wpf - Save Image which is inside a content control -

-

i'm having content control have image inside when im trying save image im getting black image. missing.

rendertargetbitmap rtb = new rendertargetbitmap((int)content1.actualwidth, (int)content1.actualheight, 96, 96, pixelformats.pbgra32);             rtb.render(content1);              pngbitmapencoder pnge = new pngbitmapencoder();             pnge.frames.add(bitmapframe.create(rtb));             stream stream = file.create(drivename + ":/opencv/images/ui/leftedge.png");             pnge.save(stream);             stream.close();

looks contentcontrol hasn't been layouted when try render it.

try call updatelayout() on it.

if doesn't trick try calling first measure(), arrange() - before rendering.

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
