|-
| Grab Blob Now        
| Grabs the mean color and size of a blob inside of the current element area. The grabbed values are assigned to the Base Color and Base Size properties

| {s:atNormal}        
| Double        
|  
|-
| Saturation Tolerance        
| Defines the saturation tolerance (%) in blob detection relatively to saturation of the base color

|  
|-
| Detection Pace        
| Defines the minimal pace (in ms) of the auto-detection passes in response to visual changes in the parent event. If the visual changes are frequent, e.g. due to playing movie, the pace should not be less than the detection processing time.        
| {s:atNormal}        
| Double        
|  
|-
| Test Detection Now

| Boolean        
|  
|-
| 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

| 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        
|  
|-
| colspan="5" bgcolor="#AADDDDD" | Effects
|-
| 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

'''Color Blob Tracker Element''' automatically tracks an arbitrary color object on the event surface. The tracking process returns the object position and size over time. The results can be used in runtime, e.g. to move the ROI area, or recorded as a time-line trajectory.<br><br>
