Properties
DataStreamContainer
Pronađite protok podataka objekta.
public StreamContainer DataStreamContainer { get; }Vrijednost nekretnina
IsCached
Dobiva vrijednost koja ukazuje na to da li su podaci objekta trenutno sakriveni i da se ne zahtijeva čitanje podataka.
public abstract bool IsCached { get; }Vrijednost nekretnina
Methods
CacheData()
Čišćenje podataka i osigurava da se neće izvršiti dodatni teret podataka iz podrijetla Aspose.Imaging.DataStreamSupporter.
public abstract void CacheData()Examples
Sljedeći primjer pokazuje kako slikovni caching utječe na performanse.U općem slučaju, čitanje cache podataka obavlja se brže nego što čitaju ne-cache podatke.
string dir = "c:\\temp\\";
// Load an image from a PNG file.
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
// Cache all pixel data so that no additional data loading will be performed from the underlying data stream
image.CacheData();
System.Diagnostics.Stopwatch stopwatch = new System.Diagnostics.Stopwatch();
stopwatch.Start();
// Reading all pixels is pretty fast.
Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;
for (int y = 0; y < image.Height; y++)
{
for (int x = 0; x < image.Width; x++)
{
int color = rasterImage.GetArgb32Pixel(x, y);
}
}
stopwatch.Stop();
System.Console.WriteLine("Reading all cached pixels took {0} ms.", stopwatch.ElapsedMilliseconds);
}
// Load an image from a PNG file
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
System.Diagnostics.Stopwatch stopwatch = new System.Diagnostics.Stopwatch();
stopwatch.Start();
// Reading all pixels is not as fast as when caching
Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;
for (int y = 0; y < image.Height; y++)
{
for (int x = 0; x < image.Width; x++)
{
int color = rasterImage.GetArgb32Pixel(x, y);
}
}
stopwatch.Stop();
System.Console.WriteLine("Reading all pixels without preliminary caching took {0} ms.", stopwatch.ElapsedMilliseconds);
}
// The output may look like this:
// Reading all cached pixels took 1500 ms.
// Reading all pixels without preliminary caching took 150000 ms.OnDataStreamContainerChanging(StreamContainer)
Naziva se kada se mijenja kontejner za protok podataka.
protected virtual void OnDataStreamContainerChanging(StreamContainer streamContainer)Parameters
streamContainer StreamContainer
Kontejner za struju.
ReleaseManagedResources()
Uklonite upravljane resurse. pobrinite se da se ovdje ne otpuštaju nekontrolirani resursi, budući da su možda već otpušteni.
protected override void ReleaseManagedResources()Save()
Shrani podatke o objektu na trenutni Aspose.Imaging.DataStreamSupporter.
public virtual void Save()Save(Stream)
Shrani podatke o objektu u određenom toku.
public void Save(Stream stream)Parameters
stream Stream
U toku za spašavanje podataka objekta na.
Save(String)
Shrani podatke o objektu na određeno mjesto datoteke.
public virtual void Save(string filePath)Parameters
filePath string
Put datoteke za spašavanje podataka objekta na.
Save(Sljedeći Članak Bool)
Shrani podatke o objektu na određeno mjesto datoteke.
public virtual void Save(string filePath, bool overWrite)Parameters
filePath string
Put datoteke za spašavanje podataka objekta na.
overWrite bool
ako je postavljen na ‘pravda’ nad pisanjem sadržaja datoteke, inače će se pojaviti dodatak.
SaveData(Stream)
Sačuvajte podatke.
protected abstract void SaveData(Stream stream)Parameters
stream Stream
Proljev za spašavanje podataka na.
