High resolution raster plot problem

Сообщений 1 страница 2 из 2

Hi all,

I am working on plotting some FDO connected rasters of an area measuring ~ 40Km * 50km (See "image propreties"),
When I plot a small area , whatever the scale is , (1:1000, 1:2000 , ...1:50000) everything goes fine. The problem appears when I try to plot the whole raster on A0 paper size with a scale of 1:50000 , the result is a blurred image (see "sample1"), and this occurs whether using the printer (HP T790 Model) or  with DWG to PDF plotter or any other kind of plotter. I have adjusted every single parameter the plot window containes (See "plot") , I have increased all raster command parameters (rasterdpi, rasterthreshold, rasterpercent,... , I have raised memory in raster extension option , changed OLE plot quality ...., but in vain,

I get a bad image quality also when dealing with Ecw satellite images (1pixel= 0.25m) while trying to plot an area of 1Km² with a 1:1000 scale and A0 paper Format

Is there any solution for this problem

Thank You!!!

I didn't find the right solution from the Internet.
