I can read a raw of 640x480 bytes with:
raw_file=open('sent_internal.raw')
raw_file=open('sent_internal.raw','rb')
raw_image=raw_file.read()
It likely contains a lot of 0 values, black=0. The result above is a
string of 242 characters. I'm guessing the 0's were ignored, and only >0
values were kept. If so, how do I get all 307200 bytes into a read?
Whoops ... Ah, I missed 'rb'; however, I want to continue.
ah
I found the minimum value among the first 242 items to be 31 without the
'rb'.
the first 32 characters in ascii are control characters
Among the 307200, I found it to be 150, which I believe is
correct. That is, there are pixels in the image that are pretty bright.
So what weirdness took place w/o the 'rb'? Why no 150?
not sure what this means...
One more question, when I tried (no 'wb')
assuming you mean 'rb' above
read(size=307200),
why di read
balk at size, syntactically.
read terminates upon first end on line character encountered
HTH,
