this.MinimizeBox = false;
tsize.MaxLength = 3;
tsize.Enabled = false;
}
void ubahsize()
{
if (tsize.Text != "")
{
int persen = Convert.ToInt32(tsize.Text);
int tinggi = (persen * Convert.ToInt32(ltinggi.Text)) / 100;
int lebar = (persen * Convert.ToInt32(llebar.Text)) / 100;
ltinggi.Text = Convert.ToString(tinggi);
llebar.Text = Convert.ToString(lebar);
}
}
void simpangambar()
{
int tinggi = Convert.ToInt32(ltinggi.Text);
int lebar = Convert.ToInt32(llebar.Text);
Bitmap ukuranbaru = new Bitmap(lebar, tinggi,
System.Drawing.Imaging.PixelFormat.Format24bppRgb);
Graphics gbr = Graphics.FromImage(ukuranbaru);

System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
gbr.PixelOffsetMode =
System.Drawing.Drawing2D.PixelOffsetMode.HighSpeed;
Rectangle rect = new Rectangle(0, 0, lebar, tinggi);
gbr.DrawImage(gambar, rect);
SaveFileDialog simpan = new SaveFileDialog();
simpan.Filter = "Jpeg Format|*.Jpg";
simpan.RestoreDirectory = true;
if (simpan.ShowDialog() != DialogResult.Cancel)
{
ukuranbaru.Save(simpan.FileName);
ukuranbaru.Dispose();
MessageBox.Show("Gambar Berhasil Disimpan", "Info");
}
}
void bukagambar()
{
OpenFileDialog bukagambar = new OpenFileDialog();
if (bukagambar.ShowDialog() == DialogResult.OK)
{
this.gambar = Image.FromFile(bukagambar.FileName);
picture.SizeMode = PictureBoxSizeMode.StretchImage;
picture.ImageLocation = bukagambar.FileName;
ltinggi.Text = gambar.Height.ToString();
llebar.Text = gambar.Width.ToString();
tsize.Enabled = true;
tsize.Clear();
}
}
private void tsize_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
ubahsize();
}
}
private void Bbuka_Click_1(object sender, EventArgs e)
{
bukagambar();
}
private void bsimpan_Click_1(object sender, EventArgs e)
{
simpangambar();
}
}
}
*Jika tidak bisa Buka / Simpan gambar, hapus codingan button diatas lalu kembali ke form design anda lalu klik 2 kali pada button lalu masukan kembali codingannya.
- Berikut gambar setelah program dijalakan.
