Video Pixel Mapper

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

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

target plot

Sets the target plot for the pixel mapper. The pixel mapper will take the settings of the target plot (Artnet IP address, etc.).

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.

drawing example

imported image

pixels general

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.

pixel type override

Forces the pixel type to a global value. Normally, the pixel type is set individually for each pixel with pixel type option (see bellow).

the override pixel type must have the same number of DMX channels than all pixels of the pixel-mapper. For example, if you have RGB 3 bytes pixels on the pixel-mapper, you can't override it to RGBW 4 bytes. In those cases, you might have unpredictable results.

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 3 bytes : each color is converted into 3 DMX for RGB values. Only 170 pixels can be sent per universe.
• BRG 3 bytes : each color is converted into 3 DMX for BRG values. Only 170 pixels can be sent per universe.
• RGB- 4 bytes : each color is converted into 4 DMX values, 3 for RGB followed by 1 filled with 0. Only 128 colors can be sent per universe.
• -RGB 4 bytes : each color is converted into 4 DMX values, 1 value filled with 0 followed by 3 for RGB. Only 128 pixels can be sent per universe.
• -BRG 4 bytes : each color is converted into 4 DMX values, 1 value filled with 0 followed by 3 for BRG. Only 128 pixels can be sent per universe.
• BRG- 4 bytes : each color is converted into 4 DMX values, 3 for BRG followed by 1 filled with 0. Only 128 colors can be sent per universe.
• RBG 3 bytes : each color is converted into 3 DMX for RBG values. Only 170 pixels can be sent per universe.
• BGR 3 bytes : each color is converted into 3 DMX for BGR values. Only 170 pixels can be sent per universe.
• GBR 3 bytes : each color is converted into 3 DMX for GBR values. Only 170 pixels can be sent per universe.
• GRB 3 bytes : each color is converted into 3 DMX for GRB values. Only 170 pixels can be sent per universe.
• RGBW 4 bytes : each color is converted into 4 DMX RGB + WHITE. Only 128 pixels can be sent per universe.
• WRGB 4 bytes : each color is converted into 4 DMX WHITE + RGB. Only 128 pixels can be sent per universe.
• --W 3 bytes : 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 4 bytes : 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--- 4 bytes : 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 1 bytes : each color is converted into 1 DMX value for WHITE. Only 512 pixels can be sent per universe.
• WWWW 4 bytes : each color is converted into 4 DMX values for WHITE. Only 128 pixels can be sent per universe.
• WWW 3 bytes : each color is converted into 3 DMX values for WHITE. Only 170 pixels can be sent per universe.
• WW 2 bytes : each color is converted into 2 DMX values for WHITE. Only 256 pixels can be sent per universe.
• GRBW 4 bytes : each color is converted into 4 DMX GRB + WHITE. Only 128 pixels can be sent per universe.
• WGRB 4 bytes : each color is converted into 4 DMX WHITE + GRB. Only 128 pixels can be sent per universe.
• RGBWW 5 bytes : each color is converted into 5 DMX values for RGB + WHITE + WHITE. Only 102 pixels can be sent per universe.
• WWRGB 5 bytes : each color is converted into 5 DMX values for WHITE + WHITE + RGB. Only 102 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
