Ramesh,<br><br>Instead of 'pasting' a part of your code, could you attach your entire .cpp file along with the main() function and stuff?<br><br><div class="gmail_quote">On Tue, Feb 22, 2011 at 9:49 AM, user gdal <span dir="ltr"><<a href="mailto:userofgdal@gmail.com">userofgdal@gmail.com</a>></span> wrote:<br>

Thanks a lot for reply about zero pixel values when I attempted to<br>
write into an output image file. Though I pasted the code I wrote for<br>
programmatically 'copying' the image, once again I am pasting the same<br>
below.<br>
<br>
Q. "One thing I notice about your code is that you only appear to read<br>
and write the first scanline of the image. Is this intentional?"<br>
<br>
Ans. No. I want to copy the whole image. Please see the function<br>
ReadNWrite(...). Am I reading only the first scanline? Oh my God! In<br>
the syntax of the function RasterIO of GDALDataset, it seems there is<br>
no parameter with scanline number. Can you please solve the problem<br>
for me. Before call of the function ReadNWrite, I wanted to 'prepare'<br>
the output image (see the function CreateOutputImg). The problem<br>
should be in the functions CreateOutputImg, ReadNWrite, Read and<br>
Write.<br>
<br>
Another worry is projection information, which I wanted to put in<br>
CreateOutputImg. I am sure there are some serious shortcomings in my<br>
attempt. How to set that correctly?<br>
<br>
Q. "For the purposes of asking a question of the list it would be helpful if<br>
you could boil your program down to a minimum example including all the<br>
essentials. It will require extra work on your part, but will make it<br>
much easier for the many members of the list who might want to skim<br>
through the code to see if they have suggestions".<br>
<br>
Ans. I have made some more effort to make my difficulty more specific.<br>
Now I request all of you to kindly solve it and if possible, post in<br>
the website.<br>
<br>
Thanks once again.<br>
<br>
Yours sincerely,<br>
Ramesh<br>

The class's destructor closes the output dataset ("outds") using GDALClose.<br>
