◆ alignment
| size_t alignment |
Specifies the alignment of the address of the buffer's memory.
Setting this to 0 lets the buffer pool select an alignment automatically.
The alignment must be a power of 2.
◆ buffer_size
| size_t buffer_size |
Overrides the automatic buffer size calculation.
A value of 0 lets the buffer pool calculate the required buffer size automatically.
Setting a size that is smaller than the amount of memory required to store an image of a known format will lead to an error.
◆ pitch
| ptrdiff_t pitch |
Specifies the pitch to use when allocating the buffer.
A value of 0 lets the buffer pool select a pitch automatically.
Setting a pitch that is smaller than the amount of memory required to store one line of image data will lead to an error.
