|
|
int | BufLen [2] |
| | Intermediate buffers' lengths in fptype elements.
|
| |
|
int | BufOffs [2] |
| | Offsets into the intermediate buffers, used to provide prefix elements required during processing so that no "out of range" access happens. This offset is a multiple of ElCount if pixels are stored in interleaved form.
|
| |
|
int | elalign |
| | Length alignment of arrays of elements. This applies to filters and intermediate buffers: this constant forces filters and scanlines to have a length which is a multiple of this value, for more efficient SIMD implementation.
|
| |
|
int | ElCount |
| | The number of fptype elements used to store 1 pixel.
|
| |
|
int | ElCountIO |
| | The number of source and destination image's elements used to store 1 pixel.
|
| |
|
int | fpalign |
| | Suggested alignment size in bytes. This is not a required alignment, because image resizing algorithm cannot be made to have a strictly aligned data access in all cases (e.g. de-interleaved interpolation cannot perform aligned accesses).
|
| |
|
int | fppack |
| | The number of atomic types stored in a single fptype element.
|
| |
|
double | InGammaMult |
| | Input gamma multiplier, used to convert input data to [0; 1] range. 0.0, if no gamma is in use.
|
| |
|
bool | IsResize2 |
| | Use optimized doResize2() function.
|
| |
|
double | k |
| | Resizing step coefficient, updated to reflect the actually used coefficient during resizing.
|
| |
|
double | o |
| | Starting pixel offset inside the source image, updated to reflect the actually used offset during resizing.
|
| |
|
double | OutGammaMult |
| | Output gamma multiplier, used to convert data to [0; 255/65535] range. 0.0, if no gamma is in use.
|
| |
|
int | packmode |
| | 0, if interleaved packing; 1, if de-interleaved.
|
| |
|
int | ResizeStep |
| | Index of the resizing step in the latest filtering steps array.
|

Image resizing variables (base class).
This is an utility "catch all" base class, which defines various variables used during image resizing.
