[英]visual c# - onPaint and transparency
我正在制作一個帶有兩個半透明文本的簡單表格,並將其放入繪畫事件中。 只有當我把形狀擴大時,文字會變得更暗,更有顆粒感。 我想要更深的顏色,但不是顆粒狀的效果。
這是我的代碼片段:
private void sbfToolBox_Paint(object sender, PaintEventArgs e)
{
System.Drawing.Graphics formGraphics = this.CreateGraphics();
formGraphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias;
string drawString = "tekst";
System.Drawing.Font drawFont = new System.Drawing.Font("Arial", 50);
Color color_red = Color.FromArgb(30, 100, 0, 0);
Color color_cyan = Color.FromArgb(30, 0, 100, 100);
System.Drawing.SolidBrush brush_red = new System.Drawing.SolidBrush(color_red);
System.Drawing.SolidBrush brush_cyan = new System.Drawing.SolidBrush(color_cyan);
float x = 0.0F;
float x2 = 20.0F;
float y = 50.0F;
formGraphics.DrawString(drawString, drawFont, brush_red, x, y);
formGraphics.DrawString(drawString, drawFont, brush_cyan, x2, y);
drawFont.Dispose();
brush_red.Dispose();
brush_cyan.Dispose();
formGraphics.Dispose();
}
提前致謝
使用PaintEventArgs中的Graphics對象。
更改
System.Drawing.Graphics formGraphics = this.CreateGraphics();
至
System.Drawing.Graphics formGraphics = e.Graphics;
並刪除
formGraphics.Dispose();
