<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I noticed that when my program is reading bands of
an image - the first calling RasterIO function is slow, and next RasterIO calls
(for second and third band) are very fast, almost immediate.</FONT></DIV>
<DIV><FONT face=Arial size=2>I checked if it was the fault of the first band,
but no matter which band you read, every time olny the first calling of RasterIO
function is slow...</FONT></DIV>
<DIV><FONT face=Arial size=2>I had this delay on every image drawing,so, since i
was opening and closing a GDALDataset every time, i though,
maybe the first time of reading a Dataset is slow, because it has to init
something - so i put Dataset as static var, and i don't create a new one every
time - but as before, the first calling to RasterIO function at every image
drawing is slow...</FONT></DIV>
<DIV><FONT face=Arial size=2>Do you have any ideas why it happens?</FONT></DIV>
