Exact pixels: align canvas size with device density first
`resize-image-pixels` lines up comps or legacy fixed boxes: spell out fit-versus-crop before arguing about quality. Upscaling invents detail; downscaling may need gentle sharpening, not halos. Web teams must multiply logical CSS widths by DPR—shipping only 1x masters looks soft on Retina.
Recommended steps for pixel-accurate resizing
- Inside `resize-image-pixels`, capture target W×H, whether stretching is forbidden, and whether long or short edge leads.
- Review type and hairline UI at 100% and at the real DPR you ship to production.
- Embed `WxH` in filenames or folders and keep masters separate for `srcset` mapping.
Pixel resize Q&A
Design says 750px but engineering wants 2x assets—which do you export first?
Derive physical pixels from logical width × DPR before export—stop upscaling lazily and letting CSS shrink everything.
Copy looks soft after downscale—dimension issue or sharpening?
Confirm exported pixels still exceed display×scale; then check for over-sharpening or half-pixel shifts.
Batch PNG and JPEG to identical dimensions—any QA differences?
PNG needs alpha-edge checks; JPEG should stay sRGB and avoid another lossy hop in the pipeline.
Before publishing `resize-image-pixels` assets externally, which compliance checks are mandatory beyond visual quality?
Start with "enforce pre-release QA gates", "define size thresholds explicitly", and "track export parameters", then explicitly verify "batch naming collisions" and "alpha transition artifacts" before release approval.
Under deadline pressure, how should teams balance speed and stability in `resize-image-pixels` processing?
Start with "track export parameters", "run channel dry-runs", and "enforce pre-release QA gates", then explicitly verify "edge softness around text" and "color profile mismatch" before release approval.
