Resampling mode. Chooses the resampling and/or interpolation algorithm to be used for scaling image data. Also applies to rotation of text layers and resizing of composite images during the view transform.
resMode=bilin|bicub|sharp2|bisharp
bilin |
Selects standard bi-linear interpolation. Fastest resampling method; some aliasing artifacts may be noticeable. |
bicub |
Selects bi-cubic interpolation. More CPU-intensive than bi-linear interpolation, but will yield sharper images with less noticeable aliasing artifacts. |
sharp2 |
Selects a modified Lanczos Window function as an interpolation algorithm. May produce slightly sharper results than bi-cubic at a higher CPU cost. sharp has been replaced by sharp2 , which has a lesser likelihood of causing aliasing artifacts (Moiré). |
bisharp |
Selects Photoshop default resampler for reducing image size which is called "bicubic sharper" in Adobe Photoshop. |
Request attribute. Applies to all scaling operations involved in creating the final reply image, including all layer scaling.
attribute::ResMode
Retrieve a best-quality rendition of a layered image stored in an image catalog. The image might include text. We expect to further process in an image editing application, and thus request an alpha-channel with the image.
