No response when using GDAL layer(imagery and elevation)

[wwwronin]

I try the rocky-demo, and there is no response when using GDAL layers . Here is screenshot.

Hello, can you provide more detailed information please?

[wwwronin]

I use vcpkg as build solution, VS2022 x64 bit compiler, Windows 10 Professional ,64bit. Here is the code I used in demo .
int main(int argc, char** argv)
{
// instantiate the engine.
rocky::EngineVSG engine(argc, argv);

// add an imagery layer
auto imagery = rocky::GDALImageLayer::create(); // rocky::TMSImageLayer::create();
imagery->setURI("./data/world.tif");
engine.map()->layers().add(imagery);

if (imagery->status().failed())
    return error(imagery->status());

// add an elevation layer
auto elevation = rocky::GDALElevationLayer::create();
elevation->setURI("./data/china_dem.tif");
engine.map()->layers().add(elevation);

if (elevation->status().failed())
    return error(elevation->status());

// run until the user quits.
return engine.run();

}

Is the problem the bump on the right in your screenshot? Can you provide your elevation tif, or post the output of gdalinfo china.tif?

Not only bump on the right ,the program seems no response(dead), I wait about 10 minutes, still no response.Here is the output of elevation file .

I assume it's fine with just imagery?
Can you attach your elevation geotiff?

[wwwronin]

I remove both elevation and imagery layer, the rocky-demo still no response when loading .

[wwwronin]

Try just only the imagery, still dead . I think there may have bugs in GDAL layer. Due to the size limitition, I cut a aera for you .

[gwaldron]

Thanks. Using your tif I was able to fix the elevation reader to make it work correctly.
However, I cannot reproduce the "lock up" problem you are seeing.

[wwwronin]

You are welcome. Lock up problem is caused of OS ,I switch the os to Windows 11 ,it idisappered.

[wwwronin]

I start another discussion you may see later. Multiple imagery layer there is a white aera .

[gwaldron]

Rocky doesn't support more than 1 imagery layer yet. It will in the future.
