Hi,there:
Thanks for the comments !
I think I need to specify more detail about my mission.
I just worked on file which contain the image info, I need to get the
info from the huge file. The file format like:
Structure Table 1;
Structure Table 2;
pixel 1:
{
Loop 1:
data Structure 1
data Structure 2
...
until data struture.member1 == 0;
}
pixel 2:
{
Loop 1:
data Structure 1
data Structure 2
...
until data struture.member1 == 0;
}
...
What I need is to get the info for the pixel to draw the image.
Although the pixel is huge, but within each pixel, I need to add the
data structure member2 to get the value of pixel.
At first, I just read the pixel by pixel, that is a very small file
which just contain 11M. For this method, it seems worked very slow.
Then I used one byte array allocate the size of the file. Then used
the byte array to convert it to int using shift.
It improved the performance a lot.
But the real data file I will deal with is more than 11M. It is more
than 500M.
That is my problem.
So anyone have such idea ?
Best Regard
Quanyu Zhu
