C# - Parameter Is Not Valid Calling Bitmap.Save()?
Mar 22, 2011This in in an ASP.NET application.
Locally, this code runs fine, but on our production server, it throws an exception of 'Parameter is not valid' when Bitmap.Save() is called.
Should I not be using System.Drawing.Bitmap because its not recommened based on this:
[URL]
Classes within the System.Drawing namespace are not supported for use within a Windows or ASP.NET service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions.
What else could I use?
Bitmap myBitmap = new Bitmap(img);
myBitmap.SetResolution(img.HorizontalResolution, img.VerticalResolution);
// get the tiff codec info
ImageCodecInfo myImageCodecInfo = GetEncoderInfo("image/tiff");
// Create an Encoder object based on the GUID for the Compression parameter category
System.Drawing.Imaging.Encoder myEncoder = System.Drawing.Imaging.Encoder.Compression;
// create encode parameters
EncoderParameters myEncoderParameters = new EncoderParameters(1);
EncoderParameter myEncoderParameter = new EncoderParameter(myEncoder, (long)EncoderValue.CompressionCCITT4);
myEncoderParameters.Param[0] = myEncoderParameter;
// save as a tiff
myBitmap.Save(input, myImageCodecInfo, myEncoderParameters);
Web Forms :: Converting Bitmap To Ehm.bitmap
May 5, 2010I have a colorpicker.png file and track the pixel clicked in codebehind using GetPixel. Works like a charm, but I read that converting to a bitmap on the fly is rather heavy on the server. Therefore I saved my .png file as a .bmp as well, so that a converted file would already exist. However, I don't seem tobe able to just use the bitmap file, but need to create a new bitmap from the bitmap...
My question is: The code below works (I provide it here for those who might need it - simply add the code below to codebehind and this code in your aspx page <asp:ImageButton
ID="cpRubrik"
runat="server"
ImageUrl="~/img/colorpicker.png"
/> ;
also note that the image can be whatever you want - a photo or a screendump of a colorpicker from say Photoshop or VS; and note that it's wise to put everything you need in an updatepanel). Should I write something else in order to get smarter access to the bitmap?
Protected Sub cpRubrik_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles cpRubrik.Click
tbUtseenderub.ForeColor = BytFarg(e.X, e.Y)
End Sub
Protected Function BytFarg(ByVal x As Integer, ByVal y As Integer) As Color
Dim myBitmap As New Bitmap(Server.MapPath("~/img/colorpicker.bmp"))
Dim clr As Color = myBitmap.GetPixel(x, y)
Return clr
End Function

Jun 14, 2010I can do the above by placing the relevant .jpg into the VWD project.
However, I would like to be able to to do this without adding the image file to the project.
e.g. In code, get the image from C:/images/NameOfImage.jpg
The reason I am trying to do this is the website will allow the user to upload as many images as they like. Each one's details will be stored in a database, including details of which location they have uploaded the image to. On retrieval, I will get the location of a specific image from the database, and display it on the page.

I tried setting the value of an imageurl property of an image control within the OnUploadComplete event however it seems the code 1st refreshes the page, runs through the Page_Load event, then finally the OnUploadComplete, so I'm assuming since it's run last, this is why it doesn't display the imageurl.
