SoBitmap

SoBitmap is not an ImageLoader, it born for process single bitmap. Some conditions, we want a image displayed in some limit, such as the max size, the memory cost and its format. SoBitmap handle these all for you, then release you to concern the real important things. You can totally use SoBitmap as a black box, the only things you need care are the input configuration and the output bitmap.

Feature

• support local file, MediaStore and network stream
• support two config way:

1. exact limit include max input, max output, and compress quality down step
2. fuzzy limit that you only need set a level or just by default.

• use okhttp as httpclient for downloading, I think we can trust it(Shall we have a choice about it?)
• all callback heppen in UI thread, so relax about it

Usage

Include in your project

• Gradle

repositories {
    maven { url "https://oss.sonatype.org/content/repositories/snapshots" }

Custom display option

Exactly

Options.ExactOptionsBuilder builder = new Options.ExactOptionsBuilder();
builder.step(10)
        .format(Bitmap.CompressFormat.JPEG)
        .maxOutput(200)
        .maxInput(10 * 1000)
        .maxSize(5000);
Options ops = builder.build();

Fuzzy

Options.FuzzyOptionsBuilder builder = new Options.FuzzyOptionsBuilder();
builder.maxSize(5000)
        .format(Bitmap.CompressFormat.PNG)
        .level(Options.QualityLevel.HIGH);
Options ops = builder.build();

Change the default option

SoBitmap.getInstance(context).setDefaultOption(myCustomOps);

Hunting bitmap

SoBitmap.getInstance(this).hunt(uri, new Callback() {
            @Override
            public void onHunted(Bitmap bitmap, BitmapFactory.Options options) {
                imageView.setImageBitmap(bitmap);
            }

            @Override
            public void onException(HuntException e) {
                textView.setText(e.toString());
            }
        });

• Multi thread speed up the decoding duration
