hi.i want to get data from a hand-drawing to cad by inserting it as a jpeg.unfortunately the resolution in cad is much worse than the original resolution.is it not possible to adjust the resolution displayed on the screen (it is not about printing)?i read that the resolution is better if i insert it as an ole object. unfortunately jpegs cannot be displayed as ole objects (only a frame with the path...) and if i convert the jpeg to bitmap the resolution gets worse also :-(any ideas?thanks!cheersnickoh

That's life.  You can't always get what you want.  In your case this refers to better resolution of your JPG.  Might try a PNG file but I wouldn't hold out too much hope for it either.

It does not matter what format it is in..bmp, dip, jpg, jpeg, jpe,  jifif, gif, tiff, tif, png, or ico.The trick is the resolution before inserting it into the drawing. The higher the resolution the better the image in the drawing. Because of the limited upload size and this a 9mb you can go here to get the drawing ( https://grabcad.com/library/clear-image-inserts-1/files/not%20just%20a%20dot.dwg ) This drawing has a jpeg in that has been scaled down to only 0.0003 high but if you zoom in on it (at the tips of the arrows) you find it very clear. It's Pixels are at  1920W and  1200H. I know this is extreme but I put the same Jpeg in at 300 by 187 and you can see it is not clear at all at true size.You can scale the jpeg at the tips of the arrows to any size you need and it will still be clear.If you have a way of getting a better pic. of any kind it will help you view it in AutoCAD

nick: Clue us in.  How did you create the JPG of the hand drawing?  Was it scanned or photographed?  That will have some bearing on the resolution.

There's a big difference between a raster file and a vector file.  Your JPG image is a raster file... a file of pixels.  Your drawing file is a vector file, and no matter how big you blow it up or reduce it the "resolution" so to speak will stay the same.  The raster file on the other hand will rapidly loose resolution and sharpness the more you blow it up because it always retains the same number of pixels.  And the further you separate them from one another the further back away from it you have to stand to make our what you're looking at.I hope this explanation helps you understand what is going on when you insert any type of image file into an AutoCAD drawing.Dave.
