Dwg to JPG, at 300dpi?

Hi

I am using LDT2004 and can't figure out how to "print" or export a layout to a high resolution jpeg. JPGOUT and Plot\PublishToWeb JPG create a 96dpi image. In the Plot\Properties dialogue box there is a slider for resolution but it cannot be moved off 100dpi.

Help!

What is your final destination with the JPG file? Ultimate use?

JPEG as output from AutoCAD is meant to be a one use single snapshot kind of
output: making AutoCAD output higher DPI will not only take a while, but
create a huge file.

Try plotting to EPS from AutoCAD, then pulling that file into a graphics
program like Photoshop and output to desired JPG setting.

I have had good success with printing the file and using a scanner to
scan at desired resolution and color depth. Scanners software usually
has anti-aliasing features as well for even higher quality at lower
resolutions. Primitive, but effective, easy and predictable.

If you have the full blown Acrobat6 you can export to .jpg from a .pdf
file that you could create from autocad, there are some options (quality
and smoothing/anti-aliasing) but I cannot find the resolution settings.
I was getting 200 dpi .jpgs with the default settings.

Thanks for your reply. We are short staffed and I need to give a jpg to a colleague so that they can draw some graphics on top of the image (presumably with Paint or something similiar). The AutoCAD drawing contains several 160+ meg air photos so I am sure any jpg snapshot will be significantly smaller (like <10 megs). Within AutoCAD's print dialogue there is a slider for dpi but you can't move it off 100dpi. It would appear this aspect of AutoCAD hasn't improved over R14. It was a total bear in R14 and we gave up and used the "print and scan" method. However this degrades our air photos far too much. Why can't I move that dpi slider to 150, 200, 300?

Thanks

John

From your description you need details and JPEG is not it.

Explore SAVEIMG command, it uses your screen resolution for the output file.
It also uses better formats than JPG.

Also explore plotting to EPS, then processing the file in a Graphics program
that can read EPS: plenty of low cost and freebies out there if you don't
already have a product in house.

AutoCAD is not a graphics program, it's CAD: raster plotting is not it's
feature just an ability. Setting AutoCAD's DPI higher will result in 40-50MG
Jpg files, not the <10mg you seek.
