Icy ImageScale

IcyImageScale is the ComfyUI-IcyHider wrapper of core ImageScale - same node, renamed class so the privacy extension can hide it. And a quick reality check before the details: this is a geometric resize, not a super-resolution upscaler. The KB's upscaling doc splits "make it bigger" into three very different jobs, and this node only does the first one - more pixels, no invented detail. If you want a model to hallucinate plausible new detail (faces, textures), you want an ESRGAN-family upscaler or a tile-ControlNet pass, not this. But for getting an image to a specific resolution, this is the node.

Inputs that matter

• image (IMAGE) - whatever you're resizing.
• upscale_method (enum) - nearest-exact, bilinear, area, bicubic, lanczos. For most work bicubic or lanczos (sharper, slightly slower) is right; nearest-exact gives you chunky pixelated scaling (useful for testing and for step-edges like pixel art); area is good for downscaling without shimmer. Don't overthink it - bicubic is the safe default.
• width / height (INT, 0–16384, default 512) - the exact output dimensions.
• crop (enum, disabled / center) - what to do when your source's aspect ratio doesn't match the target. disabled squishes/stretches the image to fit exactly; center scales to cover the target and crops the middle. If you're resizing into a fixed-size latent canvas (multiples of 8, remember), center crop is usually what you want to avoid distortion.

Output: a single IMAGE at the requested size.

Where it fits in a workflow

• Prepping condition images for ControlNet. ControlNets want their condition map at the model's generation resolution - resize your edge map or pose render to match the latent canvas.
• Standardizing inputs. ImageBatch needs matching dimensions; a quick ImageScale on both sources makes them fit.
• img2img / hires prep. Feed a scaled image into a sampler's latent path (via VAE encode) to control the exact working resolution.

Installing it

cd ComfyUI/custom_nodes
git clone https://github.com/icekiub-ai/ComfyUI-IcyHider

Restart, or use ComfyUI Manager (search "IcyHider"). No pip dependencies, no models.

Common issues

• Missing node in shared workflows - install the pack or swap in core ImageScale.
• "It stretched my image." You left crop on disabled with a mismatched aspect ratio. Switch to center.
• "The upscale is soft." Again: this is a resize, not a detail-generator. For real quality upscaling, reach for the actual upscaler nodes - the KB's hierarchy puts pixel upscalers (Lanczos, ESRGAN models) and generative restorers (SUPIR, SeedVR2) in separate jobs, and this node is firmly in the "more pixels" bucket.
