ResamplingMethod enum
Resampling method.
Values
- NONE → const ResamplingMethod
-
Always geometrically rescale the image to fit the page if necessary. Fast.
Otherwise, downscale the bitmap to match the
dpisetting via the selected method before adding it to the PDF if the calculated image DPI after stretching is greater thandpi. Slower. - NEAREST → const ResamplingMethod
-
Nearest-neighbor interpolation. Lowest quality. Produces blocky images, especially when upsampling.
- LINEAR → const ResamplingMethod
-
Bi-linear interpolation. Better quality than nearest-neighbor, slower. Okay when the target size is not too different from the source size.
- CUBIC → const ResamplingMethod
-
Bi-cubic interpolation. Better quality than bi-linear, slower. Produces high-quality results in a larger range than that of bi-linear.
- LANCZOS4 → const ResamplingMethod
-
Lanczos (Sinc) interpolation over 8x8 neighborhood. Produces very high quality results, but slower than bi-cubic. Retains sharp edges like those of text when downsampling.
- AREA → const ResamplingMethod
-
Accurate, produces moire-free results, but tends to produce blurrier images. When upsampling, it is similar to nearest-neighbor.
