Improvements to XML import

[birm]

This is about the xml import utility: https://github.com/camicroscope/caMicroscope/blob/master/apps/port/import.html

• From the xml, the line color under Annotation is a decimal representation of color, read this in
• Sometimes (always?) the xml document is supporting polyline, not polygon. This has confused users who have drawn lines and caMicroscope tries to "complete" the polygon
• Each XML Annotation group should be its own annotation object (toggleable independently)

Hi,
I want to try this issue.

Hi @birm,

I've been working on this issue for the past couple of days and have made the following improvements to address the issues raised in this ticket:

-Color Representation Fix:
The line color in the XML annotation is now correctly parsed from a decimal representation to a hexadecimal format.

-Handling Polyline vs. Polygon:
The XML import utility now differentiates between Polyline and polygons.
Now, if the region type is Polyline, it is correctly mapped to a LineString, while Polygon regions remain unchanged.

-Independent Annotation Groups:
Each XML annotation group is now processed as a separate annotation object.

-Bounding Box Implementation:
I added Bounding Box support to efficiently store the extent of each annotation.
The bounding box is calculated as the smallest enclosing rectangle around the annotation, using the min/max X and Y coordinates.

Please take a look and let me know if this aligns with the expected outcome, and if any changes are needed. If everything looks good, I can proceed with opening a PR.

The videos demonstrating the changes are below :

Wow, two people with interest in as many hours!

@chandrikarj at least at a glance, that looks better. Would you like to open a PR?
