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 are noticeable. |
bicub | Selects bi-cubic interpolation. More CPU-intensive than bi-linear interpolation, but yields sharper images with less noticeable aliasing artifacts. |
sharp2 | Selects a modified Lanczos Window function as an interpolation algorithm. Can 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 sharp has been replaced by sharp2 , which has a lesser likelihood of causing aliasing artifacts (Moiré).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. |
resMode=bisharp
and fit=stretch
, it is best practice to use either the width parameter or the height parameter. If both parameters must be defined, you can wrap them in a different layer as shown in the following example:/is/image/is/image/companyname?layer=0&src=is(companyname/imagename?wid=30&hei=30&fit=stretch)&resmode=bisharp
Properties
Request attribute. Applies to all scaling operations involved in creating the final reply image, including all layer scaling.
Default
attribute::ResMode
Example
Retrieve a best-quality rendition of a layered image stored in an image catalog. The image can include text. The image is further processed in an image editing application, and thus request an alpha-channel with the image.
