Closed martinhschei closed 3 years ago

Is your feature request related to a problem? Please describe. Not a problem.

Describe the solution you'd like When i call parseGeoraster() i would like to be able to specify which "pyramid level" i want to be rendered initially.

Describe alternatives you've considered Nothing.

Additional context It might be possible already - but i have not been able to figure out if it is.

Hi, @martinhschei . I'm terribly sorry for the late reply. This is an excellent question. Are you passing in an array buffer or a url to a GeoTIFF. If you are passing in a URL to a GeoTIFF, you can call getValues with a width and height and it will automatically determine which pyramid/overview level to use based on the size. Technically, this is handled by the excellent geotiff.js library that georaster wraps around.

I'm currently working on a massive rework of GeoRaster, which I hope to publish within the next few months. I'll incorporate this feedback into this work, so you should be able to specify a specific pyramid/overview level then.

Thank you for your patience and let me know if you have any further questions.

Great! Looking forward to the new version then!
