image_transformer

A Pub tranformer for converting between image formats. Sometimes you need to convert the image files of your applications to different formats. If your designers hand their assets as PSD files, you need to convert them first to browser supported format. This packages provides a pub transformer to convert between different image formats.

This package don't require any additional tools for image conversion due to the great work of Brendan Duncan and his image package.

Configuration

The next step is configurating the transformer for your package. Add it to the dependencies and transformers sections of your pubspec.yaml and add the desired options. The following example converts psd files to png :

transformers:
   - image_transformer:
       input_extensions: '.psd'
       output_extension: '.png'

You can add multiple instances of the transformer to your pubspec.yaml if you need the files in different output formats.

Supported formats

I try to keep track with the formats supported by the image package. At the moment the following formats are supported for both input and output formats:

  • PNG
  • JPG
  • TGA
  • GIF

Input only:

  • WebP
  • TIFF
  • Photoshop PSD
  • OpenEXR

input_extensions

A input extension or a list of input extensions that should be processed.

output_extension

The extension of the format to output.
