Large image from file system with ImageView

Hi

 

Im trying to show an image from file system, eg

 

QString path="file:///accounts/1000/shared/camera/IMG_00000144.jpg" 
imageView->setImageSource(QUrl(path));

When I try with small size image file (less than 600Kb), the picture can be shown well. But whenever picture file size get to around 1MB, it just show a black screen.

 

Do you have any suggestion? Should I re-configure the ImageView?

Re: Large image from file system with ImageView

Hi,

 

ImageView can't display images larger than 2048x2048 pixels (maximum texture size).

Image can be resized using QImage class, this post has sample code for this:
