| Summary | 0004273: PDF Forms: Manual tracking in text fields isn't respected. | ||||
| Description | Bug 3282 is probably closely related. Adding manual tracking in PDF form fields does not get exported. I believe the proper way to do this is a 'n Tc' operator -- where n is a number and Tc is the postscript character spacing operator -- to DA (default appearance) key of the field. PDF Reference 1.6 Page 368 (I checked back as far as PDF 1.4) | ||||
| Steps To Reproduce | 1. Use the supplied file (it has tracking set to 20% on the field) 2. Export to PDF 1.4+ The value of the field DA is: '/Helv 18.00000 Tf 0.00000 0.00000 0.00000 rg', No mention of any form of character spacing changes. | ||||

In theory this could work, only problem is that the /DA entry of a text field is applied to the whole string defined be the /V key. So if you write the /DA entry this way /DA ( 0 0 1 rg 0.25 Tc 12 Tf ) it would apply the spacing to the whole string. And i guess you want to have that kerning adjustment only for specific glyph pairs. |

In my case no, I believe it should apply to the entire field (value of V key). As AcroFrom strings are being supplied by the user, applying custom kerning or tracking adjustments to specific glyph pairs doesn't seem realistic (outside of embedding the font again with a custom metrics file). Related to that though, I can see how it might be nice to have the exact text/styling shown in Scribus field -- things like bolded or different colour words in the string -- to be preserved in the PDF. All annotations (Acroform widgets are considered annotations) can have an appearance dictionary (AP key) associated with then (since PDF 1.2). By converting the field appearance to a Form XObject stream the exact styling could be preserved until the field was edited: At which point the DA key would rule and be used to style the entire string of new input (except when the RV key is present and CSS attributes override it). |
