Re: Blurry Back Wall Image

Here is the corresponding code: Chart chart = new Chart(); Bar bar; bar = new Bar(chart); bar.FillSampleValues(); chart.Aspect.View3D = false; chart.Walls.Back.Gradient.Visible = false; chart.Walls.Back.Brush.Image = Image.FromFile(@"d:\TEMP\background.bmp"); Bitmap b = new Bitmap(400, 300); Graphic...

Re: Blurry Back Wall Image

I was trying to use your idea in conjunction with Chart.Draw(Graphics g, Rectangle r) method and it almost worked. The image is now sharp but it is not aligned correctly:

The background is drawn in the top-left part of the chart. Compare to the output of Active X version:

Re: Blurry Back Wall Image

Well, I used v2010 and v2011 - it works all the same. I think you're not getting the same result as I did because you're not doing the same thing. On your screen capture you have a control while what I'm talking about here is export to BMP. Could you please try my exact code?

Re: Blurry Back Wall Image

Sure, here is my Active X code that produce correct output. This code is in C# and it invokes TeeChart via interop. ITChart chart = new TChartClass(); ISeries series = chart.Series(chart.AddSeries(ESeriesClass.scBar)); series.FillSampleValues(); chart.Aspect.View3D = false; chart.Walls.Back.Gradient...

Re: Blurry Back Wall Image

Here is another example just to make the issue really obvious. In this attachement:

background.bmp - very small (1x3 pixels) bitmap to appear on the back wall of a chart
Ax.bmp - desired output generated with TeeChart Active X v2010
NET.bmp - incorrect output generated with TeeChart.NET

Thanks!

Re: Blurry Back Wall Image

Sandra, Thank you much for responding! And I'm sorry for not being clear in the first place, I should have provided my code. I use export to BMP : Chart chart = new Chart(); Bar bar; bar = new Bar(chart); bar.FillSampleValues(); chart.Aspect.View3D = false; chart.Walls.Back.Gradient.Visible = false;...

Blurry Back Wall Image

Hello! We're trying to migrate to TeeChart.NET (2012 4.1.2012.05100) from older Active X version (v2010). Active X version used to produce sharp (aliased) background image: ActiveX.png Analogious code re-writen to TeeChart.NET produces blurry (anti-aliased) background image: NET.png To maintain back...
