ComfyUI-Jax-Nodes

Custom ComfyUI nodes for some niche Krita-focused workflows and easier prompt / pipeline handling.

Nodes Overview

• Conditional Select (JAX_ConditionalSelect)

  • Simple if/else node: chooses between true_value and false_value based on a boolean condition and outputs the selected value.

• Sampler Pipe In (JAX_KritaPipeIn)

  • Packs a set of sampler-related inputs (model, positive, negative, vae, image, clip, latent) into a single pipe dictionary that can be passed around a workflow.

• Sampler Pipe Out (JAX_SamplerPipeOut)

  • Unpacks the pipe dictionary back into individual outputs (model, positive, negative, vae, image, clip, latent), useful for branching or recombining pipelines.

• Krita Strength (JAX_KritaStrength)

  • Given sigmas, a strength, and a denoise value, computes an integer step index that approximates Krita-style strength control for diffusion, clamping values to safe ranges.

• Krita Resize Canvas (JAX_KritaResizeCanvas)

  • Output node that, when enabled, emits a small JSON payload in the UI (application/x-krita-command) describing a resize_canvas command with the chosen width and height.

• Image Size Multiplier (JAX_ImageSizeMultiplier)

  • Multiplies an input width and height by a multiplier and outputs the new dimensions plus a small Markdown string summarizing the final size.

• Easy Prompt (W/ Append) (JAX_EasyPrompt)

  • CLIP text encoder that lets you write prompts with inline LoRA tags like <lora:name:weight> and append extra positive/negative text. It loads and applies LoRAs to the model/clip, then returns the updated model and positive/negative conditioning.

• Easy Prompt (JAX_EasyPromptSimple)

  • Simpler version of the above: supports <lora:...> tags but without extra append fields, just positive and negative inputs.
