Dear Richard ..thanks for ur interest man..but finally i wrote acode that can save the file at C Drive as atext but while opening the program can read the data from text..but it cant display it ..this valid while drawing LINES ONLY..my problem is:
--------> how can i make the program display the file ( draw the lines..) & how can i do that for ellipse & polygons.
this apart of my code :

Hello...
i need to split the forms to two screens show..
like one window wolla start at the main screen and any given time other windows pop up at second screen...
Thanks...

What language are you using ? .NET languages have a Screen.AllScreens enum that gives you the bounds of all your screens, so it's trivial to position windows in them.

The eraser is just drawing a thick line in the background color. Pretty easy stuff. Which bit are you stuck on ?

Hi, we're a couple of students on our internship, and we're kinda stuck in the project we're doing. I'll first try to explain what it is we are expected to make.
You have to imagine a white empty 2D paper which is virtually unlimited in size. An admin can place a question on this paper, users can then reply on the active question. The admin can also zoom in and zoom out and drag the paper around and post new questions. So we have to work with an environment that contains a fair amount of questions linked to answers. Every question can be differently scaled, so this means that you have to zoom in more on some questions than others.
Basic functionality would have to be panning the paper, by that I mean hold mouse down and dragging it to another position, thus moving all objects on the paper in that direction.
We've tried this with the following code, however the performance was really bad.
void Window_MouseUp(object sender, System.Windows.Input.MouseButtonEventArgs e)<br />
{<br />
if (mbMouseDown)<br />
{<br />
Point bNew = e.GetPosition(Window);<br />
foreach (UIElement oObject in LayoutRoot.Children)<br />
{<br />
Canvas.SetTop(oObject, bNew.X - mpBegin.X);<br />
Canvas.SetLeft(oObject, bNew.Y - mpBegin.Y);<br />
}<br />
}<br />
mbMouseDown = false;<br />
}<br />
<br />
void LayoutRoot_MouseMove(object sender, System.Windows.Input.MouseEventArgs e)<br />
{<br />
if (mbMouseDown)<br />
{<br />
Point bNew = e.GetPosition(Window);<br />
foreach (UIElement oObject in LayoutRoot.Children)<br />
{<br />
Canvas.SetTop(oObject, bNew.X - mpBegin.X);<br />
Canvas.SetLeft(oObject, bNew.Y - mpBegin.Y);<br />
}<br />
}<br />
}<br />
<br />
void LayoutRoot_MouseDown(object sender, System.Windows.Input.MouseButtonEventArgs e)<br />
{<br />
mbMouseDown = true;<br />
mpBegin = e.GetPosition(Window);<br />
}
With the zooming we tried the scaling functionality of wpf.
private void Window_MouseWheel(object sender, MouseWheelEventArgs e)<br />
<br />
{<br />
<br />
if (e.Delta > 0)<br />
<br />
{<br />
<br />
mpScaleSize = new Point((mpScaleSize.X - 0.05), (mpScaleSize.Y - 0.05));<br />
<br />
grdCanvas.LayoutTransform = new ScaleTransform(mpScaleSize.X, mpScaleSize.Y);<br />
<br />
zoomX.Content = mpScaleSize.X.ToString();<br />
<br />
zoomY.Content = mpScaleSize.Y.ToString();<br />
<br />
}<br />
<br />
else<br />
<br />
{<br />
<br />
mpScaleSize = new Point((mpScaleSize.X + 0.05), (mpScaleSize.Y + 0.05));<br />
<br />
grdCanvas.LayoutTransform = new ScaleTransform(mpScaleSize.X, mpScaleSize.Y);<br />
<br />
zoomX.Content = mpScaleSize.X.ToString();<br />
<br />
zoomY.Content = mpScaleSize.Y.ToString();<br />
<br />
}<br />
<br />
}
This again wasn't going smoothly.
(My laptop is a IBM Thinkpad r50p, 1,7Ghrz Centrino, 1gig RAM, maybe it's just not fast enough?)
Anyway , I've posted this same question on the msdn forums. One person with little experience with the subject suggested me that I should try to work with visualBrushes and use it as some kind of view. I've been playing around with the VisualBrushes for a while now.
I've managed to get controls from code onto the VisualBrush(which is on a rectangle in the center of my app), however working with VisualBrush as some kind of view isn't working for me.What I "discovered"is that working with the viewbox property of the visualbrush might be the solution, but I can't seem to get it to work.
To my understanding the viewbox is a rectangle with it's x & y as panning values, and it's with & height as crop/stretch values (zoom).
Anyone with some experience in the area, I would really appreciate the help.
Thanks,
Tobias

Hi
I want to do some limited filters on an image (like converting RGB to MonoColor)
I do this now by to inner loop on image scales and use GetPixel method on this but it's real Slow.
Who can help me to do that with realtime speed (like Adobe Photoshop).

After Mark Salsbery showed me the wonders of DirectShow Editing Services (Thanks Mark!) i was able to take a bunch of mpegs, put them on after the other and add background music and save the output to an avi file.
One problem. I am having problems Compressing it. The output file is huge since i am not compressing it.
The following example from the DirectShow documentation shows this:
long NumGroups;
pTimeline->GetGroupCount(&NumGroups);
// Loop through the groups and get the output pins.
for (i = 0; i < NumGroups; i++)
{
IPin *pPin;
if (pRender->GetGroupOutputPin(i, &pPin) == S_OK)
{
IBaseFilter *pCompressor;
// Create a compressor filter. (Not shown.)
// Set compression parameters. (Not shown.)
// Connect the pin.
pBuilder->RenderStream(NULL, NULL, pPin, pCompressor, pMux);
pCompressor->Release();
pPin->Release();
}
}
They do not show how to create a compression filter. So meanwhile my compressor is NULL, this is why my output is so huge.
Anyone have any idea how to create a compressor filter? Show me some code xample?
Thanks,
Michael

I had no idea that stuff actually worked!!
The only compressor that comes with directshow is for writing ASF (.wma,.wmv, etc) files.
I believe MPEG-4 is built-in to that but other flavors of MPEG are license-protected.
If you can live with an ASF file, a method is shown here (note you'll need the Windows Media
Format SDK to use the WM ASF Writer Filter, which is a mux.writer combo filter):
Writing a Windows Media File in DES[^]
If you need to output MPEG-1, and you have a MPEG-1 mux filter, you should be able to add it to the graph before the file writer. I'm pretty sure we discussed this before but I'm not sure
exactly how it works since I've never used any third-party filters. I would expect a mux filter
to have multiple input pins and one compressed format output pin.
Hope that helps a little!

I forgot to ask - What filter(s) are you using to write the AVI file??

Hey Mark, Nice to talk to you again....
I don't know how much experience you have with DirectShow Editing Services.
The truth is i don't really know what filters i am currently using.
I guess it automatically uses the default filters since i did not manually order it to use any specific filters.
I have an open source mpeg-2 decoder and an open source ac3 filter (for the sound).
I am guessing that underneath it uses the mpeg-2 splitter and both of these decoders for video and sound.
For the mux, i saw that i have an avi muxer through the graphedit tool - didn't this come with windows?
1. Is is the avi muxer i have a third party tool?
2. Is there a way for me to definitely know which filters DES is using?
3. Do asf decoders come by default on windows systems?
4. The reason you think we already had this conversation was because in the past i wanted to ouput to mpeg-2, but there were no built-in muxers and now i have this avi-muxer "qcap.dll" if i recall correctly.
5. There is something called smart-rendering in DirectShow Editing Services have you had any experience with it?(ISmartRenderEngine).
6. In my other post i explained that my output file is huge because i am not compressing. I do not know how to create a compressor filter, not with the basicengine and not with the smartengine.
Thanks,
Michael

I have no problem sending you or posting you my entire class. It's not that much, that way i can show you the place where i am supposed ot have a compressor filter and instead i place NULL because i do not know how ot create one...
Thnx

The AVI muxer comes with DirectShow.
I have lots of experience with Windows Media Format (ASF) - that's what I use in my software.
The Windows Media Format compression works well for my needs, including realtime streaming.
I haven't used the AVI muxer but I know it is configurable for various compression settings.
I see it uses the Video Compression Manager but I'm not sure what types of compressors are
included with Windows - I'm looking into that.
The Windows Media stuff comes with windows starting in XP. The SDK comes with (or you can
download) a redistributable install package for previous Windows versions. Pretty much the same
deal as DirectX installation (but alot smaller).
I'll definitely take a look at your code - I'll send an email you can reply to.

I have succesfully created compression filters also for my audio and also for my video.
The problem is that i do not know which codec to use now.
The Divx codec that i have does not allow me to control the frame rate or quality because it does not support this.
The codecs that do allow me to have control give me bad quality\file size ratio.
What codec can i use will allow me to control the frame rate and quality for Avi compression and have a reasonable size for the output file.
Reminder: i am compressing from mpeg-2 to avi.
Thanks,
Michael

More information on why i cannot use the Divx codec:
When using the IAMVideoCompression:GetInfo on the codec it returns 0 for capabilities. Meaning that it does support controlling the codec through this interface and I cannot control the frame rate, quality etc....
Is there a way around this? or another codec that does allow me to control this?
Thank you,
Michael

Hi,
I have a number of still images containing concentric circles and I would like to be able to detect the centre point of the circles. Are there any algorithms out there that would allow me to do this?
Cheers,
Tony
