当我运行我的应用程序时,我的脸上出现了以下错误“GDI+ 中发生了一般错误。” 我环顾四周,看到人们有类似的错误,但没有找到真正的解决方案,或者实施起来真的很痛苦。那些没有得到解决方案的人还没有发布他们的代码。
所以我想我不妨试一试,并提出另一个关于如何修复此错误的线程。这是我的代码和错误
Random r = new Random();
DirectoryInfo di = new DirectoryInfo(folderbrowser.SelectedPath);
FileInfo[] fi = di.GetFiles().Where(f => extensions.Contains(f.Extension.ToLower())).ToArray();
for (int i = 0; i < imageCount; i++)
{
int img1 = r.Next(imageCount);
int img2 = r.Next(imageCount);
while (img2 == img1)
img2 = r.Next(imageCount);
pic1.Image = Image.FromFile(fi[img1].FullName);
pic2.Image = Image.FromFile(fi[img2].FullName);
Image i1 = pic1.Image;
Image i2 = pic2.Image;
Bitmap bitmap = new Bitmap(i1.Width + i2.Width, 1080);
using (Graphics g = Graphics.FromImage(bitmap))
{
g.DrawImage(i1, 0, 0);
g.DrawImage(i2, i2.Width, 0);
}
bitmap.Save(@"C:\TEST\Image_"+i.ToString());
}
这是错误代码

那么你们在 StackOverflow 有什么想法。我是不是和其他人一样,必须输入一个非常复杂的代码来解决这个问题,还是我犯了一个简单的错误并且很容易纠正?
如果您想自己测试它是否有帮助,这里是调试构建的链接
只需勾选“使用多个文件”,例如选择一个包含图像文件的文件夹(C:\Users\Public\Pictures\Sample Pictures)。点击合并。
我想补充一点,我在这个函数中使用了 Bitmap.Save,它可以完美地工作。
Bitmap bitmap = new Bitmap(pic1.Image.Width + pic2.Image.Width, 1080);
using (Graphics g = Graphics.FromImage(bitmap))
{
g.DrawImage(pic1.Image, 0, 0);
g.DrawImage(pic2.Image, pic1.Image.Width, 0);
}
if (savepicfile.ShowDialog() == DialogResult.OK)
bitmap.Save(savepicfile.FileName);
在上面的函数文件中是这样加载的:
DialogResult result = pic1file.ShowDialog();
if (result == DialogResult.OK)
pic1.Image = Image.FromFile(pic1file.FileName);
值得一提的是“picX”是一个“System.Windows.Forms.PictureBox”对象。
