I hope the new version addresses this issue because is kind of annoying. gto234 2010-09-09 00:16:29 http://www.zwsoft.com/forum/viewthread.php?tid=1202&pid=12906 Thanks for the quick reply. Even with the option "Zoom and pan with raster &amp; OLE" turned off it is still very slow. Are you going to release an update to fix this problem for 2010 or I have to buy the 2011 ver?I say this because I just bought the 2010 ver. and I have to say that I am kind of disappointed about the way it processes raster images. P.S. If you want I can send you some of the rasters (1-10 mb) that i use, in order to see what is the exact problem because with small images (100-200kb) there is no problem. gto234 2010-09-07 16:47:44 http://www.zwsoft.com/forum/viewthread.php?tid=1202&pid=12902 I have the same problem with Zwcad 2010. I use some tiffs as background of my cad project and the zooming and paning is very very slow compared to Autocad. Is there any plan to improve this? gto234 2010-09-06 18:19:12 http://www.zwsoft.com/forum/viewthread.php?tid=1202&pid=11059 Dear Jenny, Thank you that's a real big improvement in speed for me. Also you can unload the pictures temporary (a workaround). I have a question about the next version. Is it free, like a update for the people who have bought a usb-stick (version 2008i)? Beste regards, Nathantheone nathantheone 2008-08-23 14:37:08 http://www.zwsoft.com/forum/viewthread.php?tid=1202&pid=11046 Dear helpdesk, When working with cad files with a couple of pictures included (jpg). ZWcad responses very slow at zooming and paning (i used this with the middle mouse option mbuttonpan=1!) Is there anyway to solve this problem? The dwg is about 1,5MB and the 8 pictures are 600kB each. When I detache the pictures then zwcad is fast again. The problem only accurse when zooming out (zoom extended). Not when I am zooming already in detail. Then its fast again. I tested this with a couple of dwg's all with pictures and they all had the same problem. Is this a bug? Or can I do something about that? Nathantheone nathantheone 2008-08-05 15:43:40
