Element Icon Random Dots
Category: Deprecated AddIn: Visual Kernels
Creator: OkazoLab Scope: Parent event
Owns Snippets: None Usage: Stimulus screen


NameDescription                              ConstraintsTypeOn
Dots type        Type of the random dots                enRand..         
Values range        Normalized range of the random values such that 0..1 denotes the full range. The range is applied to RGB values 0..255 for the luminance and luminance-color randomizations.For the color randomization the range defines the selected section of the 360 degrees hue ring.                clRange         
Surface        Index of the random dot surface. If value is 0 then an automatic time dependent index is used. Otherwise has to be a positive integer.                Int32         
Seed map        Index of the seed map. If value is 0 then an automatic time dependent index is used. Otherwise has to be a positive integer.                Int32         
Update Surface        Runtime action. Being set to true at runtime, initiates regeneration of the random dots surface.                Boolean         
Update Seed Map        Runtime action. Being set to true at runtime, initiates regeneration of the seed map.                Boolean         
Current Surface        Actual surface index of the current surface, time-dependent or manual.                Int32         
Current Seed Map        Actual seed map index of the current seed map, time-dependent or manual.                Int32         
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.                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.                Boolean         
Position        Defines a position of the rendering viewport on the screen                clPoint         
Size        Defines a size of the element's rendering viewport on the screen                clSize         
Z Order        Indicates Z Order of the element on the given event                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.                stAlig..         
Visible        Defines whether the element is visible                Boolean         
Rotation        Rotation angle in degrees                Double         
Transparent Color        The color of the original pixels of rendered content that will be set as transparent                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                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                stColor         
Opacity        Opacity of the rendered content                Int32         
Contrast        Contrast of the rendered content                Int32         
Brightness        Brightness the rendered content                Int32         
Saturation        Saturation of the rendered content                Double         
Pixelation        Pixelation of the rendered content                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.                Int32         
Scrambling                        Double         
Scrambling Grid Size        Defines a size of the scrambling grid                clSize         
Positional Jitter
Reset Jitter Now        Runtime command that resets the positional jitter.                Boolean         
Current Jitter        Returns the current jitter                clPoint         
Jitter Range        Defines a possible range for the random jitter. The range is centered to the position of the element.                clSize         
Test Jitter        Click to test the current jitter                Boolean         
Is Enabled        If set to false the element is completely omitted when the experiment is run                Boolean         
Title        Title of the element                String         

Random Dots Element is capable of generating a 2D pixel surface where every pixel has a random luminance, color value or a combination of both. The element employs the graphics hardware and ultra-fast randomization algorithm. This element is depricated, use Random Noise Patch Element instead.
