4. MEMBACA DAN MENYIMPAN FILE GAMBAR A. LISTING PROGRAM

//OPEN FILE private void button1_Click(object sender, EventArgs e) { DialogResult d = openFileDialog1.ShowDialog(); if (d == DialogResult.OK) { File = Image.FromFile(openFileDialog1.FileName); pictureBox1.Image = File; } }

//SAVE FILE private void button2_Click(object sender, EventArgs e) { DialogResult d = saveFileDialog1.ShowDialog(); if (d == DialogResult.OK) {

File.Save(saveFileDialog1.FileName, ImageFormat.Jpeg); } }

B. PERTANYAAN

- Pada komponen PictureBox, terdapat segitiga kecil di

bagian kanan atas yang digunakan untuk mengubah

size-mode. Jelaskan apa perbedaan masing-masing size-

mode:

a. Normal -> gambar akan ditampilkan sebagian saja yaitu diambil dari pojok kiri atas dan memiliki ukuran sama dengan luas picture box.

b. StrechtImage -> gambar akan ditampilkan menyesuaikan dengan luas picturebox yang telah dibuat.

c. AutoSize -> gambar akan ditampilkan sesuai dengan ukuran gambar yang sebenarnya, tidak menyesuaikan dengan luas picturebox.

d. CenterImage -> gambar akan ditampilkan sebagian saja yaitu diambil dari tengah gambar dan memiliki ukuran sama dengan luas picture box

e. Zoom -> gambar aka ditampilakan sesuai dengan luas picturebox. Namun berukuran lebih besar dari mode StrechImage.

- Jelaskan apa fungsi dari perintah pictureBox1.Image = File;

-> berfungsi untuk menyatakan bahwa gambar pada picturebox1 berasal dari file yang akan di load.

5. MEMBACA DATA PROGRAM A. LISTING PROGRAM

//LOAD GAMBAR private void Form1_Load(object sender, EventArgs e) {

}

private void button1_Click(object sender, EventArgs e) { DialogResult d = openFileDialog1.ShowDialog(); if (d == DialogResult.OK) { objBitmap = new Bitmap(openFileDialog1.FileName); pictureBox1.Image = objBitmap; } }

//COPY GAMBAR private void button2_Click(object sender, EventArgs e) { objBitmap1 = new Bitmap(objBitmap); for (int x = 0; x < objBitmap.Width; x++) for (int y = 0; y < objBitmap.Height; y++) { Color w = objBitmap.GetPixel(x, y); objBitmap1.SetPixel(x, y, w); } pictureBox2.Image = objBitmap1; }

//FLIP HORIZONTAL private void button3_Click(object sender, EventArgs e) { objBitmap1 = new Bitmap(objBitmap); for (int x = 0; x < objBitmap.Width; x++) for (int y = 0; y < objBitmap.Height; y++) { Color w = objBitmap.GetPixel(x, y); objBitmap1.SetPixel(objBitmap.Width - 1 - x, y, w); } pictureBox2.Image = objBitmap1; }

//FLIP VERTICAL private void button4_Click(object sender, EventArgs e) { objBitmap1 = new Bitmap(objBitmap); for (int x = 0; x < objBitmap.Width; x++) for (int y = 0; y < objBitmap.Height; y++) { Color w = objBitmap.GetPixel(x, y); objBitmap1.SetPixel(x, objBitmap.Height - 1 - y, w); } pictureBox2.Image = objBitmap1;

}
