Clear highlighted text or detect if already highlighted

[AndreaCCS]

I need to be able programatically clear the highlighted text. It could also be useful to know if the characters are highlighted (e.g characters 2 - 10 on page 6 of a doc). The reason I need this is I am programatically highlighting some characters when they click on the text I retrieve from the database, if they had already clicked the same text before the highlight gets darker and darker until it is black!

I am using this code to highlight the characters
object DataOut = 0;
object[] vArr = new object[3];
vArr[0] = 1;
vArr[1] = 10;
vArr[2] = 32768; //Green
object DataIn = vArr;

axCoPDFXCview1.DoVerb("Documents[0].Pages[0].Text", "Highlight", DataIn, out DataOut, 0);

Hi, AndreaCCS.

In your case you may:

1. use new feature for create annotation with unique ID(name):
object DataOut = 0;
object[] vArr = new object[5];
vArr[0] = 1;
vArr[1] = 10;
vArr[2] = 32768; //Green
vArr[3] = 1.0; //opacity
vArr[4] = "NewAnnotID";
object DataIn = vArr;
...
axCoPDFXCview1.DoVerb("Documents[0].Pages[0].Text", "Highlight", DataIn, out DataOut, 0);
- this feature will be added into the new build (53, upcoming).

2. use java-script for deleting of the added annotation:
string script = "var a = this.getAnnot(0, "NewAnnotID"); if (a != null) { a.destroy(); };";
axCoPDFXCview1.RunJavaScript(script, null, -1, 0);

Best
Regards.

When is version 53 being released?

[Vasyl - PDF-XChange]

Build 53 is already released.

[AndreaCCS]

Yes have downloaded and installed - the confusion is the build version on the product page says the version is 2.052!

[Stefan - PDF-XChange]

The build numbers are now updated - apologies for the confusion.
