#define IMG_SUPPORT_IMAGE_DECODER_LOOP_CALLBACK
Overview
The decoder may takes up significant amount of time decoding an image and user may want to update some information on the display or to send/receive data through some communication channels. It is possible to release processing power in the middle of decoding process by calling a callback function provided by the user. The user should do all the housekeeping activities inside the function. This option can be enabled by adding this macro in ImageDecoderConfig.h.
