Example

PNG_HEADER = [137, 80, 78, 71, 13, 10, 26, 10]

filePath = "/sys/pics/tank.png"
rawImg = file.loadRaw(filePath)

isPNG = true
for i in range (0, PNG_HEADER.len - 1)
	isPNG = isPNG and PNG_HEADER[i] == rawImg.byte(i)
end for

if isPNG then
	print filePath + " is a PNG file"
end if

This example loads a file as a RawData buffer, and then checks the first 8 bytes to determine if it is a PNG file.
