实施例。 在这里,“clsCanvas”对象和集合几乎可以忽略,它是我的代码内部的一个对象,它使用GDI +生成图像,然后将它们放在磁盘上。下面的代码只是展示了如何从文件中获取一堆图像并将它们组装成一个可缩放的集合。希望这可以帮助某人:-)。
CollectionCreator cc = new CollectionCreator();
// set default values that make sense for conversion options
cc.ServerFormat = ServerFormats.Default;
cc.TileFormat = ImageFormat.Jpg;
cc.TileSize = 256;
cc.ImageQuality = 0.92;
cc.TileOverlap = 0;
// the max level should always correspond to the log base 2 of the tilesize, unless otherwise specified
cc.MaxLevel = (int)Math.Log(cc.TileSize, 2);
List<Microsoft.DeepZoomTools.Image> aoImages = new List<Microsoft.DeepZoomTools.Image>();
double fLeftShift = 0;
foreach (clsCanvas oCanvas in aoCanvases)
{
//viewport width as a function of this canvas, so the width of this canvas is 1
double fThisImgWidth = oCanvas.MyImageWidth - 1; //the -1 creates a 1px overlap, hides the seam between images.
double fTotalViewportWidth = fTotalImageWidth/fThisImgWidth;
double fMyLeftEdgeInViewportUnits = -fLeftShift/fThisImgWidth; ; //please don't ask me why this is a negative numeber
double fMyTopInViewportUnits = -fTotalViewportWidth * 0.3;
fLeftShift += fThisImgWidth;
Microsoft.DeepZoomTools.Image oImg = new Microsoft.DeepZoomTools.Image(oCanvas.MyFileName.Replace("_Out_Tile",""));
oImg.ViewportWidth = fTotalViewportWidth;
oImg.ViewportOrigin = new System.Windows.Point(fMyLeftEdgeInViewportUnits, fMyTopInViewportUnits);
aoImages.Add(oImg);
}
// create a list of all the images to include in the collection
cc.Create(aoImages, sMasterOutFile);
