Mac OS How to create an image from PNG data?

Question

I have a data array representing 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,
...

}

Can I create a PNG file using this data? If yes, then HOW?

Answer 1

Create a data provider to serve the data, and then create an image with the data provider .

Answer 2

Create a graphic context for the image and draw it. then save to png

Create CGBitmapContext

draw pixels

create CGImage creation from CGBitmapContext

save CGImage as PNG using CGImageDestination

Answer 3

really close, just use the stream to save your array as "picture.png". If your hex is correct and you have an 8-byte signature before the pixels, it should work.
