Hi,

i use RenderPageToFile with Delpjhi 10.4 to get a bitmap of a PDF page.

In a Windows App all works fine, but in the same App compiled as Android App any fields or textblocks are not visible or wrong attributes:

Arial : is visible

Arial bold : is not visible

Arial kursiv : is visible but not bold

Time New Roman : is not visible

Time New Roman bold : is not visible

Time New Roman kursiv : is not visible

Courier New : is visible

Courier New bold : is visible but not bold

Courier New kursiv: is visible but not kursiv

What can i do to RenderPageToFile correct to a bitmap?

Ciao

Stefan

The fonts won't be embedded?

Are the fonts available on the device?

What sometimes helps are functions like:

>> NormalizePage,

>> CombineContentStreams,

(TransformFile),

(BalancePageTree).

All you wrote has no effect :-(

The fonts are added to PDF, if i show it in Android Chrome all is correct!

Now i tried

ViewPrintQP.RenderPageToString(120,1,9);

to get the page as HTML, in Windows this works fine, but in Android the result is a TFoxitQPLBytearray and i can't findout how to declare this (unknown type TFoxitQPLBytearray )

Ciao

Sorry.

Don't know how to step into your issue.

Perhaps here's still another one able to dig into your issue.

1. I know nothing about Android development.

2. Opening a PDF and showing fonts correctly in a specific environment (eg 'Android Chrome') is not sufficient to prove that the fonts are embedded; they may be substituted somehow, or found by the app elsewhere. Open the problem PDF in Acrobat and press control-D to show the embedded fonts and whether they are subsetted.

3. If they are not embedded, or not in a way that your application can use them on Android, then sorry, I also cannot help further for this environment, but I hope this may help you in some way.

First check your PDF has embedded fonts, check Android's support for these fonts, update your PDF rendering library, try altering RenderPageToFile settings, debug for font loading/rendering issues and explore alternative PDF rendering methods.
