D2Phap.DXControl 1.0.2

DXControl

• A WinForms hybrid control that supports Direct2D and GDI+ drawing thanks to DirectN and WicNet.
• This control is used in ImageGlass software since version 9.0.

• Project url: https://github.com/d2phap/DXControl
• Nuget package: https://www.nuget.org/packages/D2Phap.DXControl
• About: https://imageglass.org/about

Features

• High performance drawing using Direct2D.
• Names and types are exactly the same as the native concepts of Direct2D (interfaces, enums, structures, constants, methods, arguments, guids, etc...). So you can read the official documentation, use existing C/C++ samples, and start coding with .NET right away.
• All native COM interfaces are generated as .NET (COM) interfaces, this makes .NET programming easier, but they are not strictly needed.
• Option to draw by GDI+.
• Supports animation drawing for both Direct2D and GDI+.

Requirements:

• .NET 6.0

Installation

Run the command

Install-Package D2Phap.DXControl

Example

Draw 2 rectangles by Direct2D and GDI+ graphics, then animate it to the right side.

using D2phap;

// create a WinForms custom control that extends from DXControl
public class DXCanvas : DXControl
{
    private D2D_RECT_F animatableRectangle = new(100f, 100f, new(400, 200));

    public DXCanvas()
    {
        EnableAnimation = true;
    }

    // use Direct2D graphics
    protected override void OnRender(DXGraphics g)
    {
        // draw a yellow rectangle with green border
        g.FillRectangle(rectText, _D3DCOLORVALUE.FromCOLORREF(_D3DCOLORVALUE.Yellow.Int32Value, 100));
        g.DrawRectangle(rectText, _D3DCOLORVALUE.Green);
    }


    // Use GDI+ graphics
    protected override void OnRender(Graphics g)
    {
        // draw a yellow rectangle with green border
        using var pen = new Pen(Color.Red, 5);
        g.DrawRectangle(pen, new Rectangle((int)rectText.left, (int)rectText.top - 50, (int)rectText.Width, (int)rectText.Height));
    }


    // Update frame logics for animation
    protected override void OnFrame(FrameEventArgs e)
    {
        // animate the rectangle to the right
        animatableRectangle.left++;
    }
}
