Cascades Development

[JohnWS]

I have captured an image and now i am trying to display this image, it is proving very difficult for me to do.

I have created imageTracker and when the image is loaded i am made aware of this in onStateChange but when i try to display the loaded image it is always blank, I have changed the imageView size and it does indeed go smaller on the screen but still blank.

I know the filename I am giving to imagetracker is ok (adding file://) because if i change it to something else onStateChange code doesn't get called.

I have been at this simple task for a few hours now so somebody please help me if you can.

void App::onStateChanged(bb::cascades::ResourceState::Type state)
{
    if(state == bb::cascades::ResourceState::Loaded)
    {
    	mImage = ImageView::create();
        mImage->setImage(mImageTracker->image());
        mImage->setMaxWidth(500);
        mImage->setMaxHeight(500);

        Page *page = new Page();
        
        	page->setContent(mImage);
        	
        	mRoot->pop();
        	mRoot->push(page);
    }
}

Try putting your image inside Container

Thank you for your reply.

I have tried the way I posted and also first putting the ImageView in a container and setting the container as content but neither show the image.

Can somebody please tell me why on earth can't I see a simple jpg I have just captured on a page in navigationPane?

I have been at this for hours and still all I get is a blank square where I should be seeing the image. 

I think I understand what I should be doing (onStateChanged see above) but I get black square when I setImage().

Anyone Please?

bump!

ImageView only handles images with dimensions less than 2048.  your photo is probably larger than this.

(to clarify, it is the max size of a texture supported by the GPU if I am not mistaken)

This thread has sample code on resizing the image using QImage.
