Loading Images depending on visible will be useful for start-up time reduction

    XMLWordPrintable

Details

    Description

      As far as we tested, QML engine loads all the images referred in QMLs at its startup and makes atlas (except compressed ones) regardless their "visible" property.

      (It defers upload to GPU until one of them in the atlas gets actually rendered.)

      This behavior affects startup time of the application.

      Therefore, it will be better if we make a property to defer image loading until it gets visible and users taking care of application startup time can specify that in QML.
