Why this function throw me error exception out of memory after working on 300-400 images ?

[EDN Admin]

<div style="color:Black;background-color:White; <pre>
<span style="color:Blue; private Bitmap converttoBlackAndWhite(Bitmap original)
{

Bitmap newBitmap = <span style="color:Blue; new Bitmap(original.Width, original.Height);

<span style="color:Green; //get a graphics object from the new image
Graphics g = Graphics.FromImage(newBitmap);

<span style="color:Green; //create the grayscale ColorMatrix
ColorMatrix colorMatrix = <span style="color:Blue; new ColorMatrix(
<span style="color:Blue; new <span style="color:Blue; float[][]
{
<span style="color:Blue; new <span style="color:Blue; float[] {.3f, .3f, .3f, 0, 0},
<span style="color:Blue; new <span style="color:Blue; float[] {.59f, .59f, .59f, 0, 0},
<span style="color:Blue; new <span style="color:Blue; float[] {.11f, .11f, .11f, 0, 0},
<span style="color:Blue; new <span style="color:Blue; float[] {0, 0, 0, 1, 0},
<span style="color:Blue; new <span style="color:Blue; float[] {0, 0, 0, 0, 1}
});

<span style="color:Green; //create some image attributes
ImageAttributes attributes = <span style="color:Blue; new ImageAttributes();

<span style="color:Green; //set the color matrix attribute
attributes.SetColorMatrix(colorMatrix);

<span style="color:Green; //draw the original image on the new image
<span style="color:Green; //using the grayscale color matrix
g.DrawImage(original, <span style="color:Blue; new Rectangle(0, 0, original.Width, original.Height),
0, 0, original.Width, original.Height, GraphicsUnit.Pixel, attributes);

<span style="color:Green; //dispose the Graphics object
g.Dispose();
<span style="color:Blue; return newBitmap;
}
[/code]

The function converting the images to grayScale to gray(black and white).
Then after its working for some im getting error: Out of memory

Exception error:

InnerException:

The error is on the line:

g.DrawImage(original, new Rectangle(0, 0, original.Width, original.Height),<br/>
0, 0, original.Width, original.Height, GraphicsUnit.Pixel, attributes);

The reason im using this finction since its working fast !

Thanks. <hr class="sig danieli
