ImageDrawPiesliceByContainer

ImageDrawPiesliceByContainer is the ImageDrawPieslice you don't have to size yourself: hand it an image and it draws the filled wedge at that image's exact dimensions. Same bounding box, same start/end angles, same outline and fill controls, same anti-aliasing - the canvas size just comes from a container instead of width/height boxes.

How it works

It reads the width and height of the first frame of the container input and forwards them into ImageDrawPieslice, which does the drawing: RGBA canvas, PIL ImageDraw.pieslice inside a normalized bounding box, supersample by SSAA, downscale with method. As with all ByContainer draw nodes, the container sets the size only - the wedge is drawn on a fresh transparent canvas and the container's pixels don't appear in the output. Composite the two if you want the slice over the container's content.

Inputs that matter:

• container - any IMAGE; its size becomes the canvas.
• start_x / start_y, end_x / end_y - the wedge's bounding box as 0–1 fractions; defaults 0,0 → 1,1 span the whole canvas.
• start / end - angle range in degrees (0–360), PIL-style (3 o'clock, clockwise). Default 0 → 240 is a three-quarter wedge; set end to 360 for a full disc.
• outline_size - outline stroke width, default 1.
• outline_red / green / blue / alpha - outline color, default black.
• fill_red / green / blue / alpha - fill color, default white.
• SSAA (default 4) and method (default lanczos).

Why you'd use it

The container-tracking pattern: one container drives the size of both your drawn slices and your compositing, so a progress-ring or chart segment always matches the image it sits under without you rechecking dimensions. Swap the container, everything scales together.

The gotcha

Output is RGBA with a transparent background - the wedge floats on a checkerboard in Preview, which is ideal for compositing but surprising if you expected a backdrop. And the default wedge is 240°; remember to push end to 360 for a complete disc.

Installing Allor

Part of the Allor Plugin (Nourepide/ComfyUI-Allor), ~90 nodes from early 2024:

cd ComfyUI/custom_nodes
git clone https://github.com/Nourepide/ComfyUI-Allor
cd ComfyUI-Allor
pip install -r requirements.txt

Restart, or search "Allor Plugin" in ComfyUI Manager - the more reliable route given the pack's history of manual-install import errors (reinstall via Manager was the repeated community fix). Dependencies are rembg + onnx; drawing needs no models.

Gotchas that apply to the whole pack

The repo was rebased to strip images from history (shrank ~344×), so git pull/auto-update can occasionally break - the README's update-troubleshooting docs cover it; delete-and-reclone is the blunt fix. [Allor] console lines at startup are the pack writing config.json and checking updates, not an error.
