BufferSizeHint
Riceve o impone l’indice di dimensione del buffer che è definito il massimo di dimensione consentita per tutti i buffer interni.
public int BufferSizeHint { get; set; }Valore di proprietà
Examples
L’exemple ci-dessous montre comment définir une limite de mémoire lors du chargement d’une image CMX. La limite est la taille maximale autorisée (en megabytes) pour tous les buffers internes.
string dir = "c:\\aspose.imaging\\issues\\net\\3419\\";
// Setting a memory limit of 10 megabytes for a target loaded image.
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "example.cmx", new Aspose.Imaging.LoadOptions() { BufferSizeHint = 10 }))
{
image.Save(dir + "output.png",

}ConcurrentImageProcessing
Obtenez ou définissez une valeur indiquant si [traitement d’image concurrentiel].
public bool ConcurrentImageProcessing { get; set; }Valore di proprietà
DataBackgroundColor
Obtenez ou définissez le Aspose.Imaging.Image en arrière-plan _www.Color.
public Color DataBackgroundColor { get; set; }Valore di proprietà
Remarks
Di solito il colore di sfondo viene impostato ogni volta che il valore del pixel non può essere recuperato a causa della corruzione dei dati.
DataRecoveryMode
Riceve o impone il modo di recupero dei dati.
public DataRecoveryMode DataRecoveryMode { get; set; }Valore di proprietà
ProgressEventHandler
Riceve o mette il progresso degli eventi.
[JsonProperty]
public ProgressEventHandler ProgressEventHandler { get; set; }Valore di proprietà
Examples
L’exemple ci-dessous montre comment imprimer des informations sur les événements de progrès pour les opérations de chargement/exportation.
public void Test3460()
{
string dir = "c:\\aspose.imaging\\net\\issues\\3460";
string fileName = System.IO.Path.Combine(dir, "big.png");
// Example of use of separate operation progress event handlers for load/export operations
