Subject: [PHP] GD 2.0.28 + PHP 4.4.2 + pixelation :(
Hi All,
I have done some searching via google and some answers say change
copyimageresampled to copyimageresized etc
I have tried all fixes ... to no avail
I have one image here 1280 x 960 (150 dpi) 24 depth
When using the following it pixelates ...
function createthumb($name,$filename,$new_w,$new_h)
{
$system=explode(".",$name);
$src_img=imagecreatefromjpeg($name);
$old_x=imageSX($src_img);
$old_y=imageSY($src_img);
if ($old_x > $old_y)
{
$thumb_w=$new_w;
$thumb_h=$old_y*($new_h/$old_x);
}
if ($old_x < $old_y)
{
$thumb_w=$old_x*($new_w/$old_y);
$thumb_h=$new_h;
}
if ($old_x == $old_y)
{
$thumb_w=$new_w;
$thumb_h=$new_h;
}
$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);
imagecopyresized($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y);
imagejpeg($dst_img,$filename);
imagedestroy($dst_img);
imagedestroy($src_img);
}
Which I am of course calling with
createthumb($add,'../pics/'.$largeval,350,263);
Now ... afaik my new sizes are proportional to the big ones ... but it
pixelates :(
However,
Using an image 1600 x 1200 (96 dpi) 24 depth it works and there is no
pixilation
Can someone perhaps assist now?
Kind Regards,
Steven Macintyre

which should be the correct; use copyimageresampled()

DPI is completely irrelevant.
the '24 depth' sounds like your using a PNG as input rather
that a JPEG (which your function expects)
your not making sure that the new width & height are always
integers. use intval() or ceil() or floor() (depending on your
your and the context)... I have no idea what happens if you pass
floats (or non-numeric data) in the relevant arguments of image*()
functinons but I'm guessing it *could* lead to unexplained weirdness
of some sort.
read the man page for imagejpeg():
http://php.net/manual/en/function.imagejpeg.php
take note of the third argument, personally I always set it to 100,
anything less and clients have a tendency to start complaining about image
quality.

Hi Peter,
" I have done some searching via google and some answers say change
copyimageresampled to copyimageresized etc"
I have tried your suggestion with the same results ... that is what I was
using first :(

read this (it might help):
http://pecl.php.net/bugs/bug.php?id=9491&edit=1
basically, if your lucky, all you need to do is update PDFlib to a newer
version.

STFW: you could manage to type the words 'PDFlib download windows binary' (or
something similar)
into the search box on the home page at google.com (or whatever search engine
you prefer)???

is 'validateForm.php' actually correct?
leave the 'action' blank to have it post to the current URL (regardless of

I would consider an include file for a single, static, 7 item array
rather over-kill - not that it should be a problem either!

what it is.
Duh?
This is the new thing I learned today.
I've been messing around with _SERVER["SCRIPT_NAME"] and
_SERVER["PHP_SELF"] just to make sure the code is portable -- and
then you point out something I've been using for years with html.
Sometimes the details shadow what's in plain sight.
Thanks.

Let's say I have a complicated PDF document, like a Christmas card,
that was made in Illustrator -- too complicated to easily create from
scratch using PDFlib. Is there a way to use PHP make simple text
changes - like changing "Dear XXX" to "Dear John"? I've opened the
files with a text editor and cannot locate the simple text, it
appears to be encoded somehow. The PDF has no security or encryption
in it. Thanks....

Brian:
I'm not saying that there is/isn't a way to do this, but I tried and failed.
In my investigation, I found that the insides of a PDF file are not
conducive to a simple search and replace mechanism. The text is
encoded in some fashion that is not easy to decode and reassemble.
The solution I came up with was to combine the existing PDF file with
my coding and write over (on top of) the old to produce the new PDF
that I wanted. In your case, take your Christmas Card with a big
space where "xxx" appears and then write over that space with "John"
in your new code.
I wish someone would show me a simpler way to do this.

Interesting, that's a good idea. I was not aware that it was possible
to load an existing PDF into memory and then add stuff to it.
