In some scenarios, the plurality of images required, co (fight) becomes a synthesized effect Example:
Vertical:
Landscape:
ImageMergeOrientation enum
{
Horizontal,
Vertical
}
private void CombineImages(FileInfo[] files, string toPath, ImageMergeOrientation mergeType = ImageMergeOrientation.Vertical)
{
//change the location to store the final image.
var finalImage = toPath;
var imgs = files.Select(f => Image.FromFile(f.FullName));
var finalWidth = mergeType == ImageMergeOrientation.Horizontal ?
imgs.Sum(img => img.Width) :
imgs.Max(img => img.Width);
var finalHeight = mergeType == ImageMergeOrientation.Vertical ?
imgs.Sum(img => img.Height) :
imgs.Max(img => img.Height);
var finalImg = new Bitmap(finalWidth, finalHeight);
Graphics g = Graphics.FromImage(finalImg);
g.Clear(SystemColors.AppWorkspace);
var width = finalWidth;
var height = finalHeight;
var nIndex = 0;
foreach (FileInfo file in files)
{
Image img = Image.FromFile(file.FullName);
if (nIndex == 0)
{
g.DrawImage(img, new Point(0, 0));
nIndex++;
width = img.Width;
height = img.Height;
}
else
{
switch (mergeType)
{
case ImageMergeOrientation.Horizontal:
g.DrawImage(img, new Point(width, 0));
width += img.Width;
break;
case ImageMergeOrientation.Vertical:
g.DrawImage(img, new Point(0, height));
height += img.Height;
break;
default:
throw new ArgumentOutOfRangeException("mergeType");
}
}
img.Dispose();
}
g.Dispose();
finalImg.Save(finalImage, System.Drawing.Imaging.ImageFormat.Tiff);
finalImg.Dispose();
}
Code Description:
Horizontal or vertical images combined according to the parameters
If it is horizontal, the highest image height goes; if the longitudinal width of the widest goes
