# PDF_EPS class from Valentin Schmidt ported to ruby by Thiago Jackiw (tjackiw@gmail.com)
|
|
||||||
# working for Mingle LLC (www.mingle.com)
|
|
||||||
# Release Date: July 13th, 2006
|
|
||||||
#
|
|
||||||
# Description
|
|
||||||
#
|
|
||||||
# This script allows to embed vector-based Adobe Illustrator (AI) or AI-compatible EPS files.
|
|
||||||
# Only vector drawing is supported, not text or bitmap. Although the script was successfully
|
|
||||||
# tested with various AI format versions, best results are probably achieved with files that
|
|
||||||
# were exported in the AI3 format (tested with Illustrator CS2, Freehand MX and Photoshop CS2).
|
|
||||||
#
|
|
||||||
# ImageEps(string file, float x, float y [, float w [, float h [, string link [, boolean useBoundingBox]]]])
|
|
||||||
#
|
|
||||||
# Same parameters as for regular FPDF::Image() method, with an additional one:
|
|
||||||
#
|
|
||||||
# useBoundingBox: specifies whether to position the bounding box (true) or the complete canvas (false)
|
|
||||||
# at location (x,y). Default value is true.
|
|
||||||
#
|
|
||||||
# First added to the Ruby FPDF distribution in 1.53c
|
|
||||||
#
|
|
||||||
# Usage is as follows:
|
|
||||||
#
|
|
||||||
# require 'fpdf'
|
|
||||||
# require 'fpdf_eps'
|
|
||||||
# pdf = FPDF.new
|
|
||||||
# pdf.extend(PDF_EPS)
|
|
||||||
# pdf.ImageEps(...)
|
|
||||||
#
|
|
||||||
# This allows it to be combined with other extensions, such as the bookmark
|
|
||||||
# module.
