This preprocessor is mainly targeted to a problem of tile that sometimes it causes color offsets.

Comparison 1 (advantages)

meta (in txt2img, similar to img2img with denoising strength 1.0)

1girl, best quality
Negative prompt: lowres, bad anatomy, bad hands, cropped, worst quality
Steps: 20, Sampler: Euler a, CFG scale: 7, Seed: 12345, Size: 512x640, Model hash: 8712e20a5d, Model: Anything-V3.0, Clip skip: 2, Version: v1.2.1, ControlNet 0: "preprocessor: tile_XXXX, model: control_v11f1e_sd15_tile [a371b31b], weight: 1, starting/ending: (0, 1), resize mode: Crop and Resize, pixel perfect: True, control mode: Balanced, preprocessor params: (64, 1, 64)"

zoom in view (for visualization, not used)

tile_resample: (has color offset problem)

tile_colorfix (all parameters same with tile_resample): (color offset problem fixed)

Comparison 2 (limitation)

Note that tile_colorfix always lock colors, which means you cannot edit color even in "My prompt is more important" mode

1girl, best quality, in blue dress
Negative prompt: lowres, bad anatomy, bad hands, cropped, worst quality
Steps: 20, Sampler: Euler a, CFG scale: 7, Seed: 12345, Size: 512x640, Model hash: 8712e20a5d, Model: Anything-V3.0, Clip skip: 2, Version: v1.2.1, ControlNet 0: "preprocessor: tile_XXXX, model: control_v11f1e_sd15_tile [a371b31b], weight: 1, starting/ending: (0, 1), resize mode: Crop and Resize, pixel perfect: True, control mode: My prompt is more important, preprocessor params: (64, 1, 64)"

Note that we have "in blue dress" in the prompt.

tile_resample: (dress color changed)

tile_colorfix (all parameters same with tile_resample): (failed/collapsed)

Version

You need at least 1.1.195 to use it.

Also, since we have quick control type filter in UI now, we do not need to worry about the list becomes longer and longer:
