Optimize Images 4k

ImageMagick으로 image 모음을 정리·최적화해 4K landscape 출력 생성. Use when 세로 이미지 삭제, 최소 너비 미만 이미지 삭제, wider JPEG를 3840px로 resize(aspect ratio 유지), 해상도 suffix rename(-6000px.jpg→-3840px.jpg), cover 파일 제거, 또는 image 모음 검증이 필요할 때.

Optimize Images 4K

Use scripts/Optimize-Images4K.ps1 instead of rebuilding fragile ImageMagick loops.

Workflow

Confirm ImageMagick is installed. The script discovers magick.exe from PATH and common Windows install locations.
Run a preview first:

& scripts/Optimize-Images4K.ps1 -Root <target>

Report preview counts. Obtain confirmation before destructive work unless the user already explicitly requested deletion or conversion.
Apply the requested cleanup and conversion:

& scripts/Optimize-Images4K.ps1 -Root <target> -Apply

Verify separately:

& scripts/Optimize-Images4K.ps1 -Root <target> -VerifyOnly

Defaults

Recurse through all subdirectories.
Process .jpg and .jpeg.
Delete images where height is greater than width.
Delete images where width is less than 3840.
Resize images wider than 3840 to exactly 3840px, preserving aspect ratio.
Optimize JPEGs with metadata stripping, 4:2:0 sampling, progressive encoding, and quality 90.
Rename a trailing resolution suffix such as -6000px.jpg to -3840px.jpg.
Delete *-board.jpg, *-poster.jpg, and warning-cover.png.
Leave images already exactly 3840px wide uncompressed.

Options

Use -Width <pixels> for a target other than 3840.
Use -Quality <1-100> to change JPEG quality.
Use -KeepPortrait, -KeepUndersized, or -KeepKnownCovers to disable deletions.
Use -NoRename to preserve filenames.

Safety Rules

Never add -- before Windows source paths in ImageMagick conversion commands; it can strip path separators in this environment.
Replace an original only after the temporary output exists and verifies at the target width.
Never overwrite a rename collision.
Treat FAILED=0, PORTRAIT_REMAINING=0, UNDER_WIDTH_REMAINING=0, and OVER_WIDTH_REMAINING=0 as required completion evidence.
