LEADTOOLS provides the functionality to get and set JPEG compression for a TWAIN source. Use the L_TwainGetJPEGCompression function to obtain the current TWAIN JPEG compression settings by passing LTWAIN_GET_JPEG_COMPRESSION to the uFlag parameter. Similarly, obtain the default TWAIN JPEG compression settings by passing LTWAIN_GET_DEFAULT_JPEG_COMPRESSION to the uFlag parameter when calling the L_TwainGetJPEGCompression function.
To set JPEG compression for a TWAIN source, call the L_TwainSetJPEGCompression function, and pass LTWAIN_SET_JPEG_COMPRESSION to the uFlag parameter. To restore the default TWAIN JPEG compression, call the L_TwainSetJPEGCompression function and pass LTWAIN_RESET_JPEG_COMPRESSION to the uFlag parameter.
