Hello,

 

I would like to do a jp2000 file with a tif.

 

My conditions :

 

1- the tif is black on white so i want my jp2 black on white

 

2- the siz of the jp2 must be less than the tif

 

 

Using rasterpalletremover my jp2 is 500Ko big but i need to specify nodata=0 in Qgis to see it in black on white instead of white on black..

 

See joined files (fil and jp2 500 Ko).

 

I test many ways like rasterpaletteresolver and the viewing is ok but the files is three times bigger!!!(2.9Mo).

 

 

If anyone can help me

 

 

thanks,
