ERROR large raster files (.ecw) maybe solved

Feb 14, 2012 at 12:46 PM

I'm new in programming dotspatial.
is really an interesting project.
I tried to load an ecw very heavy. Resulting memory error. But then I tried to change the code "GdalImageSource.cs".
the error comes from the second step of "byte [] vals = new byte [width * height * 4];"
I set the condition
if (vals == null) {
vals = new byte [a + 1];
}.
The game is done.
is that correct?

Note that images and rasters are currently different objects in DotSpatial.

In both cases the code tries to create arbitrarily large arrays, which doesn't work for large files.

I see the statement you referenced copied to 13 different places, so I expect there is some room for improvement, but I think there will be more work needed...

How does the correct byte array return after your changes?
