Mostly this is done by generating my images as composites of png files and using drawpicture. >From time to time I would compile them for MAC intel and this would help me >sort out slight layout improvements between the two. HOWEVER - after intalling and building since 2012.r1 I get the horrible Exception of class PlatformNotSupportedException was not handled. The application must shut down Exception message: Creating a picture with alpha channels is not supported in Carbon, use Cocoa instead. So, when I do build to Cocoa, the graphic behave horribly and I get tons of crash messages. My mac is running Lion (my earlier builds use the MBS quicktime function and work well. It works perfectly on windows) I've checked all my images (png's and jpegs) in Photoshop - they do not have alpha channels - I can only think these channels are generated when I use the p = new picture (100,100,32) command. So, my question - how do I turn off alpha channels - or disable them or is there some new fangled command which is new. I do not want to generate a MAC version in Cocoa as it (in my opinion) is horribly buggy, probably does not support ealier versions of Mac OS, and if I complie for windows (and there are no window's specific APIs or other windows only dll being used, I expect it to run just as well on Mac as it does on windows (or even better). Has any body got any device. PS I expect I will be able to iron out those cocoa bugs on the release which allows us all to work on any platform and build using our current platform (I use the professional license) Cheer, Sean Top swort Post subject: Re: Alpha channel is making my app crashPosted: Mon Nov 19, 2012 10:27 am Joined: Mon May 31, 2010 5:35 am Posts: 2246 Location: Netherlands 2012 R2 is beta.

Okay- I didn't know that - but is RS2012v1 in Beta? It shouldn't be if the next version is in Beta... and that's where all the problems started. However, 2012v2 is working well on windows S Top Display posts from previous: All posts1 day7 days2 weeks1 month3 months6 months1 year Sort by AuthorPost timeSubject AscendingDescending Page 1 of 1 [ 3 posts ]
