Mac OS. How to create image from PNG data?

Question

Hi, all! I have an array of data that represents PNG:

unsigned short systemFontTexture[] = {

...
0x5089,0x474E,0x0A0D,0x5089,0x474E,0x0A0D,0x5089,
0x474E,0x0A0D,0x5089,0x474E,0x474E,0x0A0D,0x5089,
0x474E,0x0A0D,0x5089,0x474E,0x474E,0x0A0D,0x5089,
...

}
