Is it possible to blur sprite or whole screen? I'm using dbSprite not bitmaps. I have no 3d objects.

void dbBlurBitmap ( int iBitmap, int iBlur ); // iBitmap 0 will blur the screen.

To blur a sprite, I would prepare the images first.

dbLoadImage ( "sprite.bmp" , 1 ); // Load the sprite image
dbCreateBitmap ( 1, 32, 32 ); // Create a bitmap the same size as the sprite image.
dbPasteImage ( 1, 0, 0 ); // Paste the image to bitmap 1
dbBlurBitmap ( 1, 6 ); // Blur bitmap 1, second value is blur amound (1 - 6)
dbGetImage ( 2, 0, 0, 32, 32 ); // Get image 2 after blurring the bitmap
dbSetCurrentBitmap ( 0 ); //Set current bitmap back to the screen
dbDeleteBitmap ( 1 ); // Delete the bitmap

Just switch the image number in the dbSprite command to show the normal or blured sprite image.

The method proposed would only need to be done once. If you are wanting to blur them on-the-fly, then that's a tall order. Give an example of what you are trying to achieve.

The fastest code is the code never written.

Blue as in the color? or blur?

There may be some "post processing" .fx out there. Sorry I have never tried that.

This may help, but I don't know if it will work on 2D.....
