I would like to propose a new Magic Wand Selection method, as I find the current Magic Wand Selection action very inefficient:
1. While holding down a modifier key, clicking on several positions collects the colors of the clicked pixels in a ColorList. Then the lifting-up of the modifier key ends the collecting of colors.
2. Then, when clicking on any pixel position, does not use only this clicked pixel's color for the Magic Wand processing but all the colors previously collected. This would be much more efficient.
It could also be combined with an option where in step 2 not a single click starts the Magic Wand process but a brush-painting mouse tool is dragged and is effective only on those pixels under the dragged brush tool which correspond to the previously selected colors.
What do you think? |

Hi
We have implemented a new method that allows selection using the ChromaKey algorithm. You can email us to test it, if you like.

Yes, that would be cool, especially if the cursor enlarged to match the hotspot size. I'll look into this for a later update.

Hi Nigel,
I will try Chromakey tomorrow.
I once made some experiments. For example:
While still holding down a modifier key, each clicking increases the tolerance. In this way, you could expand the selection area by just clicking repeatedly on the same place with the CTRL key pressed. Then, when lifting the CTRL key the tolerance goes back to standard value and you can play the same game on a place nearby which is not already selected. This works pretty well.
The main problem with the current MagicWand selection: No matter how exact the user tries to be there always remain small hotspots of unselected space between the existing selections. These unselected hotspots are very difficult to hit, so it is difficult to create a contiguous area of selection. So maybe a variable hotspot size could be something to try.
Just the other day an idea similar to your chromakey thing came to my mind and it's funny that you just mention it. |

Hi Peter
We have considered making another magic wand mode that grabs more colors, in a similar way to ChromaKey:
https://www.imageen.com/help/TImageEnProc.RemoveChromaKey.html
(If you try the ChromaKey demo, you will see that it can use all colors in a selection).
The hard bit is adding it in a way that is practical for users to access. I like the idea of being able to paint an area for removal.
In the meantime, have you tried increasing the tolerance?
