Regarding HPDFURLLINK command

Post by Paramvir »

Hi

While generating PDF, the command
HPDFURLLINK creates a text link that has border around it. I use this syntax:

@200, 20 HPDFURLLINK xvariable to "URL link" color { 255, 20, 147 } FONT "COURIER-BOLD" SIZE 8

This creates a border around the text. I am not sure how to create a borderless link. Any suggestions ?
Thank you all.

I think it is the feature of LibHaru PDF library.
East or West HMG is the Best.
South or North HMG is worth.
...the possibilities are endless.

Thank you Rathi ji for the reply. I took this command and syntax from the HMG_HPDF_doc.PDF which I think has been created by you and this PDF file is given in HMG3.4.4\SAMPLES\HPDF\HMG_HPDF.

I want to create a borderless text link but this command doesn't say anything about it. Perhaps you can help.

Replace the _HMG_HPDF_SetURLLink function in the h_HMG_HPDF.Prg file with the one below, then rebuild the HMG.

Code: Select all

Thank you Edk for the generous help and sharing your code. I would like to try it although it seems a bit daunting for a person like me with limited programming knowledge. Thank you once again.

Nice Edk. Have you tried to update to the latest libharupdf? Because it has the feature of Unicode/UTF-8

It is a long pending one to have a native support for unicode pdf.
East or West HMG is the Best.
South or North HMG is worth.
...the possibilities are endless.
