Hi there,

Thank you for your feedback.

This behavior seems unusual as it should not be converting it to black and white. Besides, the black and white conversion is unusable.

I have sent this to our developpers who will look into a fix as this document may contain very specific and rare attributes which are causing this.
I'll let you know when I have more news.

How can I set license for a code Visual Basic 2017?
My code:
Dim wPdfReducer As New GdPicturePDFReducer
wPdfReducer.ProcessDocument("C:\Provisor\Boleto_Teste_Original.pdf", "C:\Provisor\compressedreducer7.pdf")

This code work very well, by show error message stop (gdprocessing is required ...)

Hi Marsenne,

I have responded in both your tickets. If you are getting any other issues do not hesitate to let us know and we'll assist you in one centralized place if this is only concerning a single issue.

As mentioned, this is what you need for license registration:

Thanks, I thought that PDF was incompressible by default. Especially when it was made from Word document directly. Several MBs!
