drawn an rectangle on the image using picture box.
quires
1. when tried to zoom image the drawn rectangles needs to be placed on the drawn area.
2. Also draw another rectangle (in zoomed mode).
3. when i zommed out the rectangle needs to resized.
How can i achieve this.
I achieved this by using graphics.drawrectangle but i don't want to draw rectangle on the image because it's stay permanently on the image.
Please help on this......
public void ZoomIn()
{
if (sz1.Width >= 800 * 6)
MessageBox.Show("Max ZoomIn");
else
{
sz1.Width += 100;
sz1.Height += 100;
pictureBox1.Size = sz1;
pictureBox1.Invalidate();
}
}
private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
if (mybitmap == null)
{
mybitmap = new Bitmap(pictureBox1.Image.Width, pictureBox1.Image.Height);
mybitmap.SetResolution(300, 300);
}
rect = new Rectangle(e.X, e.Y, 0, 0);
pictureBox1.Invalidate();
}
private void pictureBox1_Paint(object sender, PaintEventArgs e)
{
if (mybitmap == null)
{
return;
}
using (Pen pen = new Pen(Color.Green, 2))
{
foreach (Rectangle r in rectangles)
{
e.Graphics.DrawRectangle(pen, r);
e.Graphics.DrawString(lab[c].ToString(), new Font(lab[c].ToString(), 8F), new SolidBrush(label1.ForeColor), r);
}
}
}

You can't seriously expect anyone to wade through all of this code. Focus in on a specific issue and show a code fragment: if anyone wants to help and wants to see more they'll ask but you'll not get an answer whilst your question remains like this.

It looks like you are not resizing the rectangle.
Just racking up the postings

just tried to resize the rectangle as below (for x and y ). but this co-ordinate varies from point to point.
public void ZoomIn()
{
if (sz1.Width >= 800 * 6)
MessageBox.Show("Max ZoomIn");
else
{
sz1.Width += 100;
sz1.Height += 100;
pictureBox1.Size = sz1;
c = 0;
rect1 = new Rectangle(rectangles[c].X+((pictureBox1.Width/rectangles[c].Height)+(pictureBox1.Width/100)),rectangles[c].Y+((pictureBox1.Height/rectangles[c].Width)), rectangles[c].Width, rectangles[c].Height);
rectangles.RemoveAt(c);
rectangles.Insert(c, rect1);
rect = new Rectangle(0, 0, 0, 0);
}
}
How to resize it...

ratio = Convert.ToDouble(sz1.Width) / Convert.ToDouble(pictureBox1.Width);
rect1.X = Convert.ToInt16((rectangles[c].X) * ratio);
rect1.Y = Convert.ToInt16((rectangles[c].Y * ratio));
rect1.Width = Convert.ToInt16(rectangles[c].Width * ratio);
rect1.Height = Convert.ToInt16(rectangles[c].Height * ratio);
rectangles.RemoveAt(c);
rectangles.Insert(c, rect1);
pictureBox1.Size = sz1;

Below is sample code from one of my recent apps. I used this pattern a lot when designing searchable objects. I know that by appearances, there will be more than two method calls involved.
However, I've read that the C# compiler inlines short blocks of code.
Will the "Contained" method be inlined at compile time?
public bool Contains(BindingPathNodeType nodeType)
{
return IndexOf(nodeType) != -1;
}
public int IndexOf(BindingPathNodeType nodeType)
{
int intCount = parsedPathNodes.Length;
for (int i = 0; i < intCount; i++)
if (parsedPathNodes[i].NodeType == nodeType)
return i;
return -1;
}
The mind is like a parachute. It doesn’t work unless it’s open.

|
|
|
|
# DEFINE Contains(x) (IndexOf(x) != -1)
|
|
|
|
|
What is this? Some kind of shorthand?

Yeah, kinda.

If BindingPathNodeType is a reference type then there seems to be nothing that prevents inlining.
But, as has been said, you still don't know for sure whether it will be inlined.
What has not been said though is that it also depends on whether you NGEN, and whether it's 64bit, and 64bit NGEN is completely different from anything else, IIRC not even created by the same team (instead of being developed by the CLR team, it was developed by the Visual C++ team)
'Contains' is not a leaf method, while I have read nothing about non-leaf methods not being inlined, in other compilers inlining is often done on leaf methods first.

Thanks for the heads up. I don't NGEN any of my code so I'm probably in trouble.
I hate having to enter the same code block twice because:
1. It looks dirtier.
2. More lines to (possibly) debug.

I don't think I can use ClickOnce (or can I?) because it's a plugin....

If you architect the application correctly with plugin modules, or MEF, it can be used to deploy the modules.

This should be posted in the Lounge as it's not a C# question.

Most would, but I get your point.
It was more of a statement/comment than a question IMO, if meant as a question then the .NET Framework forum would have been the correct place.
I didn't mean it personally hence not downvoting your post
[Edit: unlike others I see )

Maybe they were thinking "this would be a nice way to get more support for 64bit" or maybe "this would make it easier to support new instruction sets in old programs without recompiling them" but if they were thinking that they should think again, it's true of course but they are still using the FP stack instead of SSE registers.
