	// MaxPosterHeight is the maximum height for poster images (optimized for Jellyfin/Plex/Emby)
	// Reduced from 1000px to 500px for better file sizes and performance
	MaxPosterHeight = 500

	// LandscapeAspectRatioThreshold determines if an image is landscape-oriented
	// Images with width/height > this value are considered landscape (typical JAV covers are ~1.5)

Functions ¶

func CropPosterFromCover ¶

func CropPosterFromCover(fs afero.Fs, coverPath, posterPath string) error

CropPosterFromCover intelligently crops a cover image to create a poster

Strategy: - Landscape images (aspect ratio > 1.2): Crop right 47.2% (original Javinizer behavior) - Square/Portrait images (aspect ratio <= 1.2): Center crop to 2:3 aspect ratio - If result exceeds MaxPosterHeight, resize maintaining aspect ratio

This ensures good results for both wide JAV covers and square promotional images

func CropPosterWithBounds ¶

func CropPosterWithBounds(fs afero.Fs, coverPath, posterPath string, left, top, right, bottom int) error

CropPosterWithBounds crops a cover image using explicit pixel bounds. Bounds are in source-image pixels and must be within the image dimensions.
