C # screenshot tool winform,

C # tool winform,

After several days, there were a lot of objects and all of them were messy. Finally, I tried them one by one.

Bitmap

Graphics

FromImage

Pen

Rectangle

DrawRectangle

It was really messy. After several days, I understood the relationship between parameters.

Idea: form1 is the interface, full screen. Form2 is just a region

Form1 code

Int I = 0; int w = Screen. primaryScreen. bounds. width; int h = Screen. primaryScreen. bounds. height; private void button#click (object sender, EventArgs e) {WindowState = FormWindowState. minimized; Thread. sleep (100); I + = 1; Bitmap B = new Bitmap (w, h); Graphics g = Graphics. fromImage (B); g. copyFromScreen (0, 0, 0, new Size (w, h); B. save ("C:/Users/Administrator/Desktop/" + I + ". jpg "); WindowState = FormWindowState. normal; Clipboard. setImage (B); this. cursor = Cursors. default;} private void button3_Click (object sender, EventArgs e) {System. diagnostics. process. start ("C:/Users/Administrator/Desktop"); TopMost = false; this. cursor = Cursors. default;} private void button2_Click (object sender, EventArgs e) {this. hide (); Form2 f2 = new Form2 (); f2.Show ();}

 

Form2 code

 

Int I = 0; Bitmap bit; Bitmap bit2; Bitmap copy; int x; int y; int xx; int yy; Pen pen = new Pen (Color. red, 2); Rectangle rect = new Rectangle (); Graphics g2; private void Form2_Load (object sender, EventArgs e) {I +++; // Opacity = 0.5; windowState = FormWindowState. minimized; FormBorderStyle = FormBorderStyle. none; this. cursor = Cursors. cross; int w = Screen. primaryScreen. bounds. width; int h = Screen. primaryScreen. bounds. height; bit = new Bitmap (w, h); // obtain the desktop graph Graphics g = Graphics. fromImage (bit); // picture g. copyFromScreen (0, 0, 0, 0, new Size (w, h); pictureBox1.Image = bit; bit. save ("C:/Users/Administrator/Desktop/region" + I + ". jpg "); WindowState = FormWindowState. maximized;} private void picturebox#mouseclick (object sender, MouseEventArgs e) {if (e. button = MouseButtons. right) {this. hide (); Form1 f1 = new Form1 (); f1.Show () ;}} private void picturebox#mousedown (object sender, MouseEventArgs e) {x = Math. abs (e. x); y = Math. abs (e. y);} private void pictureBox1_MouseMove (object sender, MouseEventArgs e) {if (e. button = MouseButtons. left) {xx = Math. abs (e. x); yy = Math. abs (e. y); Graphics g = pictureBox1.CreateGraphics (); rect = new Rectangle (x, y, xx-x, yy-y); Refresh (); g. drawRectangle (pen, rect) ;}} private void picturebox#mouseup (object sender, MouseEventArgs e) {try {copy = (Bitmap) bit. clone (); bit2 = new Bitmap (rect. width, rect. height); g2 = Graphics. fromImage (bit2); g2.DrawImage (copy, new Rectangle (0, 0, rect. width, rect. height), rect, GraphicsUnit. pixel); pictureBox1.Image = bit2; bit2.Save ("C:/Users/Administrator/Desktop/region" + I + ". jpg "); Clipboard. setImage (bit2 );}
