I am having an issue when trying to generate slippy tiles, using gdal2tules which is great but take forever and may want a dry run for only one tile as a test, checking the output and so on, I dont like to generate a directory full of pictures/ tiles which takes about 3 days then discovering any issue, such as nodata filled as black.

I wired a gdal environment to use their api then discovered that gdal2tiles inst an API they got!!!!

My next try is to generate only requested tile from the tiff tile and generate a 256×256 tile as a server ‘and cache it’ as an approach, has anyone try to do this with gdal api? In c++ or best if there is a csharp version

I tried gdal tools downloaded along with qgis but not enough and slow
