示例1: test
test('write image to disk', async () => {
const img = getTestImage();
const destination = join(tmpDir, 'image.png');
await write(destination, img);
expect(existsSync(destination)).toBe(true);
const imgRead = await read(destination);
expect(imgRead).toStrictEqual(img);
});示例2: test
test('read existing image', async () => {
const img = await read(getPath('rgba32.png'));
expect(img).toBeInstanceOf(Image);
expect(img).toMatchObject({
width: 30,
height: 90,
kind: ImageKind.RGBA
});
});示例3: it
it('blur compared to opencv', async () => {
const img = getTestImage();
const blurred = blur(img, {
width: 3,
height: 5,
borderType: BorderType.REFLECT
});
const expected = await read('test/img/testBlur.png');
expect(blurred.data).toStrictEqual(expected.data);
});示例4: it
it('direct convolution compared to opencv', async () => {
const img = getTestImage();
const kernelY = Matrix.columnVector([0.4, 0.5, 0.6, -0.3, -0.4]);
const kernelX = Matrix.rowVector([0.1, 0.2, 0.3]);
const kernel = kernelY.mmul(kernelX).to2DArray();
const convoluted = directConvolution(img, kernel, {
borderType: BorderType.REFLECT
});
const expected = await read('test/img/testConv.png');
expect(convoluted.data).toStrictEqual(expected.data);
});示例5: async
it.skip('gaussian blur should have same result as opencv', async () => {
const img = getTestImage();
const options = {
borderType: BorderType.REFLECT,
size: 3,
sigmaX: 1,
sigmaY: 1
};
const blurred = gaussianBlur(img, options);
// const grey = convertColor(img, ImageKind.GREY);
// const greyBlurred = gaussianBlur(grey, options);
// console.log(greyBlurred.data);
const expected = await read('test/img/testGaussianBlur.png');
// write('gaussian.png', blurred);
expect(expected.data).toStrictEqual(blurred.data);
