Video Pixel Mapper

Module dedicated to direct pixel mapping for led pixels screens. See Pixel Mapping for a complete tutorial.

This module sends direct ArtNet and use networks settings of the first plot panel of Usine.

Each universe is limited to 512 channels so you with RGB pixels you can only have 170 pixels per universe. This module will send several ArtNet/DMX frames by incrementing the universe by each bloc of 512 channels.

For example if you have a 100 x 100 RGB led matrix (10000 RGB), Usine will send 10000 div 170 = 58 universes with 170 pixels and one more universe with 140 pixels (10000 mod 170 = 140).

Settings

on

Activates or deactivates the module.

video in

Video input flow(s).

show hide

Toggle visibility state of the pixel mapper window, visible/invisible.

show

Shows the pixel mapper window.

hide

Hides the pixel mapper window.

general settings

width

Width (in number of led pixels) if the mapper.

height

Height (in number of led pixels) if the mapper.

clear mapper

Clear the pixel mapper, deactivates all led pixels, resets all DMX channels.

image filename

Select the image to import to create special mapping based on a drawing. Image should be in black&white, white pixels will enabled, and black disabled.

imported image

pixels count

num total pixels

Gives the total number of led pixels, calculated as width x height

num active pixels

Gives the number of active (enabled) led pixels.

selection

To select pixels, use the [shift] key.
To unselect use [right-click]. You can zoom in/out with [mouse-wheel]. To enable a pixel use [ctrl+click] To enable and fill a pixel with the first available universe/channel use [alt+click]

enable selected

Enables selected pixels.

disable selected

Disables selected pixels.

DMX channels

Automatic DMX channels assignation. You have to select pixels you want to fill first.

start universe

Universe of the first pixel.

start index

Index in the universe of the first pixel in the range [0..512].

fill direction

Defines the fill direction.

pixel type

Determines how each color value is converted to Art-Net DMX.

  • RGB, BRG : each color is converted into 3 DMX values. Only 170 pixels can be sent per universe.
  • RGB-, BRG- : each color is converted into 4 DMX values, 3 for RGB/BRG followed by 1 filled with 0. Only 128 colors can be sent per universe.
  • -RGB, -BRG : each color is converted into 4 DMX values, 1 value filled with 0 followed by 3 for RGB/BRG. Only 128 pixels can be sent per universe.
  • ---W : each color is converted into 4 DMX values, 3 values filled with 0 followed by 1 for White. Only 128 pixels can be sent per universe.
  • W--- : each color is converted into 4 DMX values, 1 for White followed by 3 values filled with 0. Only 128 pixels can be sent per universe.
  • W : each color is converted into 1 DMX values for White. Only 512 pixels can be sent per universe.

universe size

Size of the DMX universe, only DMX 512 available in HH4.

fill DMX channels

Fills the pixels DMX channels according the settings above. Once filled, on screen, each universe is drawn with a distinct color.


each universe is drawn with a distinct color

test

Various ArtNet tests for the selected pixels.

test selected

Sends a small chaser to the selected pixels.

abort test

Abort the current test selected operation.

all ON selected

Switches ON selected pixels.

all OFF selected

Switches OFF selected pixels.

image

Implantation map.

save image

Saves the pixel mapper window as hi-def image to be used as an implantation map.

selected pixel

Visible only if a pixel is selected. Gets or sets the DMX channel information of the pixel.

enabled

The pixel is enabled.

universe

Universe number of the pixel.

channel

DMX channel of the pixel.

index

Pixel in ordex in the universe. For example with a RGB pixel type it's a number in the range [0..169].
