HIGHLIGHTS

• 30 function BLEND node -- subtract, multiply and overlay like the best
• Vector support for 2, 3, 4 size tuples of integer or float type
• Specific RGB/RGBA color vector support that provides a color picker
• All Image inputs support RGBA, RGB or pure MASK input
• Full Text generation support using installed system fonts
• Basic parametric shape (Circle, Square, Polygon) generator~~
• COLOR BLIND check support
• COLOR MATCH against existing images or create a custom LUT
• Generate COLOR THEORY spreads from an existing image
• COLOR MEANS to generate palettes for existing images to keep other images in the same tonal ranges
• PIXEL SPLIT separate the channels of an image to manipulate and PIXEL MERGE them back together
• STACK a series of images into a new single image vertically, horizontally or in a grid
• Or FLATTEN a batch of images into a single image with each image subsequently added on top (slap comp)
• VALUE Node has conversion support for all ComfyUI types and some 3rd party types (2DCoords, Mixlab Layers)
• LERP node to linear interpolate all ComfyUI and Jovimetrix value types
• Automatic conversion of Mixlab Layer types into Image types
• Generic ARRAY that can Merge, Split, Select, Slice or Randomize a list of ANY type
• STRINGER node to perform specific string manipulation operations: Split, Join, Replace, Slice.
• A QUEUE Node that supports recursing directories, filtering multiple file types and batch loading
• Use the OP UNARY and OP BINARY nodes to perform single and double type functions across all ComfyUI and Jovimetrix value types
• Manipulate vectors with the SWIZZLE node to swap their XYZW positions
• DELAY execution at certain parts in a workflow, with or without a timeout
• Generate curve data with the TICK and WAVE GEN nodes

<br> <h1>AS OF VERSION 2.0.0, THESE NODES HAVE MIGRATED TO OTHER, SMALLER PACKAGES</h1>

Migrated to GLSL SHADERS

~~* GLSL shader support~~ ~~* * GLSL Node provides raw access to Vertex and Fragment shaders~~ ~~* * Dynamic GLSL dynamically convert existing GLSL scripts file into ComfyUI nodes at runtime~~ ~~* * Over 20+ Hand written GLSL nodes to speed up specific tasks better done on the GPU (10x speedup in most cases)~~

Migrated to Jovi_Capture

~~* STREAM READER node to capture monitor, webcam or url media~~ ~~* STREAM WRITER node to export media to a HTTP/HTTPS server for OBS or other 3rd party streaming software~~

Migrated to Jovi_Spout

~~* SPOUT streaming support WINDOWS ONLY~~

Migrated to Jovi_MIDI

~~* MIDI READER Captures MIDI messages from an external MIDI device or controller~~ ~~* MIDI MESSAGE Processes MIDI messages received from an external MIDI controller or device~~ ~~* MIDI FILTER (advanced filter) to select messages from MIDI streams and devices~~ ~~* MIDI FILTER EZ simpler interface to filter single messages from MIDI streams and devices~~

Migrated to Node Help

~~* Help System for ALL NODES that will auto-parse unknown knows for their type data and descriptions~~

Migrated to Node Colorization

~~* Colorization for ALL NODES using their own node settings, their node group or via regex pattern matching~~

UPDATES

<h2>DO NOT UPDATE JOVIMETRIX PAST VERSION 1.7.48 IF YOU DONT WANT TO LOSE A BUNCH OF NODES</h2>

Nodes that have been removed are in various other packages now. You can install those specific packages to get the functionality back, but I have no way to migrate the actual connections -- you will need to do that manually. **

Nodes that have been migrated:

• ALL MIDI NODES:
• • MIDIMessageNode
• • MIDIReaderNode
• • MIDIFilterNode
• • MIDIFilterEZNode

Migrated to Jovi_MIDI

• ALL STREAMING NODES:
• • StreamReaderNode
• • StreamWriterNode

Migrated to Jovi_Capture

• • SpoutWriterNode

Migrated to Jovi_Spout

• ALL GLSL NODES:
• • GLSL
• • GLSL BLEND LINEAR
• • GLSL COLOR CONVERSION
• • GLSL COLOR PALETTE
• • GLSL CONICAL GRADIENT
• • GLSL DIRECTIONAL WARP
• • GLSL FILTER RANGE
• • GLSL GRAYSCALE
• • GLSL HSV ADJUST
• • GLSL INVERT
• • GLSL NORMAL
• • GLSL NORMAL BLEND
• • GLSL POSTERIZE
• • GLSL TRANSFORM

Migrated to Jovi_GLSL

2025/04/14 @2.0.2:

• migrated out old routes to cozy_comfyui

2025/04/14 @2.0.1:

• numpy version set for < 2.0.0
• core supports switched to cozy_comfyui

2025/04/12 @2.0.0:

• REMOVED ALL STREAMING, MIDI and GLSL nodes for new packages, HELP System and Node Colorization system:

  Jovi_Capture - Web camera, Monitor Capture, Window Capture

  Jovi_MIDI - MIDI capture and MIDI message parsing

  Jovi_GLSL - GLSL Shaders

  Jovi_Spout - SPOUT Streaming support

  Jovi_Colorizer - Node Colorization

  Jovi_Help - Node Help

• all nodes will accept LIST or BATCH and process as if all elements are in a list.

• patched constant node to work with MATTE_RESIZE

• patched import loader to work with old/new comfyui

• missing array web node partial

• removed array and no one even noticed.

• all inputs should be treated as a list even single elements []

2025/03/28 @1.7.46:

• ~~updated requirements for numpy to only be >=1.26.4~~
• removed to keep numba working with numpy < 2.0

2025/03/25 @1.7.45:

• no work around comfyui not doing type conversion past version 1.10.14

2025/03/18 @1.7.42:

• updated numby jit to ignore python objects
• aligned float("NaN") constructs

2025/03/18 @1.7.40:

• allow vectors to be inline inputs + widget cause waiting for ComfyUI team is painful
• changed precision default to 3
• merged new action trigger from ComfyUI team

2025/03/06 @1.7.34:

• prep for Purz stream
• removed security scanner failures for in-line http links
• auto-size masks during mask add
• fix some limits on transform node
• better constraints for UNARY and BINARY OP nodes
• fix inversion in pixel merge
• defaults for regex colorizer entries

INSTALLATION

Please see the wiki for advanced use of the environment variables used during startup

COMFYUI MANAGER

If you have ComfyUI Manager installed, simply search for Jovimetrix and install from the manager's database.

MANUAL INSTALL

Clone the repository into your ComfyUI custom_nodes directory. You can clone the repository with the command:

git clone https://github.com/Amorano/Jovimetrix.git

You can then install the requirements by using the command:

.\python_embed\python.exe -s -m pip install -r requirements.txt

If you are using a <code>virtual environment</code> (<code><i>venv</i></code>), make sure it is activated before installation. Then install the requirements with the command:

pip install -r requirements.txt
