Uncaught DOMException: Failed to execute 'createPattern' on 'CanvasRenderingContext2D': The canvas width is 0. about timeline-view HOT 10 OPEN

It's a valid issue, if the tool finds no output, it shouldn't fail.

The resolution for now is:

Put the "profiling": "timeline" in the app/package.json instead the package.json.

from timeline-view.

Could you please tell which of the version is running fine? I have tested 0.0.5 & 0.0.6. None of them working. getting the same error

Uncaught DOMException: Failed to execute 'createPattern' on 'CanvasRenderingContext2D': The canvas width is 0.

It has been opened since July. is it actively maintained or are there any alternate packages?

Sorry, my fault. I've write the line "profiling": "timeline" in the wrong package.json.

You can change pixelPerMs to 1 it should work then.

I get the same error message in the browser, but the output seems to be in the html page.

The problem is reproducible with NS 3.3:

1. tns create TimelineTest --template ng
2. cd TimelineTest/
3. vi app/package.json and add "profiling": "timeline"
4. tns run android | timeline-view
5. Ctrl-C after the app has started and open the file in the browser (tested with latest Chrome, FF and Safari)

When running the app, I can see many "Timeline: ..." statements and looking at the html, the variable timeline seems to contain the output.

The issue is caused by: https://github.com/PanayotCankov/timeline-view/blob/master/chart.ts#L257
for really small values width is rounded to 0 which causes the error.

I'm also facing the same issue

from timeline-view.

@PanayotCankov I see all the outputs in my html page, however, I still get the same error Failed to execute 'createPattern' on 'CanvasRenderingContext2D': The canvas width is 0.

this only happens in some apps, while it works fine in other apps I tried it on.

I tried to change pixelPerMs but still no luck, any ideas?
