Dominik posted over 12 years ago

Hello Guys ...

I've 12 Charts on one Page. Now i'll export these on PDF! But the DPI of the Charts are so bad, and ive to set it on my own .. works great! But... look at the picture .. my Problem are the Fonts of the Chart?!

Here is my Code:

chart.PreRender += new EventHandler((o, args) =>

{

FileStream fileStream = new FileStream(Server.MapPath("~/ChartImages/Chart_" + ((UltraChart)o).Attributes["index"] + "_druck.png"), FileMode.Create, FileAccess.ReadWrite);

((UltraChart)o).SaveTo(fileStream, System.Drawing.Imaging.ImageFormat.Png, new Size(1600, 1200), new SizeF(300,300));

fileStream.Close();

});

Question is now .. waht property should i set or change to make the area of the text inside the Chart bigger?!

Thanks for solutions...

Hi Inoir,

I have received word from development regarding this issue. It seems that this is the behavior of GDI+ by design. The chart itself does not do any special handling of alternate resolutions, it simply passes the parameters when saving the image. The same behavior may be observed using the following code:

Code Snippet

Bitmap bmp1 = new Bitmap(250, 250);

bmp1.SetResolution(300f, 300f);

Graphics graphics1 = Graphics.FromImage(bmp1);

graphics1.DrawString("hello", new Font("Arial", 12f), Brushes.Black, new Point(100, 100));

bmp1.Save(HttpContext.Current.Server.MapPath("test1.png"));

Bitmap bmp2 = new Bitmap(250, 250);

bmp1.SetResolution(30f, 30f);

Graphics graphics2 = Graphics.FromImage(bmp2);

graphics2.DrawString("hello", new Font("Arial", 150f), Brushes.Black, new Point(100, 100));

bmp2.Save(HttpContext.Current.Server.MapPath("test2.png"));

Feel free to contact me if you have any questions.
