BufferSizeHint
Få eller indstille bufferstørrelsen indikator, der er defineret max tilladte størrelse for alle interne buffer.
public int BufferSizeHint { get; set; }Ejendomsværdi
Examples
Følgende eksempel viser, hvordan man indstiller en hukommelsegrænse, når man oplader et CMX-billede.Memoriegrænsen er den maksimale tilladte størrelse (i megabyte) for alle interne buffer.
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",
new Aspose.Imaging.ImageOptions.PngOptions()
{
VectorRasterizationOptions =
new Aspose.Imaging.ImageOptions.CmxRasterizationOptions
{
TextRenderingHint = Aspose.Imaging.TextRenderingHint.SingleBitPerPixel,
SmoothingMode = Aspose.Imaging.SmoothingMode.AntiAlias,
Positioning = Aspose.Imaging.ImageOptions.PositioningTypes.DefinedByDocument
}
});
}Følgende eksempel viser, hvordan man indstiller en hukommelsegrænse, når man oplader et JPEG-billede.Memoriegrænsen er den maksimale tilladte størrelse (i megabyte) for alle interne buffer.
string dir = "c:\\aspose.imaging\\issues\\net\\3404\\";
// Setting a memory limit of 50 megabytes for target loaded image
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "inputFile.jpg", new Aspose.Imaging.LoadOptions() { BufferSizeHint = 50 }))

}ConcurrentImageProcessing
Giver eller indsætter en værdi, der angiver, om [konkurrent billedbehandling].
public bool ConcurrentImageProcessing { get; set; }Ejendomsværdi
DataBackgroundColor
Få eller indsæt Aspose.Imaging.Bild baggrunden WR17.Color.
public Color DataBackgroundColor { get; set; }Ejendomsværdi
Remarks
Typisk er baggrundsfarven indstillet, når pixelværdien ikke kan genoprettes på grund af datakorruption.
DataRecoveryMode
Få eller indstille data genopretningsmetoden.
public DataRecoveryMode DataRecoveryMode { get; set; }Ejendomsværdi
ProgressEventHandler
Få eller sætte fremskridt begivenhed handler.
[JsonProperty]
public ProgressEventHandler ProgressEventHandler { get; set; }Ejendomsværdi
Examples
Følgende eksempel viser, hvordan man udskriver oplysninger om fremskridtshændelser for opladning/eksportoperationer.
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
using (var image = Aspose.Imaging.Image.Load(fileName, new Aspose.Imaging.LoadOptions { ProgressEventHandler = ProgressCallback }))
{
image.Save(fileName + ".psd",
new Aspose.Imaging.ImageOptions.PsdOptions() { ProgressEventHandler = ExportProgressCallback });
}
}
private void ProgressCallback(Aspose.Imaging.ProgressManagement.ProgressEventHandlerInfo info)
{
System.Console.WriteLine("{0} : {1}/{2}", info.EventType, info.Value, info.MaxValue);
}
private void ExportProgressCallback(Aspose.Imaging.ProgressManagement.ProgressEventHandlerInfo info)
{
System.Console.WriteLine("Export event {0} : {1}/{2}", info.EventType, info.Value, info.MaxValue);
}
// The STDOUT log may look like this:
//Initialization : 1/4

Giver eller sætter en værdi, der angiver, om ICC-profilkonvertering skal anvendes.
[Obsolete("ICC profile conversion will be used by default and this property will be removed.")]
public bool UseIccProfileConversion { get; set; }Ejendomsværdi
