动画GIF(图形交换格式)在单个文件中包含特定顺序的许多图像帧。这些帧按顺序显示以创建动画。当您需要将动画GIF转换为其他多页或光栅图像格式时,可能会有各种用例。多页格式包括TIFF和PDF,而光栅图像可以是PNG,JPG,BMP等。 在本文中,我将向您展示如何将GIF动画图像转换为TIFF,PDF,PNG。JPG和BMP图像使用C#进行编程。 使用C#将动画GIF转换为TIFF 使用C#将动画GIF转换为PDF 使用C#提取GIF帧并将其转换为PNG 使用C#将GIF帧转换为JPG 使用C#将GIF帧转换为BMP Aspose.Imaging for .NET 一种高级图像处理控件,允许开发人员创建,编辑,绘制或转换图像。图像导出和转换是API核心功能之一,它允许在不安装Photoshop应用程序或任何其他图像编辑器的情况下保存为AdobePhotoshop®本机格式。 目前发布了Aspose.Imaging for .NET v20.5,支持从TIFF提取路径,优化Dicom格式的速度或内存,支持将可读的全帧gif导出为多页图像格式,还没使用过的朋友可以 点击下载最新版Aspose.Imaging 使用C#将动画GIF转换为TIFF TIFF是一种多页图像格式,可将多个图像保存在一个文件中。由于动画GIF还包含一系列帧,因此您可以将所有或选定的帧导出为TIFF格式。在此转换中

一、Windows服务 1、Windows服务应用程序是一种需要长期运行的应用程序,它适合服务器环境。 2、无用户界面,任何消息都会写进Windows事件日志。 3、随计算机启动而启动,不需要用户一定登录Windows。 4、通过服务控制管理器,可以终止、暂停及当需要时启动Windows服务。 二、体系结构 System.ServiceProcess命令空间 1、类继承关系: Object Component ServiceBase ServiceController Installer ComponentInstaller ServiceInstaller ServiceProcessInstaller 2、体系结构 第一部分就是服务程序。 实现系统的业务需求。 Service Control Manager(SCM)。SCM是操作系统的一个组成部分(services.exe),作用是于服务进行通信。 SCM包含一个储存着已安装的服务和驱动程序的信息的数据库,通过SCM可以统一的、安全的管理这些信息。 一个服务拥有能从SCM收到信号和命令所必需的的特殊代码,并且能够在处理后将它的状态回传给SCM。 ServiceBase:(服务程序)实现系统的业务需求。 在创建新的服务类时,必须从 ServiceBase 派生。 第二部分服务控制程序, 是一个Service Control

Exposing a List<domain objects> via an IList<interface>

Deadly 提交于 2019-12-11 04:35:21
问题 I have a private member of type List<T> where the T are rich domain objects. The domain in my application contains many methods that expect a T . I want to expose only a public property of type IList<IT> where T : IT . IT has a small footprint which is implemented by a DTO. Since I cannot cast a List<T> to IList<IT> I am resorting to using List<T>.ConvertAll in the property declaration. Is this there a better way to do this? Faster, more elegant? Edit to provide additional detail The T are a

问题 I have a List of a "complex" type - an object with a few string properties. The List itself is a property of another object and contains objects of a variety of types, as shown in this abbreviated class structure: Customer { public List<Characteristic> Characteristics; . . . } Characteristic { public string CharacteristicType; public string CharacteristicValue; } I'd like to be able to collect a List of the values of a given type of Characteristics for the current Customer, which I can do in

C# List .ConvertAll Efficiency and overhead

问题 I recently learned about List's .ConvertAll extension. I used it a couple times in code today at work to convert a large list of my objects to a list of some other object. It seems to work really well. However I'm unsure how efficient or fast this is compared to just iterating the list and converting the object. Does .ConvertAll use anything special to speed up the conversion process or is it just a short hand way of converting Lists without having to set up a loop? 回答1: No better way to find

Converting a list of ints to a byte array

问题 I tried to use the List.ConvertAll method and failed. What I am trying to do is convert a List<Int32> to byte[] I copped out and went this route, but I need to figure out the ConvertAll method... List<Int32> integers... internal byte[] GetBytes() { List<byte> bytes = new List<byte>(integers.Count * sizeof(byte)); foreach (Int32 integer in integers) bytes.AddRange(BitConverter.GetBytes(integer)); return bytes.ToArray(); } 回答1: Since you don't want a byte[][] where each integer maps to an array

( ConvertAll cannot perform a one-to-many conversion) Instead,
