"Parameter is invalid" when creating a new bitmap pointing to a filepath


"Parameter is invalid" when creating a new bitmap pointing to a filepath

Does that help Try a fully qualified path to the image file with double backslashes ("C:\test\abc.jpg") Determine if the jpeg file is valid for .net's image codec Create jpeg in MS Paint Create jpeg in Gimp, Photoshop, ... Use imagemagick to convert the jpeg from jpeg to png and then back to jpeg Use jpegtran to optimize the jpeg to force rewriting of the jpeg header Use imagemagick's identify or gimp to determine what is in the jpeg (it could be a different image file format or jpeg 2000) In .net code, use File or FileInfo calls to verify that the file exists, has non-zero length and is acessible
If the file is on a network drive and has just been written, it may take a second or two for the file to be released from exclusive use even after the file has been closed by the creator of the file.

seems to work fine Keep in mind, that is a LOT of memory you are trying to allocate with that Bitmap.

I hope this helps . The reason is the rect you are using on the imageToMask is bigger then the bitmap itself.
code :
var rect = new Rectangle(0, 0, maksingImage.Width, maksingImage.Height);
var bitsimageToMask = imageToMask.LockBits(rect, ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb);

like below fixes the issue Micke is right, the main reason is that in 32 bit size of register is 4 byte so to optimize speed and efficiency it should be multiple of 4, Source

it should still fix some issue Creating a bitmap from an EmguImage did not work. Elected to save the image to disk, read all the bytes and then create a bitmap
