just write text in different color, font, and size to a existing pdf and save the result

API

Example:

pdf = require 'pdf-write-page'
pdf {in:'test_unmodified.pdf', out:'test_modified.pdf', pageNumber:0}
.write 10, 0, 'A'
.write 10, 14, 'B'
.cfg {size:60}
.write 10, 28, 'C'
.restoreCfg()
.write 100, 100, 'D'
.end()

end also saves to out path.

page offset is bottom, left (x = 0, y = 0)

.write()

writes some text

.write(x, y, text)

.image()

add an image (jpg, pdf, tiff) to the pdf

Optionally there's a 4th parameter which is an options object. The object may have the following properties, to modify the default image placement behaviour:

• index - for multi-page image formats (tiff, PDF), index determines the page to show. Default is the first image in the collection.
• transformation - transformation method. Can be either a array or an object. If it is a array, then transformation will be a 6 numbers matrix, allowing you to scale, rotate, translate or whatnot. If it is an object, than it is meant for defining an image fitting behaviour. You will define bounding with/height, and the module will scale the image in accordance. the object may have the following attributes:
  • width - required, width of bounding box
  • height - required, height of bounding box
  • proportional - boolean, should the fit method maintain the image proportions?
  • fit - either always or overflow. If always Fit may always happen scaling up or down. If overflow fit will scale only if the image dimensions overflow the box.

example:

.image(x, y, path, opts)

.page()

set the current page that is modified Pagecount starts as 0

exmaple:

    .page(1) # update page 2

.cfg()

options:

    fontPath   : ''
    size       : 14
    colorspace : 'gray'
    color      : 0x00
