如何在C＃中显示指定的gif框架？ [英] How to show a specified frame of gif in C#?

问题描述

大家好

我想要显示一个gif图像的框架。我搜索并发现以下代码应该可以工作，但它不起作用。它正确检测帧数，但它显示的是gif的整个帧而不是指定的帧。我很感激任何意见。

谢谢大家。

Hi everybody
I want to show a frame of a gif image. I searched and found that the following code should work, but it doesn't work. it detects the number of frames correctly but it shows the whole frames of gif instead of the specified frame. I am grateful of any opinion.
Thanks everybody.

Image[] frames = new Image[36];
Image GG = Image.FromFile(@"C:\Users\Administrator\TEST C#\TEST2frame2\chef.gif");
FrameDimension dimension = new FrameDimension(GG.FrameDimensionsList[0]);
            // Number of frames
int frameCount = GG.GetFrameCount(dimension);
label1.Text = frameCount.ToString();

            // Return an Image at a certain index
GG.SelectActiveFrame(dimension, 1);
frames[1] = ((Image)GG.Clone());
pictureBox1.Image = frames[1];

推荐答案

你的代码看起来很奇怪。试试这里： C＃从GIF获取帧 [ ^ ]，它是工作肯定。

Your code looks strange. Try the one here: C# Get Frames from a GIF[^], it is working for sure.

嗨亲爱的Zoltan Zorgo

我做了你说的话，并将我的代码改为下面。但问题仍然存在。

我期待着你。谢谢。

Hi Dear Zoltan Zorgo
I did what you said and changed my code to below. But the problem remains as before.
I am looking forward from you. Thank you.

using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Imaging;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace TEST2frame2
{


    public partial class Form1 : Form
    {

        Image[] getFrames(Image originalImg)
        {

            int numberOfFrames = originalImg.GetFrameCount(FrameDimension.Time);

            Image[] frames = new Image[numberOfFrames];
            label1.Text = numberOfFrames.ToString();


            for (int i = 0; i < numberOfFrames; i++)
            {

                originalImg.SelectActiveFrame(FrameDimension.Time, i);

                frames[i] = ((Image)originalImg.Clone());

            }



            return frames;

        }

        public Form1()
        {
            InitializeComponent();
            Image[] frame = getFrames(Image.FromFile(@"C:\Users\Administrator\Desktop\Interface\TEST C#\TEST2frame2\chef.gif"));
            pictureBox1.Image = frame[1];

        }


    }
}
