Forking Picasso

history masters thesis Recently I started using this nice library, Picasso, for my Android projects.
Basically it’s a library which allows you to load any type of images (local or remote, assets or resources) asynchronously into your ImageView. It will load them in background for you, this not blocking the UI. It has also an internal cache system and it also comes with some useful features like “fade” ( when an image is loaded into the view it will automatically create a fade in effect ), “transform” ( you want to post transform the loaded bitmap ), “resize”, “fit” and more.

// creating a cache object with 1MB max size
Cache cache = new LruCache( 1024*1024*1 );

// now create a new request which will use this cache object
Picasso.with( this ).load( file ).withCache( myCache ).into( imageView );

home work assignment Generators can be used to load images which cannot be loaded using the common scheme convention. There are different situations when you need to generate a Bitmap which is not directly related to a file or url or even a real bitmap resource.

A Generator is a simple interface with only one method:

public RequestCreator resizeDimen(int targetWidthResId, int targetHeightResId, boolean onlyIfBigger);
public RequestCreator resize(int targetWidth, int targetHeight, boolean onlyIfBigger);

follow basically you can pass an option to skip the resize operation if the loaded bitmap is smaller than the passed `targetWidth` and `targetHeight`

here I’ve added a method `withOptions` in the RequestCreator which allow you to pass your own Options object which will be used to decode the image.
Example:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Config.RGB_565;

Picasso.with(this)

   .into(imageView);

    http://foto8.ch/brighton-rock-essay-help/ I really like the idea of Generator that allows me to provide my custom bitmap decode method.
    Good work!
    btw, any chance of making a pull request and have these nice features merged to master branch? 🙂

    • source link Thank you. I already did a pull request, but because of the many changes ( not only generators, I made other changes ) it was declined. That’s why I also published the fork on maven central.
