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.
40

FUNCTIONS

42   write_png
43         Signature: (byte img(x,y); byte lut(i,j); char* filename)
44
45       Writes a 2-d PDL varable 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 arguement.
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 varable 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 arguement.
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( $img(piddle), $lut(piddle), $filename )
87       Like write_png(), but it assumes the best PNG compression (9).
88
89   write_true_png_best( $img(piddle), $filename )
90       Like write_true_png(), but it assumes the best PNG compression (9).
91
92   load_lut( $filename )
93       Loads a color look up table from an ASCII file. returns a piddle
94
95   read_png( $filename )
96       Reads a (palette) PNG image into a (new) PDL variable.
97
98   read_png_true( $filename )
99       Reads a true color PNG image into a (new) PDL variable.
100
101   my $lut = read_png_lut( $filename )
102       Reads a color LUT from an already-existing palette PNG file.
103

OO INTERFACE

105       Object Oriented interface to the GD image library.

SYNOPSIS

108        # Open an existing file:
109        #
110        my $gd = PDL::IO::GD->new( { filename => "test.png" } );
111
112        # Query the x and y sizes:

114        my $y = $gd->SY();
115

117        my $pdl = $gd->to_pdl();
118
119        # Kill this thing:

121
122        # Create a new object:
123        #
124        my $im = PDL::IO::GD->new( { x => 300, y => 300 } );
125
126        # Allocate some colors:
127        #
128        my $black = $im->ColorAllocate( 0, 0, 0 );
129        my $red = $im->ColorAllocate( 255, 0, 0 );
130        my $green = $im->ColorAllocate( 0, 255, 0 );
131        my $blue = $im->ColorAllocate( 0, 0, 255 );
132
133        # Draw a rectangle:
134        $im->Rectangle( 10, 10, 290, 290, $red );
135
136        # Add some text:
137        $im->String( gdFontGetLarge(), 20, 20, "Test Large Font!", $green );
138
139        # Write the output file:
140        $im->write_Png( "test2.png" );
141

DESCRIPTION

143       This is the Object-Oriented interface from PDL to the GD image library.
144
145       See <http://www.boutell.com/gd/> for more information on the GD library
146       and how it works.
147
148   IMPLEMENTATION NOTES
149       Surprisingly enough, this interface has nothing to do with the other
150       Perl->GD interface module, aka 'GD' (as in 'use GD;'). This is done
151       from scratch over the years.
152
153       Requires at least version 2.0.22 of the GD library, but it's only been
154       thoroughly tested with gd-2.0.33, so it would be best to use that. The
155       2.0.22 requirement has to do with a change in GD's font handling
156       functions, so if you don't use those, then don't worry about it.
157
158       I should also add, the statement about "thoroughly tested" above is
159       mostly a joke. This OO interface is very young, and it has barely been
160       tested at all, so if something breaks, email me and I'll get it fixed
161       ASAP (for me).
162
163       Functions that manipulate and query the image objects generally have a
164       'gdImage' prefix on the function names (ex: gdImageString()). I've
165       created aliases here for all of those member functions so you don't
166       have to keep typing 'gdImage' in your code, but the long version are in
167       there as well.
168

FUNCTIONS

170   new
171       Creates a new PDL::IO::GD object.
172
173       Accepts an anonymous hash describing how to create it. Use curly braces
174       here!
175
176       If the hash has:
177
178        pdl => $pdl_var (lut => $lut_piddle)
179           Then a new GD is created from that PDL variable.
180
181        filename => $file
182           Then a new GD is created from the image file.
183
184        x => $num, y => $num
185           Then a new GD is created as a palette image, with size x, y
186
187        x => $num, y => $num, true_color => 1
188           Then a new GD is created as a true color image, with size x, y
189
190        data => $scalar (type => $typename)
191           Then a new GD is created from the file data stored in $scalar.
192           If no type is given, then it will try to guess the type of the data, but
193               this will not work for WBMP and gd image types. For those types, you
194               _must_ specify the type of the data, or the operation will fail.
195           Valid types are: 'jpg', 'png', 'gif', 'gd', 'gd2', 'wbmp'.
196
197       Example:
198
199        my $gd = PDL::IO::GD->new({ pdl => $pdl_var });
200
201        my $gd = PDL::IO::GD->new({ pdl => $pdl_var, lut => $lut_piddle });
202
203        my $gd = PDL::IO::GD->new({ filename => "image.png" });
204
205        my $gd = PDL::IO::GD->new({ x => 100, y => 100 });
206
207        my $gd = PDL::IO::GD->new({ x => 100, y => 100, true_color => 1 });
208
209        my $gd = PDL::IO::GD->new({ data => $imageData });
210
211        my $gd = PDL::IO::GD->new({ data => $imageData, type => 'wbmp' });
212
213   to_pdl
214       When you're done playing with your GDImage and want a piddle back, use
215       this function to return one.
216
217   apply_lut( $lut(piddle) )
218       Does a $im->ColorAllocate() for and entire LUT piddle at once.
219
220       The LUT piddle format is the same as for the general interface above.
