Hi...

I have a geo tiff file which containing the 14000 X 14000 Pixels
(Samples and Lines), I am reading it through the read_tiff function.
Over here i want to show that image on to the 500 X 500 window Means
by buffer for image will contain dimension [3,500,500]. For that I am
reading with the help of read_tiff function with the sub_rect keyword.
Where i m reading the pixels based on the ratio of 14000/500, but it is
taking to much time. While the same thing in ENVI it is taking less
time to read the image and display it. So is there any other method for
read that image fast. for that i have to write my own code in IDL to
read the tiff file?

Regards,
Chintan Raval
