Hy Guys,
I have a UIViewController wich has on ViewDidAppear this code:
ThreadPool.QueueUserWorkItem( delegate{
make_thumbs();
});
the make_thumbs function is:
void make_thumbs()
{
using( var ns = new NSAutoreleasePool() )
{
foreach( var c in Settings.Instance.Categories )
{
for( var i = 0; i < c.Pictures.Count;
i++ )
{
//this is the existing
bundled image path
string path =
c.Pictures[i].PicturePath;
string folder =
Environment.GetFolderPath(
Environment.SpecialFolder.Personal );
//this is the destination image
file name
string filename = Path.Combine(
folder, c.Name + i + ".png");
if( !File.Exists( filename ) )
{
UIImage img =
UIImage.FromFile( path ).Scale( 250,250 );
NSError err;
img.AsPNG().Save(
filename, true, out err );
}
}
}
}
}
The code is pretty easy, it has to load from a settings file all the
existing images, scale them to 250x250 and save them with another name.
The problem is that on the device ( teste on an iPhone 3g and an iPad ) it
crushes after a while with memory warnings.
