RETURN TYPEboolean

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Encodes array of images into a memory buffer.

The function is analog to cv::imencode for in-memory multi-page image compression. See cv::imwrite for the list of supported formats and flags description.

imencodemulti(ext: EmbindString, imgs: MatVector, buf: ucharVector, params: IntVector): boolean;

2 available overloads

imencodemulti(ext: EmbindString, imgs: MatVector, buf: ucharVector): boolean;

ext

File extension that defines the output format. Must include a leading period.

imgs

Vector of images to be written.

buf

Output destination, filled by the native operation. Output buffer resized to fit the compressed data.
