Convert an image to a ZPL label parsable by a zebra printer

Zplify - Image to ZPL converter

Convert PNG, JPG, or any supported image type to ZPL for a Zebra printer.

Prints the ZPL directly to the console unless -o or --output is provided, then it will save the zpl to the target file.

Options

The full list of available options are as follows:

-l --length             Set the length of the label in pixels. 1200px is default.  
-w --width              Set the width of the label in pixels. 800px is default.  
-o --output             Set the output path. If omitted, the label will output to the terminal 
-i --interpolation-mode Set the interpolation mode. 1-7, default is 7
                        1=Low, 2=High, 3=Bilinear, 4=Bicubic 5=NearestNeighbor 6=HighQualityBilinear 7=HighQualityBicubic
-h --help               Display this message  

Example usage

# send directly to zebra printer
./zplify ./path/to/file.png | lpr

# save to output.zpl and resize.
./zplify ./path/to/file.png -o output.zpl -l 1800 -w 800

# pipe input from URL, convert to ZPL and send to printer
wget -O www.example.com/label.png | ./zplify | lpr -P printer_name

zplify's Issues

Github Project - Add Topics

It would be nice if you could assign some topics to your project. 😄

Here are a few suggestions:

The bitmap is not redrawn on rotate

In function ScaleAndRotateBitmap the bitmap needs to be redrawn before returning it

g.DrawImage(bitmap, 0, 0);

zplify/Zplify/ZplImageConverter.cs

Line 136 in 4010c55

g.InterpolationMode = InterpolationMode.Bicubic;

Converting UPS Labels

Hi Nelson,
Have you tried converting UPS labels (either .gif or .png) using this code? It produces a ZPL output but it doesn't appear to be valid. Trying to render it on laberly.com returns the following:

"ERROR: you requested the 1st label, but the specified ZPL doesn't generate any labels"
