534 | * please take note of the following caveats when using these: |
||
535 | * - Scaling is done using only 7bit instead of 14bit coefficients. |
||
536 | * - You can use no more than 5 input pixels to produce 4 output |
||
537 | * pixels. Therefore, this filter should not be used for downscaling |
||
538 | * by more than ~20% in width (because that equals more than 5/4th |
||
539 | * downscaling and thus more than 5 pixels input per 4 pixels output). |
||
540 | * - In general, bilinear filters create artifacts during downscaling |
||
541 | * (even when <20%), because one output pixel will span more than one |
||
542 | * input pixel, and thus some pixels will need edges of both neighbor |
||
543 | * pixels to interpolate the output pixel. Since you can use at most |
||
544 | * two input pixels per output pixel in bilinear scaling, this is |
||
545 | * impossible and thus downscaling by any size will create artifacts. |
||
546 | * To enable this type of scaling, set SWS_FLAG_FAST_BILINEAR |
||
547 | * in SwsContext->flags. |
