i’m Back, i think that i find the solution

Use the Add-a-Plotter wizard (PLOTTERMANAGER) to add a raster “printer” – eg. for the TIFF format: use This Computer, select Raster File Formats (as Manufacturer) and under Model select TIFF (or PNG, JPG…).

Raster image size is unitless (in pixels, not inches or mm) – to increase resolution of the raster file (in pixels) set a “larger paper size”. You can create a custom “paper” size for this “printer” – increase this paper size to achieve higher resolution (more pixels in the resulting raster file). The DPI (dots-per-inch) value is usually fixed (e.g. 100 dpi) so to get 2000 pixel resolution you will have to set 2000/100 = 20 inches page size. In higher AutoCAD versions you can use directly pixels so you don’t need to recalculate page size values.

Under Device settings you can set the color depth (for color formats) – fewer colors means smaller files.

You can also export DWGs to other raster formats – CALS, JPG/JPEG, BMP, PNG, TGA, PCX. All standard print settings (line weights, plot styles…) will apply. And you can also use standard AutoCAD batch plot operations for these exports.

Please note that you cannot control resolution/quality for the direct JPGOUT, PNGOUT and similar commands.

Hello
What’s WMF extention ? and with witch logiciel can we open it, may be with ILLUSTRATOR ? cause it’s a good vectors logiciel ? i also work with vectors but the ewtention used are Eps and Ai format.

for answering to the probleme of exportation of Jpeg on CAD i think that i’ll try to export on TIFF format or PNG, but when saving i think that we have to look for “saving settings button” on the “saving window” to give good resolution to the photo (not less than 300 dpi) for print ! and then i think that it will be ok.

P2 01: i still didnt try it because i’m not on my work pc.

Ps 02 : Sorry for my bad inglish

Have you thought ot exporting as WMF? It’s a vector format. How do you usually create high resolution images from other software?

I need to create a VERY high resolution JPG/PNG from my AutoCAD. I have AutoCAD 2012. There have been many suggestions placed in the main article and in the comments, so what would be the best method if high resolution is a requirement?

Taking screenshots is not going to do it for me.

The best PDF is CutePDF, it allows custom PostScript sheet size, 100% free. Two files to install.

The only thing I would say is try to avoid JPG’s for anything other than a draft presentation. The problem is if you ever bring a JPEG back into a program like GIMP or Photoshop and edit and then resave the file as a JPEG it compresses it yet again. I think you loose about 20-30% of quality with each save. It’s always a good idea to keep a copy of anything you do in PNG or TIFF format as they’re both lossless formats (they preserve the detail and have very little pixelation). That’s why Patrick Davis’ presentain could be blown up so much and still look good. JPEGs can’t handle this. Also TIFFs are good if you wish to keep your alpha channels and layer information but the files can be very large. PNGs preserve transparency and are quite small but same quality as TIFFs.

Hope that helps someone. It sure helped me when it was first explained to me.

I personally have used M-Color by Motive Systems ( http://www.m-color.com/ ) for years now. It creates PDF’s, JPG’s, and other format and does so by importing your CTB file so it knows your lineweights, colors, etc. It also works similar to Impression, but without all the bugs found in Impression so you can do color fills, gradients and image fills and does them independent of the line colors. It allows for the layers to be arranged in order for you can arrange how things are displayed on top of each other. It reads your paperspace and so can create the images or PDF’s at the correct paper size, it understands scaling and the scale differences between plotting from Model Space as compared to Paper Space.

Recently we needed a Powerpoint presentation of a powerplant 3D assembly we had created, showing the different steps involved in installation of the modules. I exported each of the drawings to Adobe Acrobat PDF, using 11X17 layout. Then in Acrobat, I saved each of the pdf’s to png’s, using the SAVE AS feature and scrolling down to PNG. The resolution was so good that the presentation blown up to eight feet tall was excellent. We then made posters of the same PNG’s, and I was amazed at the clarity of the finished product.

Quick, easy, remarkably clear png’s with no fuss.
