Aspose.Imaging for .NET一種高級圖像處理控件，允許開發(fā)人員創(chuàng)建，編輯，繪制或轉(zhuǎn)換圖像。圖像導出和轉(zhuǎn)換是API核心功能之一，它允許在不安裝Photoshop應用程序或任何其他圖像編輯器的情況下保存為AdobePhotoshop®本機格式。

事實證明，Aspose.Imaging是處理各種圖像格式的強大API。除單頁圖像外，Aspose.Imaging還支持處理多頁圖像，包括GIF，TIFF，PSD，DICOM，CDR和WebP。

近期發(fā)布了Aspose.Imaging for .NET v20.3，新增支持導出為DICOM文件格式和BMP文件格式的RLE8壓縮，優(yōu)化Tiff tile loaders，修復多處轉(zhuǎn)換異常，還沒使用過的朋友可以點擊下載最新版Aspose.Imaging

新增與改善

新功能用法示例

IMAGINGNET-3619支持導出到DICOM FILEFORMAT

//DICOM file format

//Digital Imaging and Communications in Medicine is the standard for the communication and management of medical imaging information. DICOM is most commonly used for storing and transmitting //medical images in medical devices such as scanners, servers, printers and picture archiving and communication systems (PACS). DICOM is used worldwide to store, exchange, and transmit //medical images.

//Various programs for Windows, macOS, and Linux can view DICOM files. DICOM uses the .DCM extension. These images can also be viewed online through certain web browsers. It is only //compatible using Chrome, Opera, Firefox, and Internet Explorer with the Google Chrome Frame extension installed.
//Why to use DICOM?

//DICOM provides a well-tested and widely accepted foundation for Medical Image Management. The advantages of using DICOM:

   //Makes medical imaging information interoperable.
   //Integrates image-acquisition devices, PACS, workstations, VNAs and printers from different manufacturers.
   //Is actively developed and maintained to meet the evolving technologies and needs of medical imaging.
   //Is free to download and use.

//Convert JPEG to DICOM

//The next code sample converts JPEG image to DICOM file format:

using (var image = Image.Load("sample.jpg"))
{
   image.Save("sample.dcm", new DicomOptions());
}

//Image modifications

//You can use methods of the Image class to modify source image before export. For instance, you can resize and rotate the image:

using (var image = Image.Load("sample.jpg"))
{
   image.Resize(300, 300);
   image.RotateFlip(RotateFlipType.Rotate90FlipY);
   image.Save("sample.dcm", new DicomOptions());
}

//Convert multipage images to DICOM

//DICOM format supports multipage images. You can convert GIF or TIFF images to DICOM in the same way as JPEG images:

using (var image = Image.Load("animation.gif"))
{
   image.Save("animation.dcm", new DicomOptions());
}

//Export all DICOM pages to JPEG

//In case if you need to extract all the pages from DICOM file you can use the next code. It creates separate JPEG file for each DICOM page:

using (var image = (DicomImage)Image.Load("animation.dcm"))
{
   for (var index = 0; index < image.Pages.Length; index++) { var page = image.Pages[index]; page.Save($"Page {index}.jpeg", new JpegOptions()); } }

IMAGINGNET-3736 Aspose.Imaging 19.12創(chuàng)業(yè)許可證不適用于.webp圖像

//Bugs with using VentureLicense in Webp format fixed.

//Please, remove license before execute this example.

           string fileName = "asposenet_577_src01.webp";
           string basePath = "D:";
           string inputFileName = Path.Combine(basePath, fileName);
           string outputFileName = inputFileName + ".webp";
           using (RasterImage image = (RasterImage) Image.Load(inputFileName))
            {
               LicenseVenture(image, true);
               image.Save(outputFileName);
            }

           string fileName = "asposenet_577_src01.webp";
           string basePath = "D:";
           string inputFileName = Path.Combine(basePath, fileName);
           string outputFileName = Path.Combine(basePath, "false_" + fileName + ".webp");
           LicenseHelper.RemoveLicense();
           using (RasterImage image = (RasterImage) Image.Load(inputFileName))
            {
               image.Save(outputFileName);
            }

IMAGINGNET-3534 支持BMP文件格式的RLE8壓縮

 string inputFilePath = "1.bmp";
           using (BmpImage image = (BmpImage)Image.Load(inputFilePath))
           {
               // PDF
                PdfOptions pdfExportOptions = new PdfOptions();
                pdfExportOptions.PdfDocumentInfo = new Aspose.Imaging.FileFormats.Pdf.PdfDocumentInfo();

                image.Save("1.pdf", pdfExportOptions);

               // PNG
                PngOptions pngExportOptions = new PngOptions();
                image.Save("1.png", pngExportOptions, new Rectangle(28, 28, 200, 200));
           }
