我有大量的UInt8数据，这是一张图片。 如何从中创建图像？

Sorry for the very open ended question, but I have a dumped file that looks like this:

 1 TypelessData image data (174776 items)
  0 int size = 174776
  [0]
   0 UInt8 data = 85
  [1]
   0 UInt8 data = 69
  [2]
   0 UInt8 data = 53
  [3]
   0 UInt8 data = 38
  [4]
   0 UInt8 data = 0
  [5]
   0 UInt8 data = 255
  [6]
   0 UInt8 data = 255
  [7]
   0 UInt8 data = 0
  [8]
   0 UInt8 data = 63
  [9]
   0 UInt8 data = 47
  [10]
   0 UInt8 data = 31
etc..

This should be a PNG image. Where do I start looking? Is there any way to create a PNG from this using PHP? (I can write some code that converts the data into a PHP array) but I have no idea what to look for here. Thanks!

Here are more data:

Width: 512
Height: 512
Size: 174776
