    <p>I am having a problem with converting the image from PNG to JPG. From jpg to jpg is very good but from PNG to jpg is having a pixelated problem. I've already implemented the compression method into this code but it still couldn't produce a high quality image.</p> <p>Any ideas guys?</p> <pre><code>using System; using System.Collections.Generic; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Drawing.Imaging; using System.Drawing; using System.IO; using System.Drawing.Drawing2D; public partial class _Default : System.Web.UI.Page { private ImageCodecInfo GetEncoder(ImageFormat format) { ImageCodecInfo[] codecs = ImageCodecInfo.GetImageDecoders(); foreach (ImageCodecInfo codec in codecs) { if (codec.FormatID == format.Guid) { return codec; } } return null; } protected void Page_Load(object sender, EventArgs e) { Response.ContentType = "image/JPEG";//convert toJPEG for web usage // Get a bitmap. Bitmap bmp1 = new Bitmap(@"E:\websites\LogoMaster\LogoID4.png"); ImageCodecInfo jgpEncoder = GetEncoder(ImageFormat.Jpeg); // Create an Encoder object based on the GUID // for the Quality parameter category. System.Drawing.Imaging.Encoder myEncoder =System.Drawing.Imaging.Encoder.Quality; // Create an EncoderParameters object. // An EncoderParameters object has an array of EncoderParameter // objects. In this case, there is only one // EncoderParameter object in the array. EncoderParameters myEncoderParameters = new EncoderParameters(1); EncoderParameter myEncoderParameter = new EncoderParameter(myEncoder, 100L);//SET to the highest quality myEncoderParameters.Param[0] = myEncoderParameter; // bmp1.Save(@"E:\websites\LogoMaster\TestPhotoQualityHundredp.jpg", jgpEncoder, myEncoderParameters); bmp1.Save(Response.OutputStream, jgpEncoder, myEncoderParameters); bmp1.Dispose(); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
