Small image can't scale

[AnswerZhao]

When the loaded photo is too small , the image can't scale by touching.

I confirm.

Scale and translation gesture are activated.

• @vellrya @AnswerZhao You can set a min-max scale. Default min is 0.7, default max is 3.

app:ci_max_scale="1f"

cropView.configureImage()
  .setMinScale(minScale)
  .setMaxScale(maxScale)
  .apply();

Try to decrease minScale / increase maxScale

@polyak01 It can't works.

@AnswerZhao do you try to setMinScale(0.1f)?

[AnswerZhao]

@polyak01
float scaleFactor = detector.getScaleFactor(); float newScale = matrixUtils.getScaleX(imageMatrix) * scaleFactor;
When the photo is too small, the newScale value is too lager than the maxScale.(70*70Px, the newScale is 25), so i think the scale value is not perfect. I change the method isValidScal() to resolve it finally.

@polyak01
I set MaxScale to 9f (minimum value at which it start working with my (409*103) picture) and MinScale to 0f.
It works, but it works strange. Until I set the frame with the same aspect ratio as the picture itself, I can not reduce the image. In addition, scale gestures work only outside the crop area.

@vellrya 9 is not work for everything, you can try a 43*43 picture.

Okay. I decided for myself this problem. I completely removed Min and Maxscale and did this:

cropView.configureOverlay()
                .setAspectRatio(AspectRatio.IMG_SRC)
                .apply()

Now I can correctly move and scale small pictures. (http://dropmefiles.com/KQByj)
It remains only to wait for the ability to rotate pictures in this library)

@AnswerZhao Did you solved the problem?

[AnswerZhao]

@polyak01 Yep. You can change the implement of the method isValidScal() ,or increase the maxScale, or remove the limits of maxScale.
