Pozdrav.Evo mene ponovo. Sa čitanjem knjige sam došao do 22 poglavlja. Radi se o knjizi "Razvoj web aplikacija sa php i mysql".
Imam problem sa ispisom teksta.Na pratecem cd u sam dobio kod ali mi pravi problem pri ispisu teksta, odnosno prikazuje mi "invalid font name".
Provjerio sam imam instaliranu GD biblioteku a i neke starije teme sam pregledo pa sam pokusao da prebacim font koji hocu da ucitam iz foldera Windos u xamp u root ali nije moglo...

Evo koda..

Code (php):

<?php

// snip..

/*******************************************

  Initial calculations for graph

*******************************************/

// set up constants

putenv('GDFONTPATH=C:\WINDOWS\Fonts');

$width=500;        // width of image in pixels - this will fit in 640x480

$left_margin = 50; // space to leave on left of graph

$right_margin= 50; // ditto right

$bar_height = 40;

$bar_spacing = $bar_height/2;

$font ='arial';

$title_size= 16; // point

$main_size= 12; // point

$small_size= 12; // point

$text_indent = 10; // position for text labels from edge of image

// set up initial point to draw from

$x = $left_margin + 60;  // place to draw baseline of the graph

$y = 50;                 // ditto

$bar_unit = ($width-($x+$right_margin)) / 100;   // one “point” on the graph

// calculate height of graph - bars plus gaps plus some margin

$height = $num_candidates * ($bar_height + $bar_spacing) + 50;

/*******************************************

  Set up base image

*******************************************/

// create a blank canvas

$im = ImageCreateTrueColor($width,$height);

// Allocate colors

$white=ImageColorAllocate($im,255,255,255);

$blue=ImageColorAllocate($im,0,64,128);

$black=ImageColorAllocate($im,0,0,0);

$pink = ImageColorAllocate($im,255,78,243);

$text_color = $black;

$percent_color = $black;

$bg_color = $white;

$line_color = $black;

$bar_color = $blue;

$number_color = $pink;

// Create “canvas” to draw on

ImageFilledRectangle($im,0,0,$width,$height,$bg_color);

// Draw outline around canvas

ImageRectangle($im,0,0,$width-1,$height-1,$line_color);

// Add title

$title = 'Poll Results';

$title_dimensions = ImageTTFBBox($title_size, 0,$font, $title);

$title_length = $title_dimensions[2] - $title_dimensions[0];

$title_height = abs($title_dimensions[7] - $title_dimensions[1]);

$title_above_line = abs($title_dimensions[7]);

$title_x = ($width-$title_length)/2;  // center it in x

$title_y = ($y - $title_height)/2 + $title_above_line; // center in y gap

ImageTTFText($im, $title_size, 0, $title_x, $title_y,

             $text_color, $font, $title);

// Draw a base line from a little above first bar location

// to a little below last

ImageLine($im, $x, $y-5, $x, $height-15, $line_color);

/*******************************************

  Draw data into graph

*******************************************/

// Get each line of db data and draw corresponding bars

while ($row = $result->fetch_object())

{

  if ($total_votes > 0)

    $percent = intval(($row->num_votes/$total_votes)*100);

  else

    $percent = 0;

  // display percent for this value

  $percent_dimensions = ImageTTFBBox($main_size, 0, $font, $percent.'%');

  $percent_length = $percent_dimensions[2] - $percent_dimensions[0];

  ImageTTFText($im, $main_size, 0, $width-$percent_length-$text_indent,

               $y+($bar_height/2), $percent_color, $font, $percent.'%');

  // length of bar for this value

  $bar_length = $x + ($percent * $bar_unit);

  // draw bar for this value

  ImageFilledRectangle($im, $x, $y-2, $bar_length, $y+$bar_height, $bar_color);

  // draw title for this value

  ImageTTFText($im, $main_size, 0, $text_indent, $y+($bar_height/2),

               $text_color, $font, "$row->candidate");

  // draw outline showing 100%

  ImageRectangle($im, $bar_length+1, $y-2,

                ($x+(100*$bar_unit)), $y+$bar_height, $line_color);

  // display numbers

  ImageTTFText($im, $small_size, 0, $x+(100*$bar_unit)-50, $y+($bar_height/2),

               $number_color, $font, $row->num_votes.'/'.$total_votes);

  // move down to next bar

  $y=$y+($bar_height+$bar_spacing);

}

// snip..
