Voici ce que j'obtien:
pdf-api2.pl.pdf

mais ça ne correspond pas à mes attente au niveau des images jpeg.
en fait je n'attendais à avoir deux images distincte et non similaire.
Alors qu'avec les png; ça marche.

si je met dans la fonction "print_img" un sleep(5):

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
 
sub print_img {
...
 
sleep(5);
}

l'image temporaire qui vient de ma base de donnée, change bien, mais pas dans le pdf de sortie.

le paramètre "parm" change bien entre les deux appels pour "print_img" pour les appels sucessif:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
8
9
10
11
 
$param = "1";
print_isbn($page, $pdf, $param, isbn_x, isbn_bas, 25, 15);
$param = "3";
print_img($page, $pdf, $param, img01_x,img01_bas, 25, 30);
 
 
$param = "2";
print_isbn($page, $pdf, $param, isbn_x, isbn_haut, 25, 15);
$param = "4";
print_img($page, $pdf, $param, img01_x, img01_haut, 25, 30);

Donc qu'y aurait-il qui fait que ça ne prenne pas les images successif ?

Je vous remercie, d'avance de vote aide.

Bonne soirée

Salut à tous,

Pour ceux que ça intéressent...

j'ai contourné le problème en y ajoutant une variable globale dans la quelle je mets l'url où est stockée l'image temporaire. Je mets autant d'image temporaire qu'il y a d'image et non une image pour tous. Je n'ai pas trouvé d'autre solution.

la variable globale:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
 
my @tableauNomJPG; 
my $i = 0;
 
my @tableauNomPNG; 
my $j = 0;

dans print_img:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
8
9
10
11
12
 
my $nomImg = sprintf ( 'temp%09s.jpg', $i);
print $nomImg."\n";
mkdir nomDossier;
my $url = '.\\'.nomDossier.'\\'.$nomImg;
print $url."\n";
push (@tableauNomJPG, $url);
 
...
 
 
$i++;

et dans output_img_temp

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
 
open OUTPUT, ">".$tableauNomJPG[$i];

j'ai fait de même pour les images png

ce qui donne le code suivant:

Sélectionner tout - Visualiser dans une fenêtre à part
