Al momento è la migliore app per editare PDF

Decisamente la migliore app per modificare pdf, e le ho provate tutte. Fa tutto quello che serve, e lo fa bene. Consente di gestire anche funzioni avanzate come la creazione di collegamenti alle pagine interne del documento, per creare ipertesti pdf, il text reflow, tool grafici che funzionano perfettamente e numerose opzioni per gestire i file. La versione base gratuita è già ricchissima. Una favola.

Non riesco ad evidenziare - can’t underline

Alert: una stella solo per ricevere supporto, la all sembra fantastica
/One star is just to gather support, not a rating!

Quando clicco sulla barra degli strumenti e seleziono l’evidenziatore non accade nulla se provo a tracciare una linea: perché? È come se non scrivesse sul pdf.

When I select the “highlighter” on the toolbar and try to write on the document (pdf) nothing happening. I don’t see any color or line (underline or squiggly), only the free text tool works for me. Why?

Cancellate le sottolineature

Sarebbe un’app valida se non fosse che con l’aggiornamento si sono cancellate tutte le sottolineature dei documenti visionati questa estate, mandando all’aria ore di lavoro.
