Package Exports
- gulp-imagemin
- gulp-imagemin/package.json
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (gulp-imagemin) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

options
Options are applied to the correct files.
optimizationLevel (png)
Type: number
Default: 3
Select an optimization level between 0 and 7.
The optimization level 0 enables a set of optimization operations that require minimal effort. There will be no changes to image attributes like bit depth or color type, and no recompression of existing IDAT datastreams. The optimization level 1 enables a single IDAT compression trial. The trial chosen is what. OptiPNG thinks it’s probably the most effective. The optimization levels 2 and higher enable multiple IDAT compression trials; the higher the level, the more trials.
Level and trials:
- 1 trial
- 8 trials
- 16 trials
- 24 trials
- 48 trials
- 120 trials
- 240 trials
