Christoph Heuel 0ef2951c7e Introduce new direct_image
* The direct_image method prints directly from the PIL image object
* The image should be converted to 1 bit before
* The method was derived from png2escpos (https://github.com/twg/png2escpos)
2015-06-10 03:21:52 +02:00
Christoph Heuel dd228c9fda Add text wrapping
* The base class supports to give columns, how much it should wrapped.
* This is meant for longer text.
* The special instances need to initialize the super class with the
* columns
2015-06-04 14:11:11 +02:00
Christoph Heuel 7da2e32e3c Integer is needed, not float
* The size of the image can only be integer, not float.
  Using round to convert it back

Christoph Heuel b99c076bae Fix for string operation
* With Python version 3 data and text are treated different. Convert the

Nathan Bookham 6fdea1234d Adjusted QR error correction
Maxed out the error correction on QR code generation for vastly improved recognition. The trade-off is that the amount of bytes that can be stored are reduced.

Stephan Sokolow 5a99c73e7a Start on a command-line interface to the library (still hard-codes USB ID)
(...and still needs better documentation)
2014-08-15 20:20:02 -04:00
Stephan Sokolow 64c36a74ed Allow bandsize to be varied in fullimage() 2014-08-15 20:17:35 -04:00
Stephan Sokolow 2a8f852c68 Ensure QR codes have a border large enough for successful scan
(The QR code spec requires a border at least 4*box_size thick but we can't
 just set border=16 because that results in a QR code more than 255px tall
 and I'm not yet ready to use fullimage() as a backend for it)

Stephan Sokolow b6216403c4 Apply the cash drawer fix detailed in Issue 10 on the Google Code repo.

Stephan Sokolow 6e72d2778d Allow bypassing the resizing and height-cropping steps in fullimage() 2014-05-22 01:08:58 -04:00
Stephan Sokolow 5b1e6348e5 Accept "CODABAR" as an alias for "NW7" in barcode() 2014-05-22 00:55:09 -04:00
Stephan Sokolow 9885deaa59 Make BarcodeSizeError and BarcodeTypeError display the erroneous value
(MUCH more helpful for debugging)
2014-05-22 00:55:09 -04:00
Stephan Sokolow b5f68f6895 Actually use the barcode height and width parameters
(And reverse their order in the method signature so corrections to the
range checks don't break existing code)
2014-05-22 00:55:09 -04:00
Stephan Sokolow ac640785cc Make the structure of the ESC/POS commands less opaque
(The commands are intended to be readable by people who grew up with ANSI
 escape codes so represent them that way in the code)
