RIG – Random Image Generator

A library for Android that generates random Bitmap images. Generation is performed on the basis of different passed parameters like width, height, type of generator, color palette, etc. Images can be also automatically saved in the requested path with appropriate quality.

Usage

Simple example with callback:

new Rig.Builder()
        .setGenerator(generator)
        .setFixedSize(1920, 1080) // can be also 1x1, 1x1000, etc
        .setCount(10)
        .setCallback(new GenerateCallback() {
            @Override
            public void onGenerated(ImageParams imageParams, Bitmap bitmap) {
                // will be called 10 times with a new bitmap 1920x1080 on every call
            }
            @Override
            public void onFailedToGenerate(ImageParams imageParams, Exception e) {
                // in case if generation failed
            }
        })
        .build()
        .generate();

Simple example with compression:

new Rig.Builder()
        .setGenerator(generator)
        .setFixedSize(1920, 1080) // can be also 666x666, 1337x1337, etc
        .setQuality(Quality.jpg(90))
        .setFileSavePath(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getPath())
        .setFileSaveCallback(new SaveCallback() {
            @Override
            public void onSaved(Bitmap bitmap, File file) {
                // will be called when bitmap is saved
            }
            @Override
            public void onFailedToSave(Bitmap bitmap, Exception e) {
                // in case if compression failed
            }
        })
        .build()
        .generate();

For more information, please see Rig.Builder javadoc.

Embed generators

There are currently 6 generators, and 3 effects.

FlatColorGenerator

ColoredPixelsGenerator

ColoredRectangleGenerator

ColoredNoiseGenerator

ColoredCirclesGenerator

ColoredLinesGenerator

MirroredEffect

ThresholdEffect

TextOverlayEffect

Custom generators

To create your own generator, you just need to implement Generator interface:

public class MyGenerator implements Generator {
    @Override
    public Bitmap generate(ImageParams imageParams) throws Exception {
        // your generation here
    }
}

Color palette

By default, the library generates images with all available HSV colors. RigPalette class is used to change this palette.

Examples:

RigPalette.blackAndWhite()

RigPalette.fromColor(Color.RED)

RigPalette.fromColor(Color.GREEN)

RigPalette.fromColor(Color.BLUE)
