bjoerka Posted March 12, 2014 Share Posted March 12, 2014 i always get an error when using the render bitmap tool. no matter if rendering is set to opengl or any renderworks setting. see the attached screenshot. dpi is set to 72 using the normal render menu works as it should be. is that a known bug?

Vectorworks, Inc Employee Dave Donley Posted March 12, 2014 Vectorworks, Inc Employee Share Posted March 12, 2014 Hello bjoerka: What is the layer scale set to? Is the marquee rectangle very large relative to the page? Quote Link to comment
bjoerka Posted March 12, 2014 Author Share Posted March 12, 2014 The layer scale was set to 1:50 The marquee rectangle is rather small compared to the whole screen. You can see the size in the new screenshot. This size starts to render when i lower the dpi setting under 24dpi! Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted March 12, 2014 Vectorworks, Inc Employee Share Posted March 12, 2014 When it does render, what are the dimensions in pixels of the bitmap created, which you can see in the Obj Info palette shape pane? Quote Link to comment
bjoerka Posted March 12, 2014 Author Share Posted March 12, 2014 (edited) It doesn?t even start to render. The dialog appears directly after releasing the mouse ;-) but... when i set the dpi to 20 a size of what you can see in the screenshot show up with 7600px by 8000px in 32bit... strange. the screen resolution is set to 1920x1200px Edited March 12, 2014 by bjoerka Quote Link to comment
bjoerka Posted March 12, 2014 Author Share Posted March 12, 2014 Just another test... 5dpi set for the render bitmap tool image size generated 12500px by 7850px ! Quote Link to comment
bjoerka Posted March 14, 2014 Author Share Posted March 14, 2014 any news to this behaviour? Quote Link to comment
Kevin McAllister Posted March 14, 2014 Share Posted March 14, 2014 Are you using a retina Macbook Pro? I suspect it might be related to the way the system scales the resolution of the display. This may be confusing what VW is generating. KM Quote Link to comment
bjoerka Posted March 15, 2014 Author Share Posted March 15, 2014 Of Course i do. But while working in the office, i use an external display as my primary and keep the macbookpro topcase closed. So i testes it now with my macbook retina display again and the result is the same. It seems that VW doesn?t recognize that the external display is running with a different resolution. And of course the dpi settings (to me) seem to work as a multiplier.... Maybe someone from the staff can say something to that.. bjoern Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted March 17, 2014 Vectorworks, Inc Employee Share Posted March 17, 2014 It doesn't use the Retina size to determine the bitmap size in pixels, only the page size. I suspect your page is very small relative to the model. The layer scale determines this, are you sure it isn't set to something like 1:1? Quote Link to comment
bjoerka Posted March 19, 2014 Author Share Posted March 19, 2014 you are right. was set to 1:1 but where is the fault? Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted March 20, 2014 Vectorworks, Inc Employee Share Posted March 20, 2014 The render bitmap tool's DPI is relative to the page, so that you can generate 300 DPI renderings multiple times, for example. If it were relative to the document window size or something else then the results would change depending on what zoom level you are currently at, which is not as predictable as doing it relative to the page. We used to have limits from MacOS of a width of 4096 pixels but now we go ahead and try to make the bitmap as large as is requested, so then free memory is the limit. Quote Link to comment
