Member Function Documentation

static csRef<iImage> csImageManipulate::Blur ( iImage source,
csRGBpixel transp = 0 
) [static]

Return a blurred version of the image.

static csRef<iImage> csImageManipulate::Crop ( iImage source,
int  x,
int  y,
int  width,
int  height 
) [static]

Create a new image and copy a subpart of the actual image into the new image.

static csRef<iImage> csImageManipulate::Mipmap ( iImage source,
int  step,
csRGBpixel transp = 0 
) [static]

Create a new iImage which is a mipmapped version of this one.

'step' indicates how much the mipmap should be scaled down. Step 0 returns the original image. Step 1 scales the image down to 1/2. Steps > 1 repeat this 'step' times. The new image will have same format as the original one. If you pass a pointer to a transparent color, the texels of that color are handled differently.

static csRef<iImage> csImageManipulate::Rescale ( iImage source,
int  NewWidth,
int  NewHeight,
int  NewDepth = 1 
) [static]

Rescale an image to the given size.

static csRef<iImage> csImageManipulate::Sharpen ( iImage source,
int  strength,
csRGBpixel transp = 0 
) [static]

Create a sharpened copy of the image.

The effect of 'strength' differs from image to image. Values around 128-512 give good results. On really blurry images values up to 1024 or 2048 can be used.
