Unknown option name '-a_ullr' #53

When converting a png file without srs to a tif file with srs, we can use the command: gdal_translate in.png out.tif -a_srs EPSG:4326 -a_ullr ulx uly lrx lry ERROR 6: Unknown option name '-a_ullr' was thrown from gdal3.js

Or any way to set coordinateTransform of a dataset?

I had the same issue and figured this out after much trial and error. The syntax for -a_ullr is like this: [ '-of', 'PDF', '-a_srs', 'EPSG:4326', '-a_ullr', ulx.toString(), uly.toString(), lrx.toString(), lry.toString()]

@you-knowww, thanks for the solution.
