Add support for custom fonts (for string below barcode)

[pk026]

How could use font family Bolonewt? I tried all of Times-Roman, Times-Italic, Times-Bold, Times-BoldItalic, Helvetica, Helvetica-Oblique, Helvetica-Bold, Helvetica-BoldOblique, Courier, Courier-Oblique, Courier-Bold, Courier-BoldOblique or Symbol. But it turns out that this is not something that we need. we have figured out that we need Bolonewt font family. But I am not able to find a way to use this new font family. Please help.

You need to refer to the font by its PostScript name.

These posts provide some hints for going about this:

Hey @terryburton that you so much for your quick reply.
Problem is not with font name, I am using PostScript name itself, still this font does not reflect.
Selected fonts reflects only if it is one of:
"Times-Roman, Times-Italic, Times-Bold, Times-BoldItalic, Helvetica, Helvetica-Oblique, Helvetica-Bold, Helvetica-BoldOblique, Courier, Courier-Oblique, Courier-Bold, Courier-BoldOblique or Symbol".
May be which these are the fonts which our current version provides.

You haven't provided any description of your configuration or workflow, or the steps that you have already taken to try to research the problem.

If the font is available to your PostScript VM (whatever this is as you haven't specified) then it will render. That's a feature of the RIP not BWIPP.

Hey @terryburton Following is python code which I am using to create.
import treepoem
from django.conf import settings
def create_bar_code(tl):
path = "{}/{}.PNG".format(settings.BAR_CODE_PATH, tl.bar_code)
shutil.rmtree(settings.BAR_CODE_PATH)
os.mkdir(settings.BAR_CODE_PATH)
image = treepoem.generate_barcode(
barcode_type='code39ext', # One of the BWIPP supported codes.
data= tl.bar_code + tl.otp,
options=dict(
includetext=True,
textxalign="justify",
textsize=11,
textfont="Cochin",
height=.7,
textyoffset=1,
inkspread=0.6,
)
)
return "{}/{}.PNG".format(settings.BAR_CODE_DIR, tl.bar_code), path

In this function when we pass value of textfont one of "Times-Roman, Times-Italic, Times-Bold, Times-BoldItalic, Helvetica, Helvetica-Oblique, Helvetica-Bold, Helvetica-BoldOblique, Courier, Courier-Oblique, Courier-Bold, Courier-BoldOblique or Symbol"
it reflects the change and respective font appears on barcode.
The comes when I try font family outside of this list like "Cochin", font on barcode appears is Helvetica.
What treepoem.generate_barcode() does is: It passes all the arguments to postscriptbarcode directly.

PLease let me know if I could provide more info on this.

What is the end-to-end workflow, i.e. in particular what is RIPping the resulting PostScript/EPS for rendition? E.g. GhostScript directly, GhostScript as a CUPS filter driver, Distiller, a PostScript printer.

Whatever that is must not have access to these fonts.

Thank you so much @terryburton to enlighten me with this flow thing. I could figure out that it was the font that was not installed properly. Thanks a ton dude.
