すいませんでした。正直に言います。アイコンエディタを作ってみたくて以下のようなクラスを作りました。
public enum SIZETYPE:int
{
SIZE16 = 16,
SIZE32 = 32,
SIZE48 = 48,
}
public delegate void PictureBoxImageChange(Canvas c, EventImageArgs pe);
public class Canvas:PictureBox
{
public event PictureBoxImageChange PictureBoxImageChange;
public Canvas()
{
if (Sizetype == SIZETYPE.SIZE16)
{
this.Width = 10 * (int)sizeType;
this.Height = 10 * (int)sizeType;
this.Location = new Point(0, 0);
this.Size = new Size(160, 160);
this.SizeMode = PictureBoxSizeMode.AutoSize;
panel1.Size = new Size(160, 160);
panel1.AutoScroll = true;
panel1.Margin = new System.Windows.Forms.Padding(0);
panel1.Controls.Add(this);
Init16();
}
}
private Panel panel1 = new Panel();
public const int STEP = 10;
int size =16;
public int DrawSize
{
get { return size; }
set { size = value; }
}
RectangleF[] Rects;
SIZETYPE sizeType = SIZETYPE.SIZE16;
public SIZETYPE Sizetype
{
set { sizeType = value; }
get { return sizeType; }
}
//PictureBox pictBox = new PictureBox();
float step = STEP;
public float Step
{
set { step = value; }
get { return step; }
}
float WIDTH = 160f;
public float FWidth
{
set { WIDTH = value; }
get { return WIDTH; }
}
float HEIGHT = 160f;
public float FHeight
{
set { HEIGHT = value; }
get { return HEIGHT; }
}
float zoom = 1.0f;
public float Zoom
{
set { zoom = value; }
get { return zoom; }
}
public void Init16()
{
float w = (float)(10 * (int)sizeType);
float h = (float)(10 * (int)sizeType);
w *= Zoom;
h *= Zoom;
this.FWidth = w;
this.FHeight = h;
this.Size = new Size(((int)this.FWidth), ((int)this.FHeight));
float step = (float)STEP;
step *= Zoom;
this.Step = step;
Rects = new RectangleF[(int)sizeType * (int)sizeType];
Graphics g = Graphics.FromImage((this.Image = new Bitmap(this.Width, this.Height)));
int l = 0;
for (float i = 0; i < this.FWidth; i += Step)
{
for (float j = 0; j < this.FHeight; j += Step)
{
Rects[l++] = new RectangleF(j, i, Step, Step);
}
}
Pen pen = new Pen(Color.FromArgb(255, 0, 0, 255), 1);
g.DrawRectangles(pen,Rects);
this.BorderStyle = BorderStyle.None;
Rectangle borderRectangle = this.ClientRectangle;
borderRectangle.Inflate(0, 0);
ControlPaint.DrawBorder3D(g, borderRectangle,
Border3DStyle.Raised);
this.Refresh();
g.Dispose();
pen.Dispose();
}
public RectangleF[] CnvsRects
{
get { return Rects; }
}
public Point ptstart = new Point(-10, -10);
public Point ptStart
{
get { return ptstart; }
set { ptstart = value; }
}
public Point ptend = new Point(-10, -10);
public Point ptEnd
{
get { return ptend; }
set { ptend = value; }
}
public new Image Image
{
get
{
RaisePictureBoxImageChange();
return base.Image ;
}
set
{
base.Image = value;
RaisePictureBoxImageChange();
}
}
void RaisePictureBoxImageChange()
{
EventImageArgs args = new EventImageArgs(base.Image, ptStart, ptEnd);
if(!(ptStart.Equals(new Point(-10,-10)) || ptEnd.Equals(new Point(-10,-10))))
OnRaisePictureBoxImageChange(args);
}
protected virtual void OnRaisePictureBoxImageChange(EventImageArgs ea)
{
if (PictureBoxImageChange != null)
{
PictureBoxImageChange(this, ea);
}
}
private void InitializeComponent()
{
((System.ComponentModel.ISupportInitialize)(this)).BeginInit();
this.SuspendLayout();
//
// Canvas
//
this.Margin = new System.Windows.Forms.Padding(0);
this.SizeMode = System.Windows.Forms.PictureBoxSizeMode.AutoSize;
((System.ComponentModel.ISupportInitialize)(this)).EndInit();
this.ResumeLayout(false);
}
}
public class EventImageArgs : EventArgs
{
private Image image;
public Image Image
{
get { return image; }
set { image = value; }
}
private Point points;
public Point ptStart
{
get { return points; }
set { points = value; }
}
private Point pointe;
public Point ptEnd
{
get { return pointe; }
set { pointe = value; }
}
public EventImageArgs(Image img,Point sp,Point ep)
{
image = img;
points = sp;
pointe = ep;
}
}
で、変化のあったポイントをイベントを通じて得て、そのポイントの含んでるRectangleをGraphic.FillRectangleを使ってその四角形を塗りつぶそうと思ったのですか、どうやって、そのポイント群を得るのかがわかりませんでした。
ですので、16×16ピクセルの画像を拡大して、処理をしていったほうがいいのかなと、思って最初の質問しました。
ただ、このクラスをつかって変化のあったポイントを知る方法があるなら、是非そちらの方が知りたいです。
変な質問の仕方をしてすいませんでした。
