Siemens C65 bmp to hex editor availability

Hello
I have just finished to start up a C65 display (SPI 10MHz) using PIC24H 
micro. After some pixel/fonts test I intend to pixelized a picture(bmp) 
but wit the tools that I tried the results were bad on scaling.
Somebody can help me with such a tool to transform a bmp to h file with 
16bit color ?

Thanks
