我遇到了PictureBox
在不同分辨率之间大小不同的问题。
我有一个图像需要放入PictureBox
中,但我需要知道它的绘图大小,因为我需要自己调整大小(否则系统太慢了,我决定手动调整大小,如果我知道需要的分辨率,这很好)。
我尝试了PictureBox.Height / Width
和PictureBox.ClientRectangle.Height / Width
,但所有分辨率的值都是相同的。如何获得实际的图纸尺寸?
初始化代码:
//
// PicboxRed
//
this.PicboxRed.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom)
| System.Windows.Forms.AnchorStyles.Left)
| System.Windows.Forms.AnchorStyles.Right)));
this.PicboxRed.BackColor = System.Drawing.Color.DimGray;
this.PicboxRed.BackgroundImageLayout = System.Windows.Forms.ImageLayout.Center;
this.PicboxRed.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D;
this.PicboxRed.Location = new System.Drawing.Point(19, 92);
this.PicboxRed.Margin = new System.Windows.Forms.Padding(4, 4, 4, 4);
this.PicboxRed.Name = "PicboxRed";
this.PicboxRed.Size = new System.Drawing.Size(852, 840);
this.PicboxRed.SizeMode = System.Windows.Forms.PictureBoxSizeMode.Normal;
this.PicboxRed.TabIndex = 9;
this.PicboxRed.TabStop = false;
this.PicboxRed.Click += new System.EventHandler(this.PicboxRed_Click);
this.PicboxRed.Paint += new System.Windows.Forms.PaintEventHandler(this.Picbox_Paint);
我知道这与正在设置的锚点有关,但这允许PictureBox以不同的分辨率被很好地看到。我该如何获取真正的绘图区域?
ClientSize属性告诉它有多大。ClientSizeChanged事件告诉您它何时因任何原因更改,包括由于窗体的AutoScaleMode属性而自动缩放。
I tried PictureBox.Height / Width, and PictureBox.ClientRectangle.Height / Width, but that values are the same for all resolutions.
我想你正在寻找dpi设置:
int currentDPI = 0;
using (Graphics g = this.CreateGraphics())
{
currentDPI = (int)g.DpiX;
}
此值应在具有不同分辨率和dpi设置的计算机上更改。
或者,您可能对获取当前屏幕分辨率感兴趣。它们可能会有所帮助:
Rectangle resolution = Screen.PrimaryScreen.Bounds;
