FlatRedBall.Graphics.Texture.ImageData.ApplyColorOperation

Introduction

ApplyColorOperation is a method which can be used to modify an ImageData using the same ColorOperation and Red,Green,Blue values that are present in the IColorable interface which is implemented by common FlatRedball objects such as Sprite and Text.

ApplyColorOperation modifies the data stored in an ImageData permanently – it cannot be undone.

Code Example

ApplyColorOperation can be used to modify a texture so that when rendered normally, it will appear the same as a Sprite with the same ColorOperation and Red/Green/Blue values. The following code shows a texture being rendered using a Modulate color operation:

 Texture2D texture = FlatRedBallServices.Load<Texture2D>("redball.bmp");
 
 ImageData imageData = ImageData.FromTexture2D(texture);
 
 float red = 0;
 float green = .5f;
 float blue = .5f;
 float alpha = 1;
 
 imageData.ApplyColorOperation(ColorOperation.Modulate, red, green, blue, alpha);
 
 Texture2D modified = imageData.ToTexture2D();
 
 Sprite sprite = SpriteManager.AddSprite(modified);
 
 Sprite originalSprite = SpriteManager.AddSprite("redball.bmp");
 originalSprite.X = 2;
 
 SpriteManager.Camera.BackgroundColor = Color.White;
