示例

以下示例展示了在保存（导出）Tiff 图像之前进行批量转换。

[C#]

string fileName = "10MB_Tif.tif";
    string inputFileName = fileName;

    string outputFileNameTif = "output.tif";
    
    //已实现在保存（导出）Tiff 图像之前进行批量转换的可能性。

    using (Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = (Aspose.Imaging.FileFormats.Tiff.TiffImage)Aspose.Imaging.Image.Load(inputFileName))
    {
        // 为页面设置批量操作
        tiffImage.PageExportingAction = delegate(int index, Image page)
        {
            // 触发垃圾回收，以避免前一页产生的不必要的垃圾存储
            GC.Collect();

            ((Aspose.Imaging.RasterImage)page).Rotate(90);
        };

        tiffImage.Save(outputFileNameTif);

        /* Attention! In batch mode all pages will be released in this line!
         If you want to further perform operations on the original image, you should reload it from the source to another instance. */
    }
