 As it is well known, `Bitmap.SetPixel`/`GetPixel` methods are very slow. Additionally, they do not support every pixel format. A typical solution can be to obtain a `BitmapData` by the `LockBits` method, which has further drawbacks: you need to use unsafe code and pointers, and the way you need to access the bitmap data depends on the actual `PixelFormat` of the bitmap.

 The [`BitmapDataFactory`](https://docs.kgysoft.net/drawing/html/T_KGySoft_Drawing_Imaging_BitmapDataFactory.htm) class has many [`CreateBitmapData`](https://docs.kgysoft.net/drawing/html/Overload_KGySoft_Drawing_Imaging_BitmapDataFactory_CreateBitmapData.htm) overloads. The ones whose first parameter is `Size` allocate the underlying buffer by themselves, which is not directly accessible from outside. But you are also able to use predefined arrays of any primitive element type (one or two dimensional ones), and also [`ArraySection<T>`](https://docs.kgysoft.net/corelibraries/html/T_KGySoft_Collections_ArraySection_1.htm) or [`Array2D<T>`](https://docs.kgysoft.net/corelibraries/html/T_KGySoft_Collections_Array2D_1.htm) buffers to create a managed bitmap data for.

 The previous example demonstrated how we can create a managed accessor for a `WriteableBitmap`. But it worked only because we used a pixel format that happen to have built-in support also in KGy SOFT Drawing Libraries. In fact, the libraries provide support for any custom pixel format. The [`CreateBitmapData`](https://docs.kgysoft.net/drawing/html/Overload_KGySoft_Drawing_Imaging_BitmapDataFactory_CreateBitmapData.htm) methods have several overloads that allow you to specify a custom pixel format along with a couple of delegates to be called when pixels are read or written:

 Note that there are different overloads for indexed formats where you have to specify how to read/write a palette index. Please also note that these delegates work with 32-bit color structures (just like usual `GetPixel`/`SetPixel`) so wider formats will be quantized into the ARGB8888 color space (or BGRA8888, using the alternative terminology) when getting/setting pixels but this is how regular formats work, too. Anyway, you can always access the actual underlying data of whatever format by the aforementioned [`IReadableBitmapDataRow.ReadRaw`](https://docs.kgysoft.net/drawing/html/M_KGySoft_Drawing_Imaging_IReadableBitmapDataRow_ReadRaw__1.htm) and [`IWritableBitmapDataRow.WriteRaw`](https://docs.kgysoft.net/drawing/html/M_KGySoft_Drawing_Imaging_IWritableBitmapDataRow_WriteRaw__1.htm) methods.
