I am doing control c on the turbo cad image then copying it in microsoft digital image pro and saving as a jpeg. I find that when I save it as jpeg in turbo cad the time it takes is very long and often freezes the program.
If I may make a suggestion, try 'Save as' a .BMP with a setting similar to the attached or higher if your machine will handle it. The saved file around 10MB. I then open the file in a free program called Irfanview and save as a .jpg.
The size of the file is greatly reduced 300 - 400kb. approx. and there's no jaggies.
