Can be used BT_DrawText or BT_DrawTextEx function.
Sample is in: ...\hmg\SAMPLES\BosTaurus\Demo3.prg.

Thank you, KDJ, exactly.

I am doing other tests with drawtext and found problems only creates the texts when initialized in the window onpaint if create in another window triggered by a button is also not generated the text follows the project example:

edk, if you do not use HPDFPRINT with some text of your HPDF_RotateText function the pdf file is not generated if you use apanes a line HPDF_RotateText (50, 80, "ABCxyz123", Nil, Nil, 90) will not generate the file. when to do the test delete the existing .pdf file

Corrected. I added font attributes, and colors.

By the way, I found a bug in the source h_HMG_HPDF.Prg
If you want to use the Bold and/or Italic attributes you need to add in h_HMG_HPDF.Prg at line #1812: cFnt := cFont (after "Otherwise"). Otherwise, cFnt variable for declared cFont: "Courier" and "Helvetica" is Nil value, which results in an error.
After the change, of course, you have to rebuild the HMG.

Please note:

Code: Select all

cFnt := cFont
instead of

Code: Select all

cFnt: = cFont
!
