Question

Hello,
I want to develop one online application, which user enter any word (fname,lname) itself on images.
and also that image can be download his/her computers.
e.g
Like online form application.
user fill up online form it self and then his/her download that form.
But,I want fill up the form on image.
I have develop small application.
it's fill the form on one page and then click button then redirect all value to another page on images.
here it's working. but, when I try to export all details with image/pdf so, it's not working, meant it's not download images.
code for export pdf file.
Response.ContentType = "application/pdf";         Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");         Response.Cache.SetCacheability(HttpCacheability.NoCache);         StringWriter sw = new StringWriter();         HtmlTextWriter hw = new HtmlTextWriter(sw);         this.Page.RenderControl(hw);         StringReader sr = new StringReader(sw.ToString());         Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);         HTMLWorker htmlparser = new HTMLWorker(pdfDoc);         PdfWriter.GetInstance(pdfDoc, Response.OutputStream);         pdfDoc.Open();         htmlparser.Parse(sr);
pdfDoc.Close();         Response.Write(pdfDoc);         Response.End();

thanks for sharing! I use an imaging sdk which can create watermark found on the internet . Install it and it becomes a selectable processing option.Then you can create watermark in your image in any program at all, including Adobe Acrobat . Just open the images, select watermarkl,and follow the setps given in the sdk, the task will be finished in several seconds. if you haven´t found a good choice , you can have a try. best wishes.
