DWG to JPEG

360 Views, 4 Replies

Hello, I am looking into exporting to a JPEG. I have read the articles and have also tried the pdf creator. PDF creator works well but I was hoping to use the built in features in autocad.

From my understanding there are two ways to export a DWG to JPG in autocad. Through the 'jpgout' command (export) and to use the DWG to JPEG plotter. Here are my problems with those ways:

1) From what I have read, autocad only supports raster image output at 100 dpi. The help articles tell you to change the paper size to change the dpi? I don't understand that, as the DPI would stay constant and your just changing the paper size... so at 640x480 pixels your still at 100 dpi and if you change your paper size to 1600x1280 pixels, your still going to have 100 dpi... am I missing something here?

2) The 'jpgout' command always outputs the screen display, no matter what I do... any ideas here? I have tried, limits, viewports, etc.

Thanks.

Understanding dpi resolution with the Raster File Formats HDI plotter driver
http://usa.autodesk.com/adsk/servlet/ps/item?siteID=123112&id=2880522&linkID=9240617
and
http://www.dotsoft.com/procedures.htm#PlotToRaster

or explore RASTERDPI command in AutoCAD Help (2006? and higher) for use with
EXPORT command and features (jpgout, it exports entities you grab on
screen).

or get this freebie windows driver
http://sourceforge.net/projects/pdfcreator/ (does more than just PDF output,
raster files and more).

or plot to pdf then convert the pdf in another program to a hi-res raster
file.

If an EPS file instead of a jpg file would also meet your needs, have your
tried plotting to this format?

IMHO... Enhanced WMF will translate better. Copy desired entities and
paste special into desired software.

You can also plot to JPG... we have setup the plotter wizard, and
created a JPEG_Grp--Compr.pc3 plotter, using acad 2006's HDI raster8.hdi
driver.

I'm always using this http://www.autodwg.com/DWG2Image/
All I need is JPEG images and sometimes Tiff, there are may settings and it is easy to use this converter, you can just try it.
