transformed by the optional matrix.

Returns a immutable bitmap with the specified width and height, with each

pixel value set to the corresponding value in the colors array.

Returns a immutable bitmap with the specified width and height, with each

pixel value set to the corresponding value in the colors array.

CreateBitmap(DisplayMetrics, Int32[], Int32, Int32, Int32, Int32, Bitmap+Config)

Returns a immutable bitmap with the specified width and height, with each

pixel value set to the corresponding value in the colors array.

[Android.Runtime.Register("createBitmap", "(Landroid/util/DisplayMetrics;[IIIIILandroid/graphics/Bitmap$Config;)Landroid/graphics/Bitmap;", "", ApiSince=17)]

public static Android.Graphics.Bitmap CreateBitmap (Android.Util.DisplayMetrics display, int[] colors, int offset, int stride, int width, int height, Android.Graphics.Bitmap.Config config);

static member CreateBitmap : Android.Util.DisplayMetrics * int[] * int * int * int * int * Android.Graphics.Bitmap.Config -> Android.Graphics.Bitmap

Parameters

Display metrics for the display this bitmap will be

drawn on.

colors

T:Android.Graphics._Color

offset

Number of values to skip before the first color in the

array of colors.

stride

Number of colors in the array between rows (must be >=

width or <= -width).

width

The width of the bitmap

height

The height of the bitmap

The bitmap config to create. If the config does not

support per-pixel alpha (e.g. RGB_565), then the alpha

bytes in the colors[] will be ignored (assumed to be FF)

Returns

Exceptions

if the width or height are <= 0, or if

the color array's length is less than the number of pixels.
