#DXF to GIF conversions
8 messages in this thread
What is a suggested method to rasterize an AutoCad drawing.
I need the pictures in a bitmap format – like GIF or PCX. They exist as
AutoCad drawings, but my contact who does AutoCad is having a lot of trouble
finding a conversion route. He also is having trouble hitting the image size I
want (in pixels). (His paper copies look great.)
(We have about 50 to do – we'd like it to be a "turn the crank" operation.)
I'm planning to do some size reductions, adding gray scale elements, but if
there is a better way to get the anti-aliasing done, I'd love to hear about
that.

Howdy Charles. Depending on which release of AutoCAD you're using, there may be
some built-in methods of doing this.
In release 12, you can use the PLOT command after you have configured ACAD for
the raster file format you need. Use Raster Output Filer formats in the CONFIG
command, at which point you will be presented with numerous common raster
formats including BMP, PCX, TGA, etc. Whatever's in the display screen will
raster out according to your configured resolution (set in the PLOT
configuration). Simply PLOT the drawing, once your plotter is set to the raster
file output format and viola!
There is also a SAVEIMG command you can use internal to the ACAD session which
will allow you to save the entire screen , graphics area only, etc. in TGA,
RND, or GIF format.
In ACAD R12 Windows, a simple press of PRINT SCREEN sends the current screen
into the clipboard buffer, which can then be pasted (using Paintbrush or other
paint tools) into a raster program and saved as BMP, PCX, etc.
For Release 11 and earlier, you need to find a screen capture utility (many
available in GO GRAPHSUPP forum, most require your screen to be in standard IBM
VGA mode to capture properly.
Hope this helps for starters. -dave
YOu might also try Hijaak Pro, it can convert anything to anything, almost.

Yeah, that's a good one too. I was trying to suggest some internals to ACAD
though… see if that's what he needed before spending more. 🙂 -dave

Charles,
in addition to Dave's comments:
I found it most useful to plot from AutoCAD to TGA files for later use in
3DS. Both the PCX and the TIFF output of AutoCAD's raster file 'plotter'
driver are … let's say 'strange' <g>.

Wow dudes, thanks a lot, so prompt and an assortment of ideas about Autocad
rasterization to chew on.

ANOTHER APPROACH TO MOVING FILES FROM AUTO CAD TO ANIMATOR PRO IS TO SAVE THE
FILE IN THE AUTOCAD SLIDE FORMAT (SLD EXTENTION). THEN USE THE CONVERSION
PROGRAM WHICH COMES WITH ANIMATOR PRO (ANICONV) OPEN THE FILE BY SELECTING THE
FLIC / LOAD / OTHER / R SLD OPTION, THEN CONVERT IN THE USUAL WAY. YOU MUST GO
THROUGH THE FLIC LOAD MENU IT CAN'T BE DONE FROM THE PIC LOAD MENU.
