Hello i Have uploaded image using ImageResizer
using this code
var instructions = new ImageResizer.Instructions
{
Width = Convert.ToInt32(Newwidth),
Height = Convert.ToInt32(Newheiht),
Format = "jpg",
Mode = ImageResizer.FitMode.Crop,
Scale = ImageResizer.ScaleMode.Both,
};
File.InputStream.Seek(0, SeekOrigin.Begin);
ImageResizer.ImageJob i = new ImageResizer.ImageJob(File, Filepath, instructions);
i.CreateParentDirectory = false;
i.Build();
i have tried using
AutoRotate = true
i still got the image rotated to horizontall
i also tried Rotate=90
the pic was rotated and lost the proportion here is how it looks like after rotate
the resized roteted picture changed it to width=296 height=437 instead of height=296 width=437
the image was taken vertically using samsung galaxy 3 buy when resized it and upload it it show horizonally
here is the original photo taken:
here is how it shown after uploaded:
回答1:
You haven't posted the diagnostics page, which lists which plugins are installed.
The most likely cause is that you didn't <add name="AutoRotate" /> or new AutoRotate().Install(Config.Current) to install the AutoRotate plugin, and therefore &autorotate=true had no effect.
It's also possible that there's a new form of image metadata that we can't detect yet, but that seems less likely.

Try Autorotate property "True"; It worked for me.
&autorotate=true
