Image.FromFile("1.jpg") 'Parameter is not Valid'

I'm uing the code below to resize an Image. This works well when the JPG has a name other than a simple number. If I try to use 1.jpg, 2.jpg etc.. I get an error 'Parameter is not Valid'.

Anyone know why this is, does the filename need to be in a certain format? Can anyone suggest another method of loading the file.

Thanks

Thanks. How would this work with PNG or BMP files, as the files could be of any image file type.

Also, it seesm that this code doesn't preserve the aspect ratio of the image, it will always results in a stretched image.

Just change something in the code;

using System.Drawing.Imaging;
using System.Drawing.Drawing2D ;

...
private void SavePhotoAndResize(string filepath_SOurce, string filepath_DEstination, int wid, int hig)
{
FileStream stream1 = null;
Image imgTmp = null;
stream1 = new FileStream(filepath_SOurce, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);

imgFoto.Dispose();
imgTmp.Dispose();

Ok, but I'm still not having the apsect ratio preserved, the image gets distorted as the width and height are forced to the set params. If you look in the old code, the aspect ratio gets preserved, as the params are only the max allowed width/height, rather than the actual width/height.

yes

oh, merge your code with the aspect ratio preserved.

>> 'Parameter is not Valid' ?
try putting @ before the file
Image.FromFile(@"1.jpg")

or put exactly the real path
Image.FromFile("c:\\1.jpg")

Ok, it seemed the problem was with the aspect ratio preservation part of the code. Because the IntNewWidth was involved in a calculation invloving integers, it was always returning '0', so the error was thrown by the BitMap creation, as it was trying to create a BitMap with a width of 0. Here is the new code.

How does your code improve on what I already had, is there a benefit in using the code you provided, instead of my original code?

            imgTmp = Image.FromStream(stream1, false, false);
            System.Drawing.Bitmap imgFoto = null;

            int intNewWidth = 0;
            int intNewHgt = 0;
            // new width/height 
            float sglSize = 0;
            

            if ((imgTmp.Width / intMaxWidth) > (imgTmp.Height / intMaxHgt))
            {
                sglSize = imgTmp.Width;
                intNewWidth = intMaxWidth;
                intNewHgt = imgTmp.Height * (intMaxWidth / (int)sglSize);
                if (intNewHgt > intMaxHgt)
                {

Great;
Actually I don't know the real benifit, I way I see are both fine, converts any image to jpg, resize any image to wanted size.

Ok, then removed it to work fine.
if (intNewHgt > intMaxHgt)
                {
                    ////intNewWidth = intNewWidth * (intMaxHgt / intNewHgt); //removed
                    intNewHgt = intMaxHgt;
                }
            }

            {
               
                sglSize = imgTmp.Height;
                intNewHgt = intMaxHgt;
                intNewWidth = (int)((decimal)imgTmp.Width * ((decimal)intMaxHgt / (decimal)sglSize));
