StringFT under mod_perl

Hello,

I'm having this annoying problem for 3 days now and can't find a solution

I made a script for creating images using GD, under mod_cgi it works just fine, but once I run it under mod_perl it gives a blank page, it's not a matter of persistent variable because when I change "stringFT" to "string" the script start to work under mod_perl as well

$image->stringFT($black,'/path/to/truetype.ttf',18,0.0,60,10,"some text");

this gives a blank page

$frame->string(gdTinyFont, 390, 48, "some text", $black);
but changing to "string" the script run just fine under mod_perl

I want stringFT to work under mod_perl

Please help as this cosuming my life and strangly no solution any where else

Thanks in advance

I've recently been playing about with GD,

perl Code:

Original - perl Code
$Image->stringFT( $black, # color 'C:/Windows/Fonts/ARIBLK.TTF', # font $sets{'Large_Font_Size'}, # font size 0, # angle $sets{'big1x'}, # x coordinate $sets{'big1y'}, # y coordinate $lines[0], # string {linespacing=>0.6, charmap => 'Unicode'} ) or die $!;

$Image->stringFT(
                $black,            # color
                'C:/Windows/Fonts/ARIBLK.TTF',  # font
                $sets{'Large_Font_Size'},       # font size
                0,              # angle
                $sets{'big1x'},    # x coordinate
                $sets{'big1y'},    # y coordinate
                $lines[0],       # string
               {linespacing=>0.6, charmap  => 'Unicode'} ) or die $!;

has worked for me, could it be that the root directory is different under mod_perl, and that it can't find the font, try copying the font file into the same directory as the script and see if that sorts it. Mod_perl may have some security which jail roots the script in terms of what it can access

Thanks Axweildr,

I already did that, you will not believe me if I said that during these three days I tried every thing, I recompiled libgd and installed GD again and again thinking it's a freetype issue and mod_perl can't find freetype library, and I'm having really odd results every time I configure the server, so it's more likely a server issue not a script

Here's one more thing to try

perl Code:

Original - perl Code
$image->stringFT($black,'/path/to/truetype.ttf',18,0.0,60,10,"some text") or die "$!\nOoops ...";

$image->stringFT($black,'/path/to/truetype.ttf',18,0.0,60,10,"some text") or die "$!\nOoops ...";

you did try putting the font in the same directory as the script, and referring to it as just

perl Code:

Original - perl Code
$image->stringFT($black,'truetype.ttf',18,0.0,60,10,"some text") or die "$!\nOoops ...";

$image->stringFT($black,'truetype.ttf',18,0.0,60,10,"some text") or die "$!\nOoops ...";

Axweildr sorry for the late and thanks for your help effort

Yes I did point the path to the same folder and moved font file there too, and else I use mod perl to handle files in another path and all works just fine

It's the first time I feel so desperate and the first time I think to get another server

just to solve this issue

No just white blank page, that's what really annoying, why there is no error message?
