Need help using the line tool

[ufuk23]

I can't use the line tool, it exists in the src tools folder but cannot be used. It doesn't exist in the latest min.js file released. I tried to generate it from the source code typing "npm run build" command, but it did not work so I could not build it for the latest selector min.js file. What is the best practice to use the line tool without suffering?

The line tool didn't exist yet when the last release was publishe. I think it's good to go, though. I'll to see if I can test (and create a new release) soon-ish. The build should work however. (Just tested and there's nothing broken with it in principle.)

What problem are your seeing when you do npm run build? Did you run npm install before? You'll definitely also need up-to-date versions of node and npm. I just tested with node 16.16 and npm 8.15.

I get some runtime errors trying to build selector project. Is it the right way to use commands 'npm install' and 'npm run build' for this project as well?

Then I try another way and put the line folder to the annotorious project and build it with npm. It seems it works with this way but some issues exist. Now I can create a line but cannot update or move it, it doesn't allow me to select :) I am confused and dont know how to do it

[rsimon]

Yes, exactly.

• Clone the repository
• npm install
• npm run build

Output JS should be in the /dist folder.

Hm... I'll test. It might be that the line tool is indeed still unfinished at the moment.

Hi, thank you for your interest 👍 I try it on another PC, (here are the versions npm v9.1.2 node v18.12.1 and the Error)

That seems like a compilation error, but I can build the other annotorious projects similarly.

• When do you plan to release the new version of the selector-pack that includes the line tool?
• Would you mind sending me the latest annotorious-selector-pack.min.js file that includes the line tool you have?

By the way, when I try to build the "annotorious-openseadragon" project, I think I get some issues because of an outdated code. It tells me the error is about "pointInLine" like below and I realize it doesn't exist in the annotorious-openseadragon project. Then I replace it with the latest "annotorious" source code and it can be build and work now. I mean line tool works when I put it in the tools folder and add some line for ToolRegistry.js file. I think it works using in the selector-pack without changing the "annotorious" project source code.

WARNING in ./src/AnnotationStore.js 117:11-22
export 'pointInLine' (imported as 'pointInLine') was not found in '@recogito/annotorious/src/util/Geom2D' (possible exports: pointInCircle, pointInEllipse, pointInPolygon, polygonArea, polygonInPolygon, svgPathToPolygons)

hi @rsimon
is the line tool ready for use ? if not can you help me implement this feature

[rsimon]

The line tool should be available in the latest source. If you build the selector pack yourself (npm install -> npm run build), the tool should be available. Did you try that?

[akshayp0]

i tried with the latest source but i was not able to draw line using annotorious-openseadragon, i can select line tool & select points for drawing the line but the line doesn't get saved

[rsimon]

Does saving work for other shapes? Per default, annotations that don't have any content (=a comment or a tag) don't get saved. If you want to be able to save "empty" annotations, you need to initialize with the allowEmpty init option. (See here: https://recogito.github.io/annotorious/api-docs/annotorious/#initialization). Does this change anything?

[spoorthym1999]

I was able to draw the line but the line wasn't selectable , rotatable and extendable as in other shapes.

[rsimon]

Hm, the latest version of AnnotoriousOSD (2.7.10) should support selecting of line shapes. (2.7.9 didn't.) So, at least, the popup box should open. But, yes, it's work in progress, and a 3rd party contribution. I'm not sure if editing functionality has been added yet. (And don't currently have the time to do this myself.)

[akshayp0]

No, the latest version doesn't support selecting line shape. AnnotoriousOSD throws Unsupported SVG shape type: line . There is no line support in the source code https://github.com/recogito/annotorious-openseadragon/blob/main/src/gigapixel/index.js

[rsimon]

Oh, yes - you are right. It lacks support for line shapes in Gigapixel mode. Should work in normal mode I think. How big is your image?

[akshayp0]

it is a tiled deep zoomable image
