DESCRIPTION

34       This is the "General Interface" for the PDL::IO::GD library, and is
35       actually several years old at this point (read: stable). If you're
36       feeling frisky, try the new OO interface described below.
37
38       The general version just provides several image IO utility functions
39       you can use with ndarray variables. It's deceptively useful, however.
40

FUNCTIONS

42   write_png
43         Signature: (byte img(x,y); byte lut(i,j); char* filename)
44
45       Writes a 2-d PDL variable out to a PNG file, using the supplied color
46       look-up-table ndarray (hereafter referred to as a LUT).
47
48       The LUT contains a line for each value 0-255 with a corresponding R, G,
49       and B value.
50
51       write_png does not process bad values.  It will set the bad-value flag
52       of all output ndarrays if the flag is set for any of the input
53       ndarrays.
54
55   write_png_ex
56         Signature: (img(x,y); lut(i,j); char* filename; int level)
57
58       Same as write_png(), except you can specify the compression level (0-9)
59       as the last argument.
60
61       write_png_ex does not process bad values.  It will set the bad-value
62       flag of all output ndarrays if the flag is set for any of the input
63       ndarrays.
64
65   write_true_png
66         Signature: (img(x,y,z); char* filename)
67
68       Writes an (x, y, z(3)) PDL variable out to a PNG file, using a true
69       color format.
70
71       This means a larger file on disk, but can contain more than 256 colors.
72
73       write_true_png does not process bad values.  It will set the bad-value
74       flag of all output ndarrays if the flag is set for any of the input
75       ndarrays.
76
77   write_true_png_ex
78         Signature: (img(x,y,z); char* filename; int level)
79
80       Same as write_true_png(), except you can specify the compression level
81       (0-9) as the last argument.
82
83       write_true_png_ex does not process bad values.  It will set the bad-
84       value flag of all output ndarrays if the flag is set for any of the
85       input ndarrays.
86
87   write_png_best
88       Like write_png(), but it assumes the best PNG compression (9).
89
90         write_png_best( $img(ndarray), $lut(ndarray), $filename )
91
92   write_true_png_best
93       Like write_true_png(), but it assumes the best PNG compression (9).
94
95         write_true_png_best( $img(ndarray), $filename )
96
97   load_lut( $filename )
98       Loads a color look up table from an ASCII file. returns an ndarray
99
100   read_png( $filename )
101       Reads a (palette) PNG image into a (new) PDL variable.
102
103   read_png_true( $filename )
104       Reads a true color PNG image into a (new) PDL variable.
105
106   read_png_lut( $filename )
107       Reads a color LUT from an already-existing palette PNG file.
108

110       Object Oriented interface to the GD image library.

SYNOPSIS

113        # Open an existing file:
114        #
115        my $gd = PDL::IO::GD->new( { filename => "test.png" } );
116
117        # Query the x and y sizes:
118        my $x = $gd->SX();
119        my $y = $gd->SY();
120
121        # Grab the PDL of the data:
122        my $pdl = $gd->to_pdl();
123
124        # Kill this thing:
125        $gd->DESTROY();
126
127        # Create a new object:
128        #
129        my $im = PDL::IO::GD->new( { x => 300, y => 300 } );
130
131        # Allocate some colors:
132        #
133        my $black = $im->ColorAllocate( 0, 0, 0 );
134        my $red = $im->ColorAllocate( 255, 0, 0 );
135        my $green = $im->ColorAllocate( 0, 255, 0 );
136        my $blue = $im->ColorAllocate( 0, 0, 255 );
137
138        # Draw a rectangle:
139        $im->Rectangle( 10, 10, 290, 290, $red );
140
141        # Add some text:
142        $im->String( gdFontGetLarge(), 20, 20, "Test Large Font!", $green );
143
144        # Write the output file:
145        $im->write_Png( "test2.png" );
146

DESCRIPTION

148       This is the Object-Oriented interface from PDL to the GD image library.
149
150       See <http://www.boutell.com/gd/> for more information on the GD library
151       and how it works.
152
153   IMPLEMENTATION NOTES
154       Surprisingly enough, this interface has nothing to do with the other
155       Perl->GD interface module, aka 'GD' (as in 'use GD;'). This is done
156       from scratch over the years.
157
158       Requires at least version 2.0.22 of the GD library, but it's only been
159       thoroughly tested with gd-2.0.33, so it would be best to use that. The
160       2.0.22 requirement has to do with a change in GD's font handling
161       functions, so if you don't use those, then don't worry about it.
162
163       I should also add, the statement about "thoroughly tested" above is
164       mostly a joke. This OO interface is very young, and it has barely been
165       tested at all, so if something breaks, email me and I'll get it fixed
166       ASAP (for me).
167
168       Functions that manipulate and query the image objects generally have a
169       'gdImage' prefix on the function names (ex: gdImageString()). I've
170       created aliases here for all of those member functions so you don't
171       have to keep typing 'gdImage' in your code, but the long version are in
172       there as well.
173

METHODS

175   new
176       Creates a new PDL::IO::GD object.
177
178       Accepts a hash describing how to create the object. Accepts a single
179       hash ( with curly braces ), an inline hash (the same, but without the
180       braces) or a single string interpreted as a filename. Thus the
181       following are all equivalent:
182
183        PDL::IO::GD->new( {filename => 'image.png'} );
184        PDL::IO::GD->new( filename => 'image.png' );
185        PDL::IO::GD->new( 'image.png' );
186
187       If the hash has:
188
189        pdl => $pdl_var (lut => $lut_ndarray)
190           Then a new GD is created from that PDL variable.
191
192        filename => $file
193           Then a new GD is created from the image file.
194
195        x => $num, y => $num
196           Then a new GD is created as a palette image, with size x, y
197
198        x => $num, y => $num, true_color => 1
199           Then a new GD is created as a true color image, with size x, y
200
201        data => $scalar (type => $typename)
202           Then a new GD is created from the file data stored in $scalar.
203           If no type is given, then it will try to guess the type of the data, but
204               this will not work for WBMP and gd image types. For those types, you
205               _must_ specify the type of the data, or the operation will fail.
206           Valid types are: 'jpg', 'png', 'gif', 'gd', 'gd2', 'wbmp'.
207
208       Example:
209
210        my $gd = PDL::IO::GD->new({ pdl => $pdl_var });
211
212        my $gd = PDL::IO::GD->new({ pdl => $pdl_var, lut => $lut_ndarray });
213
214        my $gd = PDL::IO::GD->new({ filename => "image.png" });
215
216        my $gd = PDL::IO::GD->new({ x => 100, y => 100 });
217
218        my $gd = PDL::IO::GD->new({ x => 100, y => 100, true_color => 1 });
219
220        my $gd = PDL::IO::GD->new({ data => $imageData });
221
222        my $gd = PDL::IO::GD->new({ data => $imageData, type => 'wbmp' });
223
224   to_pdl
225       When you're done playing with your GDImage and want an ndarray back,
226       use this function to return one.
227
228   apply_lut( $lut(ndarray) )
229       Does a $im->ColorAllocate() for and entire LUT ndarray at once.
230
231       The LUT ndarray format is the same as for the general interface above.
232

234       All of the docs below this point are auto-generated (not to mention the
235       actual code), so read with a grain of salt, and always check the main
236       GD documentation about how that function works and what it does.
