Parameters

buffer  T

A preallocated array to be used as the underlying buffer for the returned IReadWriteBitmapData. It can be larger than it is required for the specified parameters. If the actual image data starts at some offset use the CreateBitmapDataT(ArraySectionT, Size, Int32, CustomBitmapDataConfig) overload instead.

size  Size

The size of the bitmap data to create in pixels.

stride  Int32

The size of a row in bytes. It allows to have some padding at the end of each row.

customBitmapDataConfig  CustomBitmapDataConfig

The configuration for the custom pixel format. At least one getter or setter delegate must be specified. If you can ensure that the delegates don't capture buffer make sure you set the BackBufferIndependentPixelAccess property to .

Type Parameters

T

The type of the elements in buffer.

Return Value

This method allows creating an IReadWriteBitmapData instance with custom pixel format. You need to specify a PixelFormatInfo and at least one delegate setter or getter delegate to be called whenever a pixel is get or set. In this overload these can be done by assigning a CustomBitmapDataConfig instance to the customBitmapDataConfig parameter. The desired PixelFormatInfo should be set in the PixelFormat property, whereas for the getter and setter methods you can select the ones with the color types that fit the best for your pixel format.

A custom pixel format can have any BitsPerPixel value between 1 and 128. A typical bits-per-pixel value is a power of two; however, any other value can be used if you handle them in the provided delegates.

The getter and setter delegates are always called with an x coordinate meaning the pixel offset in the corresponding row.
