Bjørn Erik Pedersen	e569dd59a0	Misc webp performance work ... *- Dynamic pool sizing for WebP and Katex based on CPU count - WebP decode: use RGB (3 bytes) for opaque images instead of RGBA (4 bytes) - Add new imaging.config with new encoder method option; this is default 4 (what we had before), if have tested with value 2 for a 30% speedup on my MacBook, but that does sacrifice quality in some cases (quality/speed trade-off 0-6) - Track hasAlpha in decode response to enable RGB optimization - Scale image processing workers (1->2) on high-core machines - Add WebP benchmark test On my MacBook Pro M1 Pro, I now get these numbers compared to Hugo v0.152.0: ``` goos: darwin goarch: arm64 pkg: github.com/gohugoio/hugo/internal/warpc cpu: Apple M1 Pro │ cmp152.bench │ fix-webpbench.bench │ │ sec/op │ sec/op vs base │ Webp-10 162.6m ± 32% 145.3m ± 21% -10.60% (p=0.026 n=6) │ cmp152.bench │ fix-webpbench.bench │ │ B/op │ B/op vs base │ Webp-10 41.69Mi ± 0% 123.79Mi ± 0% +196.92% (p=0.002 n=6) │ cmp152.bench │ fix-webpbench.bench │ │ allocs/op │ allocs/op vs base │ Webp-10 9.963k ± 3% 18.797k ± 2% +88.67% (p=0.002 n=6) ``` For general image resize benchmarks compared to Hugo v0.152.0 (note that that's not the result of this branch): ```bash goos: darwin goarch: arm64 pkg: github.com/gohugoio/hugo/resources/images cpu: Apple M1 Pro │ cmp152.bench │ fix-webpbench.bench │ │ sec/op │ sec/op vs base │ ImageResize-10 84.12m ± ∞ ¹ 40.70m ± ∞ ¹ -51.61% (p=0.029 n=4) ¹ need >= 6 samples for confidence interval at level 0.95 │ cmp152.bench │ fix-webpbench.bench │ │ B/op │ B/op vs base │ ImageResize-10 32.37Mi ± ∞ ¹ 29.25Mi ± ∞ ¹ -9.64% (p=0.029 n=4) ¹ need >= 6 samples for confidence interval at level 0.95 │ cmp152.bench │ fix-webpbench.bench │ │ allocs/op │ allocs/op vs base │ ImageResize-10 11.34k ± ∞ ¹ 12.03k ± ∞ ¹ +6.07% (p=0.029 n=4) ¹ need >= 6 samples for confidence interval at level 0.95 ``` Closes #14370	2026-01-21 10:44:22 +01:00

Bjørn Erik Pedersen	1a94731669	Move from github.com/disintegration/gift to github.com/gohugoio/gift ... With some performance improvements upstream, there's improvements in memory usage. Note that the benchmark below is full site builds with image processing: ``` goos: darwin goarch: arm64 pkg: github.com/gohugoio/hugo/resources/images cpu: Apple M1 Pro │ benchcmp.bench │ feat-forkgift-14397.bench │ │ sec/op │ sec/op vs base │ ImageResize-10 74.60m ± 4% 73.75m ± 4% ~ (p=0.093 n=6) │ benchcmp.bench │ feat-forkgift-14397.bench │ │ B/op │ B/op vs base │ ImageResize-10 32.38Mi ± 1% 29.31Mi ± 1% -9.49% (p=0.002 n=6) │ benchcmp.bench │ feat-forkgift-14397.bench │ │ allocs/op │ allocs/op vs base │ ImageResize-10 12.53k ± 1% 12.05k ± 1% -3.82% (p=0.002 n=6) ``` Closes #14397	2026-01-19 22:18:45 +01:00
Bjørn Erik Pedersen	3ba147e702	images: Add images.Overlay filter ... This allows for constructs ala: ``` {{ $overlay := $img.Filter (images.Overlay $logo 50 50 )}} ``` Or: ``` {{ $logoFilter := (images.Overlay $logo 50 50 ) }} {{ $overlay := $img | images.Filter $logoFilter }} ``` Which will overlay the logo in the top left corner (x=50, y=50) of `$img`.
