QT4.8.4 : QtQuick 1.1 : images ressource management



  • Hello,
    I am devlopping a QML application.
    I would like to know if there is a difference between :

    • 2 instances loading and rendering the same image file
    • 2instances loading and rendering 2 duplicated files

    in other words:
    if img2.svg is a copy of img1.svg, are the 2 following code equivalent in term of performances and ressource consumption:

    @Image {
    id:iImg1
    source: "Images/img1.svg"
    }
    Image {
    id:iImg2
    source: "Images/img2.svg"
    }
    @
    and
    @Image {
    id:iImg1
    source: "Images/img1.svg"
    }
    Image {
    id:iImg2
    source: "Images/img1.svg"
    }
    @

    I think the second option (both Images loading img1.svg) will use less memory because of internal engine optimizations, but you would need to check that yourself to be sure.



  • OK, I just tested, and YES it is slower and memory consuming to load 2 duplicated images.

    Nice, so now we know for sure :-)
