Color Picker

From RealMotion Wiki

Image Processing/Operations/Color Picker

Returns the color of a pixel at a given coordinates. ​

Description

The Color Picker box returns the color of a pixel at a given 2D (x,y) screen coordinate. Color may be outputted as a float4 or directly into a texture buffer.

General Use Case: The box is used in projects to get the value of a pixel while changing coordinates dynamically.

Inputs

Coordinates Float2 Receives the coordinates where to sample.
Texture 2D Texture Receives the texture to sample.

Outputs

Color Float4 Outputs the color value of the selected pixels.
Texture 2D Render Target Outputs the color value of the selected pixels in a created texture buffer.

Parameters

General

Output Type String Chooses the output type between the Color Value and a texture set to that color.

Channel Settings

Format String Sets the format of the outputted texture. RGBA 8 bits is the common format. RGBA 16 bits allows negative vector calculation and is mostly used for simulation. RGBA 32 bits allows high precision but may negatively affect the FPS and the Grayscale has only the Red component.
Format Components String Sets the Components used for the outputted texture.
Format Component Bit Depth String Sets the Bit Depth of the outputted texture. 8 bits is the common format, 16 bits allow negative vector calculation and is mostly used for simulation, 32 bits allow high precision but may negatively affect the FPS.
Format Component Type String Sets the pixels value type depending on the Bit Depth.

Canvas Settings

Resolution Mode String Sets the Resolution Mode. Canvas uses the project configuration settings, Custom uses local setting resolution not shared with other box and Project Aspect Ratio uses the project aspect ratio and proportionally scales the height and width. The parameter chooses the reference Canvas setting the resolution of the outputted texture.
Canvas 2D ResolutionRef Chooses the reference Canvas and sets the resolution of the outputted texture.
Maximum Resolution Int Sets the maximal resolution of the X-axis and calculates the resolution of the Y-axis based on the aspect ratio of the Content Canvas.
Lock Aspect Ratio Toggle Locks the Aspect Ratio for Custom resolution.
Aspect Ratio 2D ResolutionRef Chooses the reference Canvas for the aspect ratio.
Size XY Int2 Sets the size in pixels of the outputted texture.
