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. Best regards, Ingo |

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 Colin

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? Best regards, Ingo |

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.

Ingo 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 Colin

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 |

This turned out to NOT be a bug. I am using the dll with a Visual C++ application and I have to create my own set of header files. I had mistakenly declared GetHTMLTextHeight as returning an int instead of a double
