Tilman Hausherr commented on PDFBOX-2518:
-----------------------------------------
I've had another look at this, by using a font {{ZX______.PFB}} I found on
github. It can be tested by calling {{new PDType1Font(doc, is)}} or by using
the HelloWorldType1 example. The "bind" problem is easy to handle by adding it
to {{readDef()}} however there's more... it then fails in this line:
{code:java}
/Blend 3 dict dup begin
/FontBBox{{-55 -112 -286 -275 }{-261 -261 -261 -262 }{424 1156 1389 1981 }{811
915 839 970 }}def
/Private 14 dict def
end def
{code}
I suspected this is a nested dictionay and asked ChatGPT to reformat and here's
what this is:
{code:java}
/Blend 3 dict dup begin
/FontBBox {
{-55 -112 -286 -275 }
{-261 -261 -261 -262 }
{424 1156 1389 1981 }
{811 915 839 970 }
} def
/Private 14 dict def
end def
{code}
So yes... and here's the whole PostScript reformatted:
{code:java}

I was wondering what happens after "/shareddict" and asked ChatGPT:
{quote}h3. Summary of what the program is doing:
* *Managing shared font data:* The program checks whether a shared font
dictionary exists ({{{}/shareddict{}}}) and updates the current font data
accordingly.
* *Blending logic:* It calculates and applies font blending transformations
using vectors like {{WeightVector}} and {{{}$Blend{}}}.
* *Font creation and encoding:* The program processes font data to create or
manipulate fonts, blending them if necessary, and then applying the new font
definitions with updated attributes like encoding and scale.
* *Design vector normalization:* It adjusts the design vectors to normalize
the scaling of the font.
This section seems to be part of a larger font-handling routine that allows for
flexible manipulation of font attributes, possibly for creating variable fonts
or custom font blends.

So... uh, I doubt we can ever handle this file.
