Converts the given Memory to a JPEG image and returns a pointer to the resulting image.

Mem must point to a data block of exactly (Width * Height) triplets of RGB image data bytes. Upon return, Size will hold the number of bytes of the resulting JPEG data. Quality can be in the range 0..100 and controls the quality of the resulting image, where 100 is "best". The caller takes ownership of the result and has to delete it once it is no longer needed. The result may be NULL in case of an error.

Converts the given array of UTF-8 symbols (including the terminating 0) into a sequence of character bytes of at most Size length.

Returns the number of character bytes written (without the terminating 0). If Max is given, only that many symbols will be converted. The resulting string is always zero-terminated if Size is big enough.
