ios - Rendering the layer of a UIWebView that contains an SVG file -

-

i attempting use method i've constructed save layer of uiwebview image. working svg have loaded uiview not getting rendered in image, background of uiwebview.

+ (bool)imagefromsvginwebview:(uiview *)theview usepng:(bool)usepng; {       uigraphicsbeginimagecontext(theview.frame.size);     [theview.layer renderincontext:uigraphicsgetcurrentcontext()];     uiimage *layerimage = uigraphicsgetimagefromcurrentimagecontext();     uigraphicsendimagecontext();     nsdata *layerimgdata = nil;     nsstring *pathcomponent = nil;     if (usepng) {         layerimgdata = uiimagepngrepresentation(layerimage);         pathcomponent = @"png";     }else {         layerimgdata = uiimagejpegrepresentation(layerimage,1.0f);         pathcomponent = @"jpg";     }     nsstring *appfile = [[ccfilemanagement conversionsdirectory] stringbyappendingpathcomponent:string(@"img.%@",pathcomponent)];     nserror *error = nil;     bool returnbool = [layerimgdata writetofile:appfile options:nsdatawritingatomic error:&error];     if(error != nil)         ilogplus(@"%@",error);     return returnbool; }

in summary, i've loaded svg uiwebview, saved uiwebview image, opened image , image not have svg in it. have done other views successfully, different svg or uiwebview.

update: if add delay make app wait few seconds execute image saving code works. putting code in webviewdidfinishload not work. webviewdidfinishload doesn't count svgs.

i have found if add .1 second delay work

- (void)webviewdidfinishload:(uiwebview *)webview; {     [self performselector:@selector(postloadactions:) withobject:webview afterdelay:0.1f]; }   - (void)postloadactions:(uiwebview *)webview; {     if (![ccconversion imagefromsvginwebview:webview usepng:yes]) {         ilogplus(@"didn't work");     }     nsarray *array = [[nsfilemanager defaultmanager] contentsofdirectoryatpath:[ccfilemanagement conversionsdirectory] error:null];     ilogplus(@"%@",array);     //[webview removefromsuperview];     [webview release];      uiimageview *imageview = [[uiimageview alloc] initwithimage:[uiimage imagewithcontentsoffile:[[ccfilemanagement conversionsdirectory] stringbyappendingpathcomponent:@"img.png"]]];     imageview.frame = cgrectmake(90, 90, imageview.frame.size.width, imageview.frame.size.height);     imageview.backgroundcolor = [uicolor clearcolor];     [self.view performselector:@selector(addsubview:) withobject:imageview afterdelay:2.0f];     [imageview release]; }

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
