Question

User-1103495211 posted

I try to write some text in a image.
I want it in a rectange because i  want to set the align to center in a part of the image.
It works but the quality of the written text is so very bad, it isn't even white ...

You can see where i write the text, the quality of the image is bad, you can see that on the place in the real image...
What can i do to solve that? And i whant white fonts not light blue fonts...

My code is :

                                dbImage = ImageControl.ImageMerger.AddPNG(dbImage, ConfigurationManager.AppSettings["localPath"].ToString() +  @"images\rectangleRound.png", ImageControl.PositionVertical.Top, ImageControl.PositionHorizontal.Left, 260, 190, paddingleft, paddingtop);
                                if (Request["prijsex"] != null)
                                {
                                    //Add Text
                                    Bitmap target = new Bitmap(260, 190, PixelFormat.Format32bppRgb);
                                    using (Graphics objGraphics = Graphics.FromImage(target))
                                    {
                                        objGraphics.DrawImage(dbImage, 0, 0, 260, 190);
                                        // Set anti-aliasing for text to make it better looking
                                        objGraphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias;                                        
                                        
                                        // Configure font to use for text
                                        System.Drawing.Font objFont = new Font("Arial", 10, FontStyle.Bold);                                       
                                        //Write out the text                                   
                                        string hexCol = "#FFFFFF";
                                        RectangleF drawRect = new RectangleF(186, 134, 70, 20);
                                        RectangleF drawRectLeft = new RectangleF(146, 134, 70, 20);       
                                        
                                        SolidBrush sb = new SolidBrush(System.Drawing.ColorTranslator.FromHtml(hexCol));
                                        SolidBrush sred = new SolidBrush(Color.Red);
                                        StringFormat SF = new StringFormat();
                                        SF.Alignment = StringAlignment.Center;                                        

                                        objGraphics.DrawString("€" + Request["prijsex"].ToString(), objFont, sb, drawRect, SF);
                                        objGraphics.DrawString("€" + Request["prijsex"].ToString(), objFont, sb, drawRectLeft, SF);
                                        //Save
                                        objGraphics.Save();
                                    }
                                    dbImage = (System.Drawing.Image)target;

target.SetResolution(original.HorizontalResolution, original.VerticalResolution);
