BufferSizeHint
接收或设置了定义为所有内部泡沫的最大允许大小的泡沫大小指标。
public int BufferSizeHint { get; set; }财产价值
Examples
下面的例子表明如何在加载CMX图像时设置内存限制 内存限制是所有内置图像的最大允许大小(兆比特)。
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
}
});
}下面的例子表明如何在加载 JPEG 图像时设置内存限制 内存限制是所有内部泡沫的最大允许大小(在 megabytes )。
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 }))
{
image.Save(dir + "outputFile_Baseline.jpg",
new Aspose.Imaging.ImageOptions.JpegOptions
{
CompressionType = Aspose.Imaging.FileFormats.Jpeg.JpegCompressionMode.Baseline,
Quality = 100
});
image.Save(dir + "outputFile_Progressive.jpg",
new Aspose.Imaging.ImageOptions.JpegOptions
{
CompressionType = Aspose.Imaging.FileFormats.Jpeg.JpegCompressionMode.Progressive
});
image.Save(dir + "outputFile_Lossless.jpg",
new Aspose.Imaging.ImageOptions.JpegOptions
{
ColorType = Aspose.Imaging.FileFormats.Jpeg.JpegCompressionColorMode.YCbCr,
CompressionType = Aspose.Imaging.FileFormats.Jpeg.JpegCompressionMode.Lossless,
BitsPerChannel = 4
});
image.Save(dir + "outputFile_JpegLs.jpg",
new Aspose.Imaging.ImageOptions.JpegOptions
{
ColorType = Aspose.Imaging.FileFormats.Jpeg.JpegCompressionColorMode.YCbCr,
CompressionType = Aspose.Imaging.FileFormats.Jpeg.JpegCompressionMode.JpegLs,
JpegLsInterleaveMode = Aspose.Imaging.FileFormats.Jpeg.JpegLsInterleaveMode.None,
JpegLsAllowedLossyError = 3,

public ProgressEventHandler ProgressEventHandler { get; set; }财产价值
Examples
下面的例子表明如何打印有关负载/出口操作进展事件的信息。
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
//PreProcessing : 2/4
//Processing : 3/4
//Finalization : 4/4
//Export event Initialization : 1/4
