Method ExtMisc.Resize(+ 1 overload)

---

Overload

Resizes this image.

public static Bitmap Resize(this Bitmap b, int width, int height, BRFilter filter, bool dispose, bool premultiplied = false)

Parameters

b  (Bitmap)

width  (int) New width.

height  (int) New height. If width or height is 0, calculates it (preserves aspect ratio).

filter  (BRFilter) Enum: Lanczos3, CatmullRom, Bicubic.

dispose  (bool) When resized, call Dispose for this object.

premultiplied  (bool) Let the resized bitmap have PixelFormat = Format32bppPArgb. It prevents distortions at transparent-opaque boundaries. If false: if this bitmap has Format32bppArgb or Format32bppPArgb, does not change, else PixelFormat.Format32bppArgb.

Returns

Bitmap Resized image (new object). Returns this image if new width and height would be the same as of this image.

Exceptions

ArgumentException Unsupported PixelFormat.

Overload(top)

Resizes this image.

public static Bitmap Resize(this Bitmap b, double factor, BRFilter filter, bool dispose, bool premultiplied = false)

Parameters

b  (Bitmap)

factor  (double) Scaling factor. For example 2 to make 2 times bigger, or 0.5 to make 2 times smaller.

filter  (BRFilter) Enum: Lanczos3, CatmullRom, Bicubic.

dispose  (bool) When resized, call Dispose for this object.

premultiplied  (bool) Let the resized bitmap have PixelFormat = Format32bppPArgb. It prevents distortions at transparent-opaque boundaries. If false: if this bitmap has Format32bppArgb or Format32bppPArgb, does not change, else PixelFormat.Format32bppArgb.

Returns

Bitmap Resized image (new object). Returns this image if new width and height would be the same as of this image.

Exceptions

ArgumentException Unsupported PixelFormat.
