PHP :: Imagerotate(), Producing A Black Background Color

Retaining Black Color
What I'm doing is changing the color of one image and then overlaying it on top of another with an opacity of around 35%. The bottom image contains pure black text. What I want to know is if there is a way to merge the two images while retaining the color of the black text underneath. A lot like using a multiply layer in Photoshop. I'm not even sure if this is possible, or if I'd be simply better off just having a separate layer/image just for my black text.

GD Imagecopy Problems With Black Background
This function is part of a class, it basically creates a new image in the dimensions specified, and then copies in the image held in $this->image. The image that is copied in will never be bigger than the new image (that is taken care of in another function) but one or both of the dimensions could be less than the new image (if the ratio isnâ€™t the same).

It all works perfectly, it creates a new true colour image, fills it in white, but then when it runs the imagecopy function it seems to forget the fact that I set the background to white, and the image that results has a black border.

For example if I wanted a 100x100 image, and I was copying a 100x50 image in, I would end up with a 100x100 image with the old image centred vertically and a 25px black stripe above and below, I want those stripes to be white.

Any ideas?

function crop($width = null, $height = null)
{
// get the current widths and heights
$current_width= imagesx($this->image);
$current_height= imagesy($this->image);

$crop_top = floor(($current_width - $width) / 2);
$crop_left = floor(($current_height - $height) / 2);

// create a new image resource
$temp= imagecreatetruecolor($width, $height);
$white= imagecolorallocate($temp, 255, 255, 255);
imagefill($temp, 0, 0, $white);

// copy image into new resource
imagecopy($temp, $this->image, 0, 0, $crop_top, $crop_left, $width, $height);

// destroy original image
imagedestroy($this->image);

// copy new image
$this->image = $temp;

PHP (GD) Created Transparent PNG: AlphaImageLoader Makes Black Parts Transparent Instead Of Transparent Color Set With PHP
I have a problem with PHP (GD) created transparent PNG and Microsofts
AlphaImageLoader.

You will immediately see what the problem is if you view
http://www.useful-scripts.biz/test/.../transpng_2.php with IE 7
or Firefox and then with IE 6. It seems that the AlphaImageLoader
works correctly on a PNG image that has been created with an image
processor and then uploaded, but not with a PNG image created with
PHP. It seems to ignore the transparent color set with PHP and instead
to render the black color transparent.

The image in question was created using this code:

<?php
$source = imagecreatefrompng("parrot_orig.png");
$transp = imagecolorallocate($source,255,0,0);
imagecolortransparent($source,$transp);
imagefilledrectangle($source,15,15,70,70,$transp);
imagepng($source,"parrot_php.png");
?>

Imagerotate With GD
I am trying to do. I have two images. I need to rotate both of them (2 different degrees, which is determined by a random number), then I need to merge them together so that the center of both images are on top of each other. So far, I have both images, I rotate them, and I use imagecopymerge() to put them together. As far as I can tell, the reason for this is that they are square images (both 200x200), and depending on how they rotate, the corners of the boxes are kind of pushing the image in defferent directions, causing them both to shift around the page a little bit, and not line up properly when merged.

GD2 Producing Empty Images
I've found a problem with many of my PHP installations. I'm not sure whether it's a PHP problem, or an Apache problem, or something else again.

The issue appears when we try to use the following snippet from the PHP docs for imagecreate():

<?php
header("Content-type: image/png");
$im = @imagecreate(100, 50)
or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 255, 255, 255);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, "A Simple Text String", $text_color);
imagepng($im);
imagedestroy($im);
?>

This brings up an empty page. FF Page Info shows a 0px x 0px png. I'm using Win2K on 2 of my 3 machines. On the 3rd, XP machine I'm using xampp which uses Apache 2, and it works on that one.

Currently trying to install xampp on my main workstation (win2k), but can't get existing port 80 server cleared... That's another issue.

Anyone have similar problems with GD2 in PHP?

This Class Returns HTML Content But Fails In Producing Globals, Why?
The following class is supposed to produce a series of HTML dropdowns
and HTML text fields based solely upon variable names for month, day
and year passed into it. Those variable names will correspond to
actual variables with values that are passed into the preSelect()
function inside the methods (that function is called from an outside
parent script included). However, upon careful inspection the global
function does not globalize anything within any method.

// USE THIS CLASS TO GENERATE A SERIES OF DROPDOWNS AND TEXT FIELDS
PERTAINING TO MONTH / DAY / YEAR
class DropdownGenerator {
var $hasMonth, $hasDay, $hasYear,
$monthVar, $dayVar, $yearVar,
$yearFieldLength,
$monthArray;

function DropdownGenerator($monthVar = '', $dayVar = '', $yearVar =
'', $yearFieldLength = 4) {

$this->yearFieldLength = $yearFieldLength;
foreach (array('month', 'day', 'year') as $key => $val) {

0) ? 1 : 0;

Problem With "imagerotate"
Does the "imagerotate" function in PHP5 work correctly or am I doing
something wrong?

I'm using the code shown below to generate a simple rectangle and then
to rotate it a specific number of degrees. The actual rotation itself
seems to happen OK but the background color appears correctly only if
the rotation is between 1 and 45 degrees; any other value and the
background is black. And, in neither case does the
"imagecolortransparent" work (I want the background to be
transparent).

$myImg = imagecreate($somelength,$somewidth);
$myBG = imagecolorallocate($myImg,85,255,255);
$RectColor = imagecolorallocate($myImg,200,200,200);

Black Hat Or Not? Linking Technique Using PHP
I had an idea that I wanted to see what people think of it. I'm optimizing a site that is already built w/ very generic file naming and directory structure. In other words, I don't have directories or file names that intentionally have keywords in them. For the most part, its just a lot of index.php and one-word names.

So now I'm trying to figure out a way to get some keyword URL's in there w/o trashing my directory structure.

Here's what I'm thinking:

Let's say I have a link already in the page that goes to index.php. What if I changed the link to keyword_term.php, then I put the following code in keyword_term.php:

<?php
$no_spider = "TRUE";
include "index.php";
?>

index.php would then have this in the header:

<?php
if ($no_spider = "TRUE") {
echo "<META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">";
}
?>

I know it seems like more work than its worth, but the idea is that in the long run, I can optimize multiple pages for different keywords, while requiring little maintanence if I decide to edit the original index.php. I'm also using the $no_spider variable to aviod being penalized for duplicate content. My intention is not to get index.php indexed multiple times, just to allow other pages to link to it using different file names.

Imagecreate Output A Solid Black Image

Actually, only $final_im creates an image that's solid black. If I used $im as the output file (if I use this instead: imagejpeg($im, "$new_name") ), it's fine (albeit a very low quality image that does not have the dimensions I desire).

Imagecreate :: Resized Images Appear As Black Squares
I dont know why this is happeneing, but all my resized images are being saved as just black squares. It uploads an image of the correct size, to the correct directory. problem is its just a vlack square that it creates. i cant get it to actually put the origional into it. From looking at the code i cant honestly understand why this doesnt work Code:

<?php
$image = imagecreatefromjpeg("../../member_pics/full_size/".$new_filename);
if ($image === false) {
die ('Unable to open image');
}
$width = imagesx($image);
$height = imagesy($image);
// New width and height
$new_hieght = "100px";
$new_width = "100px";

Problem W/ Imagecreate() To Pdf ->image Printing Black Fuzz
this may be an issue with printer or something but i was wondering if anyone had seen this before??

info....
-the application is a work order request form that generates a pdf of form w/ user's input filled in.
-a unique "request number" is created and is put in the pdf via imagecreate() - black text on a white background.

for some people, the image/request number displays fine but when printed, is a black fuzzy block (see image below)

taken from scan of printed form: http://www.alumni.uga.edu/it/beta/request_num_pdf.gif
