Methods
CacheData()
Menyembunyikan data dan memastikan tidak ada pengisian data tambahan akan dilakukan dari Aspose.Imaging.DataStreamSupporter.DataStreamContainer.
public abstract void CacheData()Examples
Contoh berikut menunjukkan bagaimana caching gambar mempengaruhi kinerja.Secara umum, membaca data cache dilakukan lebih cepat daripada membaca data yang tidak cache.
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)
Dikatakan ketika kontainer aliran data berubah.
protected virtual void OnDataStreamContainerChanging(StreamContainer streamContainer)Parameters
streamContainer StreamContainer
Kontainer yang mengalir.
ReleaseManagedResources()
Pastikan tidak ada sumber daya yang tidak dikelola yang dilepaskan di sini, karena mereka mungkin sudah dilepaskan.
protected override void ReleaseManagedResources()Save()
Menyimpan data objek ke Aspose.Imaging.DataStreamSupporter saat ini.
public virtual void Save()Save(Stream)
Menyimpan data objek ke arus yang ditentukan.
public void Save(Stream stream)Parameters
stream Stream
Aliran untuk menyimpan data objek ke.
Save(String)
Menyimpan data objek ke lokasi file yang ditentukan.
public virtual void Save(string filePath)Parameters
filePath string
jalur file untuk menyimpan data objek ke.
Save(Kekuatan, Bool)
Menyimpan data objek ke lokasi file yang ditentukan.
public virtual void Save(string filePath, bool overWrite)Parameters
filePath string
jalur file untuk menyimpan data objek ke.
overWrite bool
Jika Anda mengatur ke ‘kebenaran’ di atas menulis konten file, jika tidak ada tambahan akan terjadi.
SaveData(Stream)
Simpan data tersebut.
protected abstract void SaveData(Stream stream)Parameters
stream Stream
Aliran untuk menyimpan data ke.
