Image to ZPL Graphic Field with ZebrafyImage

Convert image bytes into a complete ZPL string and save to file:

from zebrafy import ZebrafyImage

with open("source.png", "rb") as image:
    zpl_string = ZebrafyImage(image.read()).to_zpl()

with open("output.zpl", "w") as zpl:
    zpl.write(zpl_string)

Example usage with optional parameters:

from zebrafy import ZebrafyImage

with open("source.png", "rb") as image:
    zpl_string = ZebrafyImage(
        image.read(),
        format="Z64",
        invert=True,
        dither=False,
        threshold=128,
        width=720,
        height=1280,
        pos_x=100,
        pos_y=100,
        rotation=90,
        string_line_break=80,
        complete_zpl=True,
    ).to_zpl()

with open("output.zpl", "w") as zpl:
    zpl.write(zpl_string)

Alternatively, ZebrafyImage also accepts PIL Image as the image parameter instead of image bytes:

from PIL import Image
from zebrafy import ZebrafyImage

pil_image = Image.new(mode="RGB", size=(100, 100))
zpl_string = ZebrafyImage(pil_image).to_zpl()

with open("output.zpl", "w") as zpl:
    zpl.write(zpl_string)

PDF to ZPL Graphic Field with ZebrafyPDF

Convert PDF bytes into a complete ZPL string and save to file:

from zebrafy import ZebrafyPDF

with open("source.pdf", "rb") as pdf:
    zpl_string = ZebrafyPDF(pdf.read()).to_zpl()

with open("output.zpl", "w") as zpl:
    zpl.write(zpl_string)

ZebrafyPDF conversion supports the same optional parameters as ZebrafyImage conversion, with the addition of the split_pages parameter to split the PDF pages:

from zebrafy import ZebrafyPDF

with open("source.pdf", "rb") as pdf:
    zpl_string = ZebrafyPDF(
        pdf.read(),
        format="Z64",
        invert=True,
        dither=False,
        threshold=128,
        dpi=203,
        width=720,
        height=1280,
        pos_x=100,
        pos_y=100,
        rotation=90,
        string_line_break=80,
        complete_zpl=True,
        split_pages=True,
    ).to_zpl()

with open("output.zpl", "w") as zpl:
    zpl.write(zpl_string)

ZPL to PDF or Images with ZebrafyZPL

Convert all graphic fields from a valid ZPL file to PIL Images and save to image files:

from zebrafy import ZebrafyZPL

with open("source.zpl", "r") as zpl:
    pil_images = ZebrafyZPL(zpl.read()).to_images()
    for count, pil_image in enumerate(pil_images):
        pil_image.save(f"output_{count}.png", "PNG")

Convert all graphic fields from a valid ZPL file to PDF bytes and save to PDF file:

from zebrafy import ZebrafyZPL

with open("source.zpl", "r") as zpl:
    pdf_bytes = ZebrafyZPL(zpl.read()).to_pdf()

with open("output.pdf", "wb") as pdf:
    pdf.write(pdf_bytes)
