QTQuick Memory problem ~~~~~
Our studio using QT 5.1 dev a page editing software , Our software using QML\C++\JS for UI interface & all ,
When user create New page ( 1024 X 768 ,even 2048 x 1536 iPad ) , The page is QQuickItem , The men size will increase 20MB/ 40MB . OMG, this means the texture in each QQuickItem is pixel array? I test the AnimationSprite when i loading 800x600 72 png images (just 5MB) for out 360 degree show ， each frame mem size is 20mb . the small
test App almost 176MB mem size.
my question is : 1 . How to optimize this situation ? Is this a QT limitation ？
- When the sprite size was big than 1000X1000 and the sprite Animation more than 30 frames , ( One sprite engine combine sprite textures to one texture I saw the doc ) ,How can I achieve it 。
Thx in advance
any idear ?
If nobody here knows the answer, I recommend asking at the "Interest mailing list":http://lists.qt-project.org/mailman/listinfo/interest -- you can find Qt's engineers there, who know about Qt's memory usage.
