CCRenderTexture issue with size

cocos2d-x C++
#1

Hello.

I’m using following code:

auto renderTexture = new CCRenderTexture();
renderTexture->initWithWidthAndHeight(1024, 1024, CCTexture2DPixelFormat::kCCTexture2DPixelFormat_RGBA8888);
renderTexture->begin();
...visit some sprites...
renderTexture->end();
renderTexture->saveBuffer(kCCImageFormatPNG, "image111.png");

After executing this code I get image “image111.png” with size 1024x1024, BUT only 640x960 is filled (I use retina mode). i.e. image is cropped by the size of viewport (960x640). How can I fix this issue? Is it possible?

Sorry for awful english. Thanks.

According to this topic
http://www.cocos2d-iphone.org/forum/topic/1384
this problem was fixed in cocos2d (and the same code, that is shown in this topic, can be seen in cocos2d-x)

But, nevertheless, this problem is still open in cocos2d-x…

Did you mean #511?
I don’t think they are the same problem.

Thanks for reply.
Yes, it seems, my problem and #511 are not the same problems.

Here is my problem. I have CCRenderTexture with size 1024x1024, and drawing on CCRenderTexture is cropped to the device screen width and height (640x960). Is it possible to draw on CCRenderTexture without that cropping?

Hi Slava,
did you solve it?
