Thumbnail Portrait — Upscale a 127-pixel thumbnail of an 1863 portrait 6x to 762 pixels wide. Face recovery rebuilds a sharp face where a plain upscale smears it. Photo: Alexander Gardner, via the Library of Congress (no known restrictions).

Parameters

image

stringrequiredSource image as a public HTTPS URL or a base64 data URI (JPEG, PNG, or TIFF)

output_width

integerminimum: 1maximum: 32000Desired output width in pixels. If only one dimension is set, the other scales proportionally. If neither is set, the source resolution is kept (enhancement without upscaling)

integerminimum: 1maximum: 32000Desired output height in pixels. If only one dimension is set, the other scales proportionally. If neither is set, the source resolution is kept (enhancement without upscaling)

output_format

stringrequireddefault: jpegenum: jpeg, png, tiffFormat of the upscaled image

crop_to_fill

booleanCrop to fill the requested dimensions instead of letterboxing when the aspect ratio differs

face_enhancement

booleanRun face recovery on detected faces

face_enhancement_strength

numberminimum: 0maximum: 1Strength of face recovery

face_enhancement_creativity

numberminimum: 0maximum: 1Face recovery style, from realistic (0) to creative (1)

subject_detection

stringenum: foreground, background, allWhere enhancements are applied

sharpen

numberminimum: 0maximum: 1Amount of additional sharpening

denoise

numberminimum: 0maximum: 1Amount of noise reduction

fix_compression
