JPEG to BMP conversion in C for PIC32

Question

I am working on a project that required to read JPEG image in the SD card and display it to the LCD (using 32 bit PIC microcontroller). I am able to read the BMP image based on the Byte[] and plot to LCD pixel by pixel. However, how can we decode the JPEG image to pixel based on its Byte[]?
Thanks.

Probably worth starting here: Microchip Forums>JPEG Decoding

I read through the information there. Unfortunately, my code still not working well.

Use libjpeg.

http://libjpeg.sourceforge.net/[^]

It will likely take some effort to compile for the PIC.

I found another similar lib (picojpeg) which is quite similar to libjpeg.
However, there are example of the source code that adopted picojpeg to PIC32 environment.

After perform some modification, It is working...
Thanks for the suggestion.
