patch.        
| {s:atNormal}        
| Double        
|  
|-
| Gabor Contrast        
| Defines the normalized gabor gray contrast        
| {s:atNormal}        
| Double        
|  
|-
| Patch Shape        
| Defines a shape of the generated gabor grating        
| {s:atNormal}        
| GaborP..        
|  
|-
| colspan="5" bgcolor="#AADDDDD" | Visual Appearance
|-
| Alpha Masking        
| Defines, whether the visual content is used to create an opacity mask on the event surface. If masking is on, the content's pixel luminance (or, its inverse) defines transparency within element's viewport. The alpha masking allows, for example, create transparent holes on the event surface.        
| {s:atDesign}        
| Int32        
|  
|-
| AntiAliasing        
| if true, the rendered content will be antialiased for smoother visual appeariance. If false, rendering will be authentic to its source, e.g. a bitmap.        
| {s:atNormal}        
| Boolean        
|  
|-
| Position        
| Defines a position of the rendering viewport on the screen        
| {s:atNormal}        
| clPoint        
|  
|-
| Size        
| Defines a size of the element's rendering viewport on the screen        
| {s:atNormal}        
| clSize        
|  
|-
| Z Order        
| Indicates Z Order of the element on the given event        
| {s:atStatus}        
| Int32        
|  
|-
| Pivot Point        
| Defines alignment of the pivot point (or, element's position) relative to element's rendering area. The pivot point sets the center of element's rotation and scale directions.        
| {s:atNormal}        
| stAlig..        
|  
|-
| Visible        
| Defines whether the element is visible        
| {s:atNormal}        
| Boolean        
|  
|-
| Rotation        
| Rotation angle in degrees        
| {s:atNormal}        
| Double        
|  
|-

|-
| Transparent Color        
| The color of the original pixels of rendered content that will be set as transparent        
| {s:atNormal}        
| stColor        
|  
|-
| Transparent Tolerance        
| Tolerance ratio for choosing colors that become transparent. Zero means that effect is not applied, 1 denotes that all colors will become trasparent        
| {s:atNormal}        
| Int32        
|  
|-
| 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 dont change the original pixels        
| {s:atNormal}

| Double        
|  
|-
| Pixelation        
| Pixelation of the rendered content        
| {s:atNormal}        
| Int32        
|  
|-
| Blurring        
| The radius used in the gaussian blur of rendered content, as a pixel-based factor. The default is 0 which means no blurring.

'''Mono++ Gabor Grating Element''' renders a gabor or linear grating patch defined by a set of parameters. The patch is rendered in the in Mono++ mode (14bit gray), supported only by the ViSaGe and Bit# hardware ([http://www.crsltd.com/|Cambridge Research System]) The parameterized rendering model is adapted from a work of Elliot Freeman. <br><br>
