# Bitmap Constructor (Color, Int32, Int32, PixelFormat)
 
Creates new [Bitmap](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Bitmap.htm.md) instance of given dimensions and pixel format. Background color is specified.
 
**Namespace:** [Aurigma.GraphicsMill](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```
Public Sub New ( _background As Color, _width As Integer, _height As Integer, _format As PixelFormat _
)
```
 
```csharp
public Bitmap(Color background,int width,int height,PixelFormat format
)
```
 
### Parameters
 
 - background
     - Type: [Aurigma.GraphicsMill.Color](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Color.htm.md)
Background color to fill the bitmap with.

 - width
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
Width of new bitmap (in pixels).

 - height
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
Height of new bitmap (in pixels).

 - format
     - Type: [Aurigma.GraphicsMill.PixelFormat](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_PixelFormat.htm.md)
Pixel format of new bitmap. If you specify indexed pixel format, uninitialized palette will be generated. You must fill entries yourself. Palette will have maximum possible for given pixel format colors number (2 colors for 1-bit images, 16 colors for 4-bit images, and 256 colors for 8-bit images).
 
## Remarks
 If color space of the color does not fit color space of the pixel format, color is converted to necessary color space.
 
## Examples
  
```
Dim bitmap As New Aurigma.GraphicsMill.Bitmap( _
 Aurigma.GraphicsMill.RgbColor.White, 300, 30, _
 Aurigma.GraphicsMill.PixelFormat.Format24bppRgb)

Dim graphics As Aurigma.GraphicsMill.Drawing.GdiGraphics = bitmap.GetGdiGraphics

'Draw text
Dim font As New Aurigma.GraphicsMill.Drawing.Font("Futura Md BT", 20)
font.Bold = False
font.Italic = True
font.Underline = True
font.Strikeout = False
font.HorizontalAlignment = Aurigma.GraphicsMill.Drawing.HorizontalAlignment.Center

Dim brush As New Aurigma.GraphicsMill.Drawing.SolidBrush( _
 Aurigma.GraphicsMill.RgbColor.Red)

graphics.DrawString("Sample text", font, brush, 150, 0)
```
 
```csharp
Aurigma.GraphicsMill.Bitmap bitmap = new Aurigma.GraphicsMill.Bitmap(
    Aurigma.GraphicsMill.RgbColor.White, 300, 30, 
    Aurigma.GraphicsMill.PixelFormat.Format24bppRgb);

Aurigma.GraphicsMill.Drawing.GdiGraphics graphics = bitmap.GetGdiGraphics();

//Draw text
Aurigma.GraphicsMill.Drawing.Font font = 
    new Aurigma.GraphicsMill.Drawing.Font("Futura Md BT", 20);
font.Bold = false;
font.Italic = true;
font.Underline = true;
font.Strikeout = false;
font.HorizontalAlignment = Aurigma.GraphicsMill.Drawing.HorizontalAlignment.Center;

Aurigma.GraphicsMill.Drawing.SolidBrush brush = 
    new Aurigma.GraphicsMill.Drawing.SolidBrush(Aurigma.GraphicsMill.RgbColor.Red);

graphics.DrawString("Sample text", font, brush, 150, 0);
```
