POC# ImageButton Picture Resolution
text
Body
copied!<p>I'm trying to make a simple picture thumbnail application. I've searched the web and have found fairly complicated thumbnail apps, to simple ones. I have a good one working, If I could get the ImageButton Resolution looking good. Currently, everything works fine, but the resoultion of the buttons is horrible (i've tried various width/height variations). </p> <p>I simply iterate through an array of button Image's and set their properties. I call ThumbnailSize() to set the width/height of the Imagebutton. </p> <p>The code is kind of sloppy as of right now, but thats besides the point. I want to know if there is a way to keep or increase the ImageButton resolution while taking a picture (800x600+/-) and shrinking it into a Imagebutton.</p> <pre><code>string[] files = null; files = Directory.GetFiles(Server.MapPath("Pictures"), "*.jpg"); ImageButton[] arrIbs = new ImageButton[files.Length]; for (int i = 0; i < files.Length; i++) { arrIbs[i] = new ImageButton(); arrIbs[i].ID = "imgbtn" + Convert.ToString(i); arrIbs[i].ImageUrl = "~/Gallery/Pictures/pic" + i.ToString() + ".jpg"; ThumbNailSize(ref arrIbs[i]); //arrIbs[i].BorderStyle = BorderStyle.Inset; arrIbs[i].AlternateText = System.IO.Path.GetFileName(Convert.ToString(files[i])); arrIbs[i].PostBackUrl = "default.aspx?img=" + "pic" + i.ToString(); pnlThumbs.Controls.Add(arrIbs[i]); } } public ImageButton ThumbNailSize(ref ImageButton imgBtn) { //Create Image with ImageButton path, and determine image size System.Drawing.Image img = System.Drawing.Image.FromFile(Server.MapPath(imgBtn.ImageUrl)); if (img.Height > img.Width) { //Direction is Verticle imgBtn.Height = 140; imgBtn.Width = 90; return imgBtn; } else { //Direction is Horizontal imgBtn.Height = 110; imgBtn.Width = 130; return imgBtn; } } </code></pre>
