Images

resize: Resizes to width and/or height (or a spec string in Go’s syntax, e.g. "600x400 webp q75").
fill: Crops and resizes to fill width×height at anchor.
fit: Downscales to fit width×height.
crop: Crops to width×height at anchor.
process: Any of the above per spec (or the typed kwargs).
image_filter: Applies filters, a list of {"op": …} maps, one per Go images.* filter: brightness, color_balance, colorize, contrast, gamma, gaussian_blur, grayscale, hue, invert, saturation, sepia, sigmoid, unsharp_mask, pixelate, opacity, padding, overlay and mask (image: a resource), auto_orient, text (text, color, size, x, y, alignx, aligny, linespacing, font: a font resource), dither (colors, method, serpentine, strength), process (spec). E.g. img | image_filter(filters=[{"op": "text", "text": page.title, "size": 40}, {"op": "dither"}]).
exif: EXIF data of an image, or none.
image_colors: Not implemented yet: calling it is an error (Go’s .Colors gives the dominant colours as hex strings).
qr_code: A PNG image resource of the QR code of text, with Go’s bytes and name (<target_dir>/qr_<hash>.png): level low, medium (default), quartile or high; scale pixels per module (at least 2, default 4). E.g. qr_code(text=page.permalink, target_dir="images/qr").
