  4. Text annotation HTML events take too long

Text annotation HTML events take too long

Hello! Im working with Angular 10, and .netcore bakend, and I'm facing issues about performance with the module of PdfViewer when annotations textfree is maked.

Problem: When typing (on new or existing text annotation), the event keydown take too long and has warnings of [violation] in chrome devTools with verbose mode (as the following image shows)
image

The above warnings appears when user is typing in a text annotation in PdfViewer.

Im facing the same issue in the demo page of angular https://ej2.syncfusion.com/angular/demos/#/material/pdfviewer/default, not with the same event but showing other warnings and sometimes it take a while to finish and showing what I typed.

Thanks in advance.

Hi Luis, 

We are currently using the setTimeout function for updating the height of the input free text element, So we suspect that the issue is due to usage of time out in this event, so we will analyze further on this and update the details on 27th November 2020.

Hi Team,  

Sorry for the inconvenience caused.   

The fix for the reported issue will not be included in our volume 4 release. In our PDF Viewer, we have used setTimeOut function in events, so it takes time to perform the actions. We will improve the performance for the action of events, and it will be included in our volume 1 SP release which is expected to be rolled out in the end of January 2021.

Akshaya
