Background code
Description
1. Add pictures and text can not coexist is that you can only use a
2. Add the picture when you have to ensure that you are added watermark picture 3.png in (you can change the other, the program will also change)
Must have this folder that holds the picture, uploadfile (can change oneself other, the procedure also wants to change)
3. To change the text, the position of the picture must be changed in the program.
Program code
public void Uploadbtn_click (Object Sender,eventargs e) {
String filename;
String filename1;
String[] filename2;
int q;
Filename=uploadfile.postedfile.filename;
Filename2=filename. Split (new char[] {' \ \} ');
Q=filename2. GetUpperBound (0);
FILENAME1=FILENAME2[Q];
Dis. text= "Upload filename:" +filename1+ "<br>";
UploadFile.PostedFile.SaveAs (Server.MapPath (filename1));
Imageeditor.visible = true;
Dis. text+= "File size:" +uploadfile.postedfile.contentlength+ "number of bytes";
image1.src=filename1;
}
void Updatebtn_click (Object sender, EventArgs e) {
String filename1;
FILENAME1=IMAGE1.SRC;
Add text watermark, note that the code here and the following image watermark code can not coexist
System.Drawing.Image Image = System.Drawing.Image.FromFile (Server.MapPath (filename1));
System.Drawing.Image newimage = new Bitmap (Image. Width,image. HEIGHT,PIXELFORMAT.FORMAT32BPPRGB);
Graphics g = graphics.fromimage (newimage);
G.drawimage (image,0,0,image. Width,image. Height);
Font f= new Font (FontType.SelectedItem.Text, Int32.Parse (FontSize.SelectedItem.Text));
Brush B = new SolidBrush (color.antiquewhite);
g.DrawString (Caption.text, F, b, 100, 140);
G.dispose ();
Add Image Watermark
System.Drawing.Image Image = System.Drawing.Image.FromFile (Server.MapPath (filename1));//Original
System.Drawing.Image newimage = System.Drawing.Image.FromFile (Server.MapPath ("3.png"));//This object is an added watermark
Graphics g = graphics.fromimage (image);
G.drawimage (NewImage, new Rectangle) (image. Width-newimage.width, image. Height-newimage.height, NewImage. Width, NewImage. Height), 0, 0, NewImage. Width, NewImage. Height, GraphicsUnit.Pixel);
G.dispose ();
Add text watermark
System.Drawing.Image thumbimage = newimage. Getthumbnailimage (image. Width,image. Height,null,new IntPtr ());
Image. Dispose ();
Thumbimage.save (Server.MapPath (filename1), imageformat.jpeg);
Add Image Watermark
Image. Save (Server.MapPath ("uploadfile/" +filename1));
IMAGE1.SRC = filename1;
Caption.text= "";
}
