Creates a new bitmap, scaled from an existing bitmap, when possible.
[Android.Runtime.Register("createScaledBitmap", "(Landroid/graphics/Bitmap;IIZ)Landroid/graphics/Bitmap;", "")]
public static Android.Graphics.Bitmap CreateScaledBitmap (Android.Graphics.Bitmap src, int dstWidth, int dstHeight, bool filter);[<Android.Runtime.Register("createScaledBitmap", "(Landroid/graphics/Bitmap;IIZ)Landroid/graphics/Bitmap;", "")>]
static member CreateScaledBitmap : Android.Graphics.Bitmap * int * int * bool -> Android.Graphics.BitmapParameters
- src
- Bitmap
The source bitmap.
- dstWidth
- Int32
The new bitmap's desired width.
- dstHeight
- Int32
The new bitmap's desired height.
- filter
- Boolean
Whether or not bilinear filtering should be used when scaling the bitmap. If this is true then bilinear filtering will be used when scaling which has better image quality at the cost of worse performance. If this is false then nearest-neighbor scaling is used instead which will have worse image quality but is faster. Recommended default is to set filter to 'true' as the cost of bilinear filtering is typically minimal and the improved image quality is significant.
Returns
The new scaled bitmap or the source bitmap if no scaling is required.
- Attributes
Exceptions
if width is <= 0, or height is <= 0
Remarks
Creates a new bitmap, scaled from an existing bitmap, when possible. If the specified width and height are the same as the current width and height of the source bitmap, the source bitmap is returned and no new bitmap is created.
