PD Image Crop Location_V2

PDImageCropLocation_V2 is the edge-trimming cousin of the pack's coordinate crop, and it does two things the V1 doesn't: it crops from an edge rather than from arbitrary coordinates, and it hands back a mask that's guaranteed to line up - even manufacturing an all-white one when you don't provide any.

The workflow that makes this shine: "cut N pixels off the left side of every frame, and keep the mask in sync so my inpaint or composite doesn't drift." The author clearly built it for mask-bearing pipelines, and the mask handling is where the design decisions live.

How it works

x is the number of pixels removed, not kept - the most important thing to internalize. crop_direction says which edge gets shaved:

• left → keeps image[:, :, x:] (drops the left x pixels)
• right → keeps image[:, :, :width-x]
• top → keeps image[:, x:, :, :]
• bottom → keeps image[:, :height-x, :, :]

No cropping happens to the other dimensions - it's a straight strip removal, so nothing gets resized or re-sampled. If x is bigger than the relevant dimension, it raises a ValueError rather than returning a degenerate crop.

The mask side is the interesting bit. If you connect a MASK, it gets the identical slice. If you don't, the node creates an all-white mask sized to the output. That second behavior is why you can wire the outputs straight into an inpaint or a ComfyUI-Inpaint-style node without ever thinking about mask alignment - the mask is always valid and always registered.

The inputs that matter

• image (IMAGE) - source.
• x (INT, default 50) - pixels removed from the chosen edge. Default 50 means 50 pixels gone the moment you drop the node in.
• crop_direction - left/right/top/bottom (default left).
• mask (MASK, optional) - cropped alongside; absent → all-white mask generated.

Outputs: cropped_image (IMAGE) and cropped_mask (MASK).

Real uses

Border removal is the classic: scans and screenshots with uneven edges get a fixed strip taken off cleanly, in a batch, deterministically. Watermark or black-bar trimming off one edge is a one-node job. And in a masking pipeline, the free all-white mask is genuinely handy - you can chain the output into a mask-based blend without a separate "create solid mask" node.

Gotchas

Remember x = amount removed. The default of 50 will visibly shave your image the first run, which is fine once you know it - but it's easy to misread as "keep 50px." Also, unlike the pack's ratio/custom crops, this one has no axis choice: horizontal directions (left/right) always apply to width, vertical to height. And the generated mask when none is supplied is all-white, which in a mask-is-foreground convention means "everything kept" - if your downstream treats white as cut, flip it.

Install

ComfyUI Manager: search PDuse (repo 7BEII/Comfyui_PDuse), install, restart. Or:

cd ComfyUI/custom_nodes
git clone https://github.com/7BEII/Comfyui_PDuse
cd Comfyui_PDuse
pip install -r requirements.txt

Restart and it shows as PD Image Crop Location_V2 under PDuse/Image. Edge trims plus free masks - the most useful crop variant in this pack for compositing work.
