ROIs

[omrd]

Is it possible to make all measurement (but not arrows) ROIs rotate through colors? For example, if I have 10 length measurements on a slice, it would be nice if the first one is blue, the second one is yellow, third is green, etc...

Right now Osirix does an OK job of it but would be nice if it can be implemented in Horos. It's the only thing preventing me from making the jump.

I tried.

(Japanese Version: '長さ' means 'Length')

(English Version: removing 'Length:')

But I managed some variables for changing color temporally.
After quiting 2D Viewer and re-running it, all ROI colors become same.

OsiriX MD memorize it?

[omrd]

That would be close to perfect if we can remove the label (I believe it's not in English in the last screenshot) all together and remove the black background all together. Is that possible?

[omrd]

It's on by default on OsiriX MD. It might be saved in preferences. It doesn't remember what the last color is between cases or restarts. Just that it randomly changes colors on each new study.

Feel free to talk about the best UI you believe now.
For, example.

• transparency (characters) ----- half-transparency? or non-transparency?
• the number of colors ----- 10? or 20? or more?
• color identity ----- random? or identical(always same color everytime you use the ROI you want to)?
• and so on

I will take them into consideration for the next time I modify my Horos(my friends call it 'HorliX').

I think what you have is good.
• Characters should always be opaque as should the lines.
• I think 10 colors is enough but that's up to you. Colors should be relatively bright. For example the blue and red that you have are a bit hard to read. Especially on reports.
• It would be good if colors rotate in the same order every time. First one is yellow, second is blue, etc...
• Labels can be done as the image I provided above (with or without backgrounds).

Hi, omrd.

I tried again!

How about this one?

[air-h-128k-il]

I choiced 10 colors which are less bright than the previous ones.
The color-order is green(default), topaz yellow, carrot orange, madonna blue......,when you are drawing.
But if you finish drawing the line, the all colors change.
The latest line you draw is always green in the above setting. The next latest one is topaz yellow. Next, carrot orange, Next, madonna blue.....
The color-order setting is freely determined because I add a variable and a function for ROI color management into ROI class.

I noticed the coding manners of the sources, which (maybe) rossetantonie and the osirix team wrote, in this modification. Their coding style is somewhat procedure-oriented. Easy to write, but hard to read.
Recent major coding style is, of course, object-oriented.
It is difficult to say which is better. But object-oriented coding style is suitable for open-source project.

By the way, you would like to apply your idea - ROI-color-rotation-UI - for ONLY staright line?
It is applicable in other ROI, for example AREA, as follows:

It is well shown also that the latest roi that you draw is almost green(default color).
mmm....carrot orange is difficult to read.....

[omrd]

All ROIs that measure anything (length, area, etc...). This is looking good but please don't forget removing the "Length:" label.

OK.
I have made the download page for this version of HorliX.

https://phazor.info/HorliX/?page_id=105

You can download and use it, if you like.
And I would like to hear your review.
