getContentSize() bug

[rudiHammad]

Hi,
I am new to axmol but I had a project in cocos2dx that I am migrating and I am noticing some issues I don't think I had before.
For instace, I create a square spritge of an image with a resolution of 50 * 50 and they a check the content size as usual with

auto test = ax::Sprite::create("redRect.png");
addChild(test);
auto size = test->getContentSize();
ax::log("%f, %f <<<<<<<<", size.width, size.height);

And the results are 62.5 width and 62.5 height. I can't figure out why is that. Is it a but or am I missing something?
Just in case you might think the image is not actually 50*50 here are the details

The contentSize of sprite affected by contentScaleFacotor, not the image pixel wide, if you want get the image pixel wide and height, use follow code:

auto test = ax::Sprite::create("redRect.png");
auto texture = test->getTexture();
int imageWidth = texture->getPixelsWide();
int imageHeight = texture->getPixelsHigh();

okey thanks. But what I don't understand is that I didn't change thing in the scale. It is just an 50*50 image, with nothing scaled.

Look at your project's AppDelegate.cpp file, specifically the calls to setContentScaleFactor. Put a breakpoint on the calls to that function, and you will have your answer as to why the scale factor is equal to 1.25.

If you don't want to use scaling, then just get rid of those setContentScaleFactor calls, or just make sure it's called with a value of 1. In this case you would need to make sure you set the correct ResolutionPolicy for your needs when calling glView->setDesignResolutionSize.

oh my god. Thanks.
I spent 3 hours reviewing custom tools i wrote because all my animations where out of frame. That fixed it.
Thanks for the quick response.
