Hello, I wrote this small function that reads an image file and copies parts of a that image into picture boxes which are added to a panel. This function works the way I wanted it to work for MOST pictures, however, for some large images, it doesn't. Sometimes the image inside the picture boxes is displayed like half the size it should be.
I wonder if someone could tell me why that is.
Thanks in advance
This is what I have:
Expand|Select|Wrap|Line Numbers
- voidreadpic()
- {
- openFileDialog1.ShowDialog();
- Imageimg=Image.FromFile(openFileDialog1.FileName.ToString());
- Bitmapbmp=(Bitmap)img;
- PictureBox[]px;
- intcounter=0;
- px=newPictureBox[(img.Size.Width/64)];
- for(intp=0;p<(img.Size.Height/64);p++)
- for(inti=0;i<(img.Size.Width/64);i++)
- {
- {
- Bitmapbmp2=newBitmap(64,64);
- Rectanglerect=newRectangle();
- rect.Height=64;
- rect.Width=64;
- rect.X=0+i*64;
- rect.Y=0+p*64;
- bmp2=CopyBitmap(bmp,rect);
- px[i]=newPictureBox();
- px[i].Name=counter.ToString();
- px[i].Tag=px[i].Name;
- px[i].BorderStyle=BorderStyle.Fixed3D;
- px[i].Height=64;
- px[i].Width=64;
- px[i].Image=bmp2;
- px[i].Left=i*64;
- px[i].Location=newPoint(1+i*64,1+p*64);
- px[i].Click+=newEventHandler(Form1_Click);
- panel1.Controls.Add(px[i]);
- counter++;
- }
- }
- }

Why don't you just use the .GetThumbnail() function to do the resizing for you?
Or is that contained with your CopyBitmap function?

Does this run just they way you entered it here?
I have my doubts about lines 12-15...
12. for loop declaration
13. for loop declaration
14. {
15. {
Shouldn't this be...
12. for loop
13. {
14. for loop
15. {
I'm just wondering if the way posted works, is legal and does something different or interesting from the 'normal' or 'other' way to do nested loops that I suggested.

I changed the position of the braces but it doesn't have an effect.
