FaceCompressor.compressWebpFromCroppedPortrait Method¶

Definition¶

Compresses a pre-cropped portrait image to WebP so that its size does not exceed the given byte budget.

The WebP quality is searched automatically to find the highest quality whose encoded size fits within byte_budget. If even the lowest quality does not fit, the function fails and no data is returned.

Important

The input image must be in 24-bit BGR format. No compression model needs to be loaded since the standard WebP codec is used directly.
