将动画 .gif 文件转换为 .bmp 条 [英] Converting animated .gif file into a .bmp strip

问题描述

我想知道是否有人可以指导我或指导我使用 .gif 图像并将其转换为 .bmp 条形图像文件.

I was wondering if someone can direct me or guide me in order to use a .gif image and convert it into a .bmp strip image file.

推荐答案

首先，您需要获取 gif 的大小.然后你需要找出有多少帧.

First, you need to get the gif's size. Then you need to find out how many frames there are.

之后，您需要创建一个高度 = 原始高度，宽度 = 帧数 * Gif 宽度的新图像.

After that you need to create a new image with Height = original height, and Width = Frames * Gif Width.

然后您必须像这样将原始 Gif 的帧粘贴到条带中:帧 N 从像素 N*宽度开始.

Then you must paste the original Gif's frames into the strip like so: Frame N starts at pixel N*Width.

也就是说，如果您要制作水平条.

That is if you're making a horizontal strip.

这是控制台应用程序的完整代码:

And here is the complete code for a console application:

using System.Drawing;
using System.Drawing.Imaging;

foreach (var arg in args)
    {
        Image gif = Image.FromFile(arg);
        FrameDimension dim = new FrameDimension(gif.FrameDimensionsList[0]);
        int frames = gif.GetFrameCount(dim);

        Bitmap resultingImage = new Bitmap(gif.Width * frames, gif.Height);

        for (int i = 0; i < frames; i++)
        {
            gif.SelectActiveFrame(dim, i);

            Rectangle destRegion = new Rectangle(gif.Width * i, 0, gif.Width, gif.Height);
            Rectangle srcRegion = new Rectangle(0, 0, gif.Width, gif.Height);

            using (Graphics grD = Graphics.FromImage(resultingImage))
            {
                grD.DrawImage(gif, destRegion, srcRegion, GraphicsUnit.Pixel);
            }
        }

        resultingImage.Save("res.png", ImageFormat.Png);
    }

生成的图像以 res.png 名称保存在编译后的控制台应用程序二进制文件目录中.您可以让应用程序将生成的图像保存在源文件所在的位置，询问是制作水平条还是垂直条等.

The resulting image is saved in the compiled console app binary file directory under the name res.png. You can make the app save the resulting image right where the source file is, ask whether to make a horizontal or vertical strip, etc.
