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 piddle variables. It's deceptively useful, however.

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

SYNOPSIS

112        # Open an existing file:
113        #
114        my $gd = PDL::IO::GD->new( { filename => "test.png" } );
115
116        # Query the x and y sizes:

122
123        # Kill this thing:
124        $gd->DESTROY();
125
126        # Create a new object:
127        #
128        my $im = PDL::IO::GD->new( { x => 300, y => 300 } );
129
130        # Allocate some colors:
131        #
132        my $black = $im->ColorAllocate( 0, 0, 0 );
133        my $red = $im->ColorAllocate( 255, 0, 0 );
134        my $green = $im->ColorAllocate( 0, 255, 0 );
135        my $blue = $im->ColorAllocate( 0, 0, 255 );
136
137        # Draw a rectangle:
138        $im->Rectangle( 10, 10, 290, 290, $red );
139
140        # Add some text:
141        $im->String( gdFontGetLarge(), 20, 20, "Test Large Font!", $green );
142
143        # Write the output file:
144        $im->write_Png( "test2.png" );
145

DESCRIPTION

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

METHODS

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

234       actual code), so read with a grain of salt, and always check the main
