Image Layered TIFF / PSD Converter

Problem to solve

When design, print, or image-analysis workflows require a raster image to be split into independently inspectable channels, a normal export often produces only one flattened file: RGB values are mixed, CMYK separation is hard to audit, Alpha channels cannot be delivered alone, and hard shapes such as logos or text must still be extracted from the source. image-layered-tiff addresses this by converting JPG, PNG, BMP, and WebP files into multi-page TIFF or Photoshop PSD output, with each channel or detection result stored as a separate layer.

How it works

It provides several layer modes: rgb, rgba, cmyk, alpha, gray+color, hsl, lab, and edge-extract. The default output is multi-page TIFF, where each page represents one layer; with --format psd, channels are visible directly in the Photoshop Layers panel. CMYK conversion prefers system ICC profiles, and compression can be set to none, LZW, Deflate, or JPEG, defaulting to LZW. The edge-extract mode produces grayscale layers such as Canny-Edge, Gradient-Mag, and Binary-Edge, which are useful for extracting logos, text, lines, and other hard edges; --edge-threshold controls sensitivity.

Limits and cautions

This skill is useful for print separation, channel analysis, Alpha export, grayscale comparison, and contour extraction, but it does not redraw images or generate vector paths. TIFF may need to be inspected via layers or video-frame import in Photoshop, while PSD is more directly inspectable but may be larger. If the source image is low-resolution or blurry, edge-extract quality is limited by the input; cross-color-space CMYK results also depend on the ICC profile.
