| byte& bytePixel | ( | gevd_bufferxy & | buf, |
| int | x, | ||
| int | y | ||
| ) | [inline] |
Get reference to pixel as a byte/char, unsigned/signed char (8-bit) number, at indexes (x, y) in buf.
This function is used to get and set pixel on non-const gevd_bufferxy.
Definition at line 55 of file gevd_pixel.h.
| const byte& bytePixel | ( | const gevd_bufferxy & | buf, |
| int | x, | ||
| int | y | ||
| ) | [inline] |
Get reference to pixel as a byte, at indexes (x, y).
Definition at line 106 of file gevd_pixel.h.
| char& charPixel | ( | gevd_bufferxy & | buf, |
| int | x, | ||
| int | y | ||
| ) | [inline] |
Get reference to pixel as a byte/char, unsigned/signed char (8-bit) number, at indexes (x, y) in buf.
This function is used to get and set pixel on non-const gevd_bufferxy.

| const char& charPixel | ( | const gevd_bufferxy & | buf, |
| int | x, | ||
| int | y | ||
| ) | [inline] |
Get reference to pixel as a char, at indexes (x, y).
Definition at line 115 of file gevd_pixel.h.
| float& floatPixel | ( | gevd_bufferxy & | buf, |
| int | x, | ||
| int | y | ||
| ) | [inline] |
Get reference to pixel as a float number, at indexes (x, y) in buf.
float is generally used to avoid overflow and unnecessary conversion between float/double for math computation and byte/short for storage.
Definition at line 90 of file gevd_pixel.h.
| const float& floatPixel | ( | const gevd_bufferxy & | buf, |
| int | x, | ||
| int | y | ||
| ) | [inline] |
Get reference to pixel as a float, at indexes (x, y).

| void*& ptrPixel | ( | gevd_bufferxy & | buf, |
| int | x, | ||
| int | y | ||
| ) | [inline] |
Get reference to pixel as a pointer, at indexes (x, y).

| void* const& ptrPixel | ( | const gevd_bufferxy & | buf, |
| int | x, | ||
| int | y | ||
| ) | [inline] |
Get const reference to pixel at indexes (x, y).
This function is used to get pixel on const gevd_bufferxy, as a const reference to a byte/char/short/float/void*.
Definition at line 149 of file gevd_pixel.h.
