## 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.
