合并两个tiff文件 [英] Merge two tiff files

问题描述

你好朋友，



我有一个要求，合并两个tiff文件。问题是当合并一个tiff与其他时，我必须给一个位置其他tiff图像。

假设我有一个tiff有100个图像和5个图像中的其他图像。当我合并这两个tiff并且我给出一个位置20，那么新的tiff应该包含来自tiff 1的图像从1到20然后是tiff 2到25的图像以及来自tiff 1的26到105张图像。





提前致谢。

推荐答案

您可以使用三个 System.Drawing.Bitmap 对象来执行此操作：http://msdn.microsoft.com/en-us/library/system.drawing.bitmap.aspx [ ^ ]。< br $>


通过 Bitmap 构造函数读取两个文件，并创建一个新文件位图所需大小的实例。在目标上绘制两个源位图。对于绘图，从目标位图创建 System.Drawing.Graphics 的实例，使用 System.Drawing.Graphics.DrawImage中的一个绘制方法：

http://msdn.microsoft.com/en-us/library/system.drawing.graphics.aspx [ ^ ]。



将目标位图保存为TIFF：

You can do it using three System.Drawing.Bitmap objects: http://msdn.microsoft.com/en-us/library/system.drawing.bitmap.aspx[^].

Read two files by the Bitmap constructor, and create a new Bitmap instance of required size. Draw two source bitmaps on the target one. For drawing, create an instance of System.Drawing.Graphics from the target bitmap, draw using one of the System.Drawing.Graphics.DrawImage methods:
http://msdn.microsoft.com/en-us/library/system.drawing.graphics.fromimage.aspx[^],
http://msdn.microsoft.com/en-us/library/system.drawing.graphics.aspx[^].

Save the target bitmap as TIFF:

myBitmap.Save(outputStream, ImageFormat.Tiff);
