Topic: GetHTMLTextHeight bug?
Posted: 30 Jun 07 at 12:59PM

I am using v 5.22.0.119 of the library

For a single line of text (which appears fine is the resulting PDF doc), I get the correct result from GetWrappedTextHeight (5.8250666666667mm). However, for the same text and width, GetHTMLTextHeight returns 1239476.0000000

Is this a bug?

Hi!

What's your complete line of code in this case?
The HTML-functions are completely different from the normal pdf-functions.
I THINK the font height is relative to the value for "width" and the string-length.

Hi Ingo

It's nice to get such a quick reply

Here's the relevant lines of (C++) code:

double WidthBetweenMargins = 92.0;

double tmp1 = isedFunctions.GetHTMLTextHeight(WidthBetweenMargins, "Sample text which fits on a single line");

double tmp2 = isedFunctions.GetWrappedTextHeight(WidthBetweenMargins, "Sample text which fits on a single line");

Before this code there is the following:

isedFunctions.SetMeasurementUnits(1); // 1 = millimetres
isedFunctions.SetPageDimensions(112, 600);
isedFunctions.SetOrigin(1); // top left

Hi!
I don't think that the html-functions works like the other ones having to do with fonts and text. Try setmeasurementunits(0) (for pixels)... Is the returned value okay?

I tried SetMeasurementUnits(0) and the two calls still return completely different values.

I don't see why the html-functions should be any different - I thought that they were just taking the html formatting into consideration.

I am going to have a look at the source code to see if I can work out what's going on (unless Marian beats me to it ). I have the source code to v 3.78 - please tell me where to send one of the .pas files to prove this so that I can get the latest source.

Hi Colin!

EVERY help is welcome. Many shoulders are better than one ;-)
You can send the pas-file to Michel or me.
After this you'll get the password for the download-section.

Best regards,
Ingo

Hi Hopeful, Hi Ingo,
