Feature Request: Mask painting precision assistance

Problem:

Currently, when mask is set to true, we have a blank canvas added to the right side of the input (or preview) image.

We then paint the areas we wish to mask, these masked areas are applied to the input image using the selected controlnet.

One issue with this is that it can be quite difficult to work out whether we are precisely masking the areas of the input image as intended, we have to kind of roughly judge, and if the desired masking area is small or needs to be precise this can be quite difficult.

Proposed solution:

It would be very helpful if one of the following could be implemented:

Either

a) Drawing a mask area in the mask image window also draws the painted mask area, @ low/medium opacity over the input image to the left.

or (preferable)

b) The input image can be shown/overlaid (with a toggle) in the mask image window, @ low/medium opacity, and be painted over, without this overlaid image interfering with or influencing the generated mask.

Commencez par localiser le code UI de l’image d’entrée ou d’aperçu et de la fenêtre de l’image de masque, puis suivez la manière dont les zones de masque peintes sont appliquées via le ControlNet sélectionné. Comparez les deux approches d’overlay proposées et définissez un overlay d’entrée activable, avec une opacité faible ou moyenne, qui ne modifie pas le masque généré ; le travail est terminé lorsqu’un alignement précis est visible tout en conservant un comportement inchangé du masquage.
