Problem with DrawString under Windows 7

Question

I need to convert text to image using specified fonts size etc. Looks like everything is ok when using standard DrawString method but when I'm trying to do it under Windows 7 I have my picture blurred. this is a screenshot from Windows XP / Windows 2008 server http://testmyblog.ho.ua/pictures/xp.png and this is from Windows 7 http://testmyblog.ho.ua/pictures/7.png Also I tried to play with System.Drawing.Imaging.Encoder.Quality; but even with max value of EncoderParameter blur effect doesn't disappear. I have no idea where is the problem hope that you will be able to help.

Friend Here is How you can Draw clean String protected override void OnPaint( PaintEventArgs e) { Graphics g = e.Graphics; Brush b = new SolidBrush ( Color .Black); //this is to Draw Antialiaced Clean String g.TextRenderingHint = System.Drawing.Text. TextRenderingHint .AntiAlias; g.DrawString( Kirtan  new Font ( FontFamily .GenericSansSerif 50) b new Point (200 50)); }

Hi you can try this code for Convert text to image in c# using System.Drawing namespace. Here we create a bitmap image and use its Graphics property to convert text passed to image and place the image in a picture box. private void TextToImage ( ) { Color BackColor = Color. White ; String FontName = Times New Roman ; int FontSize = 25 ; int Height = 50 ; int Width = 300 ; span style = color: rgb(56 118 29); > //creating bitmap image span style = color: rgb(0 0 0); > Bitmap span > span > bitmap = new Bitmap ( Width Height ) ; span style = color: rgb(56 118 29); > //FromImage method creates a new Graphics from the specified Image. Graphics graphics = Graphics. FromImage ( bitmap ) ; Color color = Color. Gray ; Font font = new Font ( FontName FontSize ) ; SolidBrush BrushBackColor = new SolidBrush ( BackColor ) ; Pen BorderPen = new Pen ( color ) ; Rectangle displayRectangle = new Rectangle ( new Point ( 0  0 )  new Size ( Width - 1  Height - 1 ) ) ; span style = color: rgb(56 118 29); > //Drawing a rectangle and filling the background as white span style = color: rgb(0 0 0); > graphics span > span > . FillRectangle ( BrushBackColor displayRectangle ) ; graphics. DrawRectangle ( BorderPen displayRectangle ) ; span style = color: rgb(56 118 29); > //giving the font and color to the string passed graphics. DrawString ( txtEnter. Text fontBrushes. Red  0  0 ) ; pictureBox1. Image = bitmap ; }

Friend The Drawing you are Talking about is Vector Drawing. basically Antialiase Feature can make Drawing smoother than it looks so when you zoom your image in windows form with button actually yo need to redraw it so use fills that image quality is not reduced after zooming :)

Kirtan thanks for your answer. I tried this solution but it only removes colored pixels from picture blur effect doesn't disappear. The important point that I need to use font size from 5 to 20. Here is a picture with size 7: http://img214.imageshack.us/img214/4670/fromfile.png I tried to draw text in the pictureBox (probably the problem was in exporting to the file or something) but the picture looks the same as in file. http://img214.imageshack.us/img214/9834/fromform.png
