What are in memory bit maps?

[SarahBenjamin]

I am new to chart development, and need some help in creating in memory bit maps. Basically I need to create bit maps for a month . Since we have 12 months, I need 12 bit maps, with rows and columns in it.

 

Can someone please help me with it.

Thanks

Please atttach a drawing of what you need. I am not familiar with the term "bit map"

Thanks for responding to my post.

I want to save the chart as a bit map image and then want to use it in the bitmap object. Dont know how to do that. I have code till here

MemoryStream objMemoryStream = new MemoryStream();

OuterChart.Export(ChartFX.WebForms.

FileFormat.Png, objMemoryStream);

Now I want to use it somehow like this

Bitmap bmp = new Bitmap(objMemoryStream....

But I dont know how to grab the image back from the memory stream. I want to use the image of chart for graphics purposes.

Thanks for your help.

Oh I see. I feel stupid now! I didn't realize you meant Bitmap int the System.Drawing context, I thought you meant some kind of strange chart that plots bits in a map.

Here is the code you need:

MemoryStream objMemoryStream = new MemoryStream();

OuterChart.Export(ChartFX.WebForms.

FileFormat.Png, objMemoryStream);

...

// Later 

Bitmap bmp = (Bitmap) Bitmap.FromStream(objMemoryStream);

// Now you have the chart in an Bitmap object.
