So I got GDAL binding work. And now I need to understand how to
translate C code to D.
Here is simple tutorial: http://www.gdal.org/gdal_tutorial.html If I
right understand it's easier to take C, than C++ code example.
Now I am trying to get very simple example work. My code is:
string fileTiff =
`D:\code\RSM2DOC\data-example\03022014_101_022731_09_10_Rostov.tif`;
if (!fileTiff.exists)
writeln("Tiff file do not exists");
GDALDatasetH hDataset = GDALOpen( toStringz(fileTiff),
GDALAccess.GA_ReadOnly );
GDALDriverH hDriver;
hDriver = GDALGetDatasetDriver(hDataset);
double adfGeoTransform[6];
if( GDALGetGeoTransform( hDataset, adfGeoTransform ) == CE_None )
{
writeln(adfGeoTransform[1]);
}
function (void*, double*) is not callable using argument types (void*,
double[6])
I can't understand why this error is rise up. It's look like 1-to-1 with
C code.
Also I can't understand at what moment adfGeoTransform get in it value.
GDALGetGeoTransform is declared to take a pointer to a double (array of
doubles). While adfGeoTransform is declared as a static array [1] of
doubles. Static arrays are stack allocated and passed by value, the
function expects an array which is passed by reference. Try adding
".ptr" to "adfGeoTransform" in the call to GDALGetGeoTransform.
