Constructors
| SKMask(IntPtr, SKRectI, UInt32, SKMaskFormat) |
Creates an instance of SKMask with the specified configuration. |
| SKMask(SKRectI, UInt32, SKMaskFormat) |
Creates an instance of SKMask with the specified configuration, but a null Image. |
Properties
| Bounds |
Gets the bounds of the mask in the image. |
| Format |
Gets the format of the mask image. |
| Image |
Get the pointer to the mask's image data location. |
| IsEmpty |
Gets a value indicating whether the mask's bounds are empty. |
| RowBytes |
Gets the number of bytes per row. |
Methods
| AllocateImage() |
Allocates a memory block for the mask's image. |
| AllocateImage(Int64) |
Allocates a memory block for a mask's image. |
| ComputeImageSize() |
Calculates the byte size of the mask, assuming only 1 plane. |
| ComputeTotalImageSize() |
Calculates the byte size of the mask, taking into account any extra planes (e.g. ThreeD). |
| Create(Byte[], SKRectI, UInt32, SKMaskFormat) |
Creates an instance of SKMask with the specified configuration, and copies the image data. |
| Create(ReadOnlySpan<Byte>, SKRectI, UInt32, SKMaskFormat) | |
| Equals(Object) | |
| Equals(SKMask) | |
| FreeImage() |
De-allocate the mask's image data. |
| FreeImage(IntPtr) |
De-allocate the specified mask image data. |
| GetAddr(Int32, Int32) |
Returns the address of the specified pixel, computing the pixel-size at runtime based on the mask format. |
| GetAddr1(Int32, Int32) |
Returns the bit value of the specified specified pixel. |
| GetAddr16(Int32, Int32) |
Returns the 16-bit value of the specified specified pixel. |
| GetAddr32(Int32, Int32) |
Returns the 32-bit value of the specified specified pixel. |
| GetAddr8(Int32, Int32) |
Returns the 8-bit value of the specified specified pixel. |
| GetHashCode() | |
| GetImageSpan() | |
Operators
| Equality(SKMask, SKMask) | |
| Inequality(SKMask, SKMask) |
