QML Image showing solid black rectangle only for bigger image dimensions
-
Hi everyone,
i am using Qt5.3 with raspbian and don't understand a behavior of the QML Image component.
My Problem:
I display images for a slideshow in fullscreen (no window).
Whenever the image dimensions are too big (roughly >2000pixel in one direction), i see a black rectangle instead of the image.
Is this some kind of limitation with the raspberry pi?
When i run the same program on my linux desktop it works.My Code:
@ Image{
id:box1
width: 800; height: 800
sourceSize.width: 1920
sourceSize.height: 1600
x: 50; y: 50
source: "pic1.jpg"
opacity: 1
fillMode: Image.PreserveAspectFit
cache: false
smooth: true
}@When i remove sourceSize or increase the value above 2500 i will get a black rectangle.
The pic1.jpg is 3456 x 2592 big.Why I need that:
I know, that a sourceSize < 2000 is enough for a screensize of 800. But i plan to show panorama images as well and let them scroll from left to right. So these images will be much bigger than 800 pixel.My system:
- desktop: qt 5.2.1
- raspberry: qt 5.3.0 (but i am not sure if it's the final or some kind of beta. Is there a way to figure that out?)
Thanks for all comments,
Ben
