ICustomBitmapDataRowUnsafeGetRefAsT Method
Gets a reference to a value interpreted as
T within the current row at the specified
x index.
This method is similar to
GetRefAsT(Int32) but it does not check whether
x is valid for
RowSize and the size of
T.
It may provide a better performance but if
x is invalid, then memory can be either corrupted or an
AccessViolationException can be thrown.

- x Int32
- The x-coordinate of the value within the row to retrieve. The valid range depends on the size of T.
- T
- The type of the value to return a reference for. Must be a value type without managed references.
TA reference to a value interpreted as
T within the current row at the specified
x index.
If
T is a primitive type of size greater than 1 byte (for example
int,
float, etc.),
then the address of the result should be aligned to the size of
T. On most platforms misalignment affects only performance,
but depending on the architecture, dereferencing the returned misaligned managed pointer may provide an unexpected result, or can even throw a
DataMisalignedException.
