Single pixel diffs are not ignored #34
Description
Using looks-same v3.3.0.
Note that the reference image was generated using WebGL on a Macbook Pro 2015, whereas the generated image is generated using a docker image running Ubuntu with osmesa.
looks-same configuration:
await looksSameAsync(actual, expected,
{
tolerance: tolerance,
pixelRatio: self._getDPI(), // set to device DPI
ignoreAntialiasing: true,
ignoreCaret: true
});
await looksSame.createDiffAsync({
reference: this._getReferenceFilePath(),
current: this.getActualFilePath(),
diff: this._getDiffFilePath(),
highlightColor: '#ff00ff',
tolerance: tolerance,
pixelRatio: self._getDPI(),
ignoreAntialiasing: true,
ignoreCaret: true
});

generated image:
diff:
The lower left pixel of the triangle is showing up as different, and the test is failing due to this.

Hi. You can ignore these single-pixel diff in your own.
I left a comment in the next PR on how to get count of different pixels: #33 (comment)
You can implement custom check with these "differentPixels" and "totalPixels", returned with specified "createDiff: true"
Does it solve your problem?
