Use Php Gd To Apply Texture Image On Top Of Another Ignoring Transparent Pixels	View Content

I’m trying to work out how I can use php gd to take an image, in this case it’s a rectangle that has text in the middle and the rest is transparent, so it’s a png with just text in the centre.

I have another image which is a texture. Its also a rectangle of the same size. I have managed to merge the two together so the texture on top of the text image but it covers the entire image rather than just the text in the middle.

what I need it to do it apply the texture to the text in the image and ignore the surrounding transparent pixels.

I am trying to copy an image into another image.

Code: [Select]
$im = imagecreatefrompng("/oldimg.png"); //this is a semi-transparent image where I want the new image to be copied

imagealphablending($im, 1); //this seems to remove the black background

header('Content-type: image/png'); //outputs old image with a transparent background (YAY!)
imagepng($im);

imagecopy($im, $newimage, 32, 0, 0, 0, 32, 32); //I want to replace a part of the old image with a new semi-transparent image

header('Content-type: image/png'); //outputs image with a black background (noooooooooo!)
imagepng($im);

Gd Library - Colorize Non-transparent Areas In Image

Similar Tutorials

View Content

I'm wondering if the GD library is capable of coloring ONLY the non-transparent areas in an image. I had this image white, black, and every other color under the moon, but could only get GD to color the entire canvas (width and height) of the image with an opacity over it. I'm merging many layers on top of each other so I can't afford to color the entire square and lower the opacity and do some weird multiply stuff. That's the image above. Then I have some lineart, markings, eye color, etc. So I had all my possible colors white areas that I layer on top of eachother. I want to color the entire non-transparent areas with a color (dynamic).. so I can't just color it in Photoshop and then upload it or else I would literally have millions of possibilities for every single color and shade.. Thanks for any help. I was trying to go with ImageMagick if GD isn't capable, but I can't even get that downloaded in my Wamp. I'm using 64 bit Wamp so I have no idea if that does something or whatever. I can get it installed on my computer and run it via command line, but I can't get it to work and render images in my Wamp files... can't ever find a .dll that works.

Hi,

I have a database table which is full of books e.g book_title, book_author, book_date etc. Im trying to work out a way to list all the authors without duplicating them, if that makes sense.

If I do a simple query and then display the book_author in a loop it will show multiple entries for each author.

I just want it to display each author once.

Hope that makes sense lol sorry Im a newbie.

Anyone know how I can do it ?

Thanks in advance,

Hi Folks,

I am trying to scrape the price data from a webpage, but how to get the variable,

see here the target http://www.buergerstiftungen.de/cps/rde/xchg/SID-635E10F9-BFA1A4BF/buergerstiftungen/hs.xsl/db.htm

Code: [Select]

$info1 = $html1->find('b[class=[what to enter herer ]',0);

The variable then also contains data such as

 info 

Is there a way to trim the unwanted data out ? I just need all the infos out of the site. I am unsure if I do it during the find, or perhaps when i echo out the variable, then do I specify what I want ?
well how t o do it witout a regex but with DOM-Document!?

Apply Trim On Whole Array?

Similar Tutorials

View Content

Is there a way to apply the function trim() on a whole array, instead of applying it to the individual input fields one by one?

Here's the code:

$blurb1_title = array (
$_POST['blurb1_title1'],
$_POST['blurb1_title2'],
$_POST['blurb1_title3'],
$_POST['blurb1_title4'],
$_POST['blurb1_title5']
);

$blurb2_title = array (
$_POST['blurb2_title1'],
$_POST['blurb2_title2'],
$_POST['blurb2_title3'],
$_POST['blurb2_title4'],
$_POST['blurb2_title5']
);

$blurb3_title = array (
$_POST['blurb3_title1'],
$_POST['blurb3_title2'],
$_POST['blurb3_title3'],
$_POST['blurb3_title4'],
$_POST['blurb3_title5']
);

All those $_POST variables are input fields, and I would like to apply trim() to them so the spaces get removed.

Is there an efficient way to do it without having to apply it all individually, if yes, what would be the correct syntax?

Read Htaccess Commands By Php And Apply It

Similar Tutorials

View Content

Hi; I would like to make a php script read the commands in the htaccess file and apply those commands to itself. Here is an example : htaccess commands :

RewriteEngine On

RewriteCond %{QUERY_STRING} badword
RewriteRule .* - [F]

The meaning : Deny any request in witch the query string contain the word badword The translation into php code :

if( strpos($_SERVER['QUERY_STRING'], 'badword') !== false )
{
header('HTTP/1.1 500 Internal Server Error');
exit(0);
}

Now this example is simple, but how to translate more complex htaccess commands with multiple RewriteCond and complex regular expressions into php commands like the one i did ? or better is there any php script that read an entire htaccess file and apply the rule it read on it ? Thank you

How To Apply A Condition To The Display Of An Array

Similar Tutorials

View Content

I have the following code that queries the database for the results of a quiz.
The display reports on completed quizzes, showing, line by line, the quiz title, the date of the quiz, an image of a green tick if the quiz result was correct or an image of a red cross for an incorrect result and a fractional result shoratio of correct answers.
A student can repeat a quiz numerous times, and therefore his results for a particulat quiz can display several rows with green ticks and red crosses for the same test done at different times with differing results.
I want to recode this so that the red crosses for incorrect results will no longer display once a student achieves a green tick result.

I've had several goes at this but my results are less than encouraging.
Can anyone help?
Do I tackle this through an altered query, or should I include conditions in the display of the array?
Code: [Select]
<?php
$query1 = mysql_query("SELECT DISTINCT quizTitle, userId, passState, userScore, totalScore, DATE_FORMAT(userDate,'%b %e, %Y') AS userDate FROM quiz WHERE managerId = '$managerId' AND userId = '$userId' ORDER BY quizTitle, userDate ASC");

while ($row = mysql_fetch_array($query1))
{
 echo "{$row['quizTitle']} \n";
 echo "{$row['userDate']} \n";
 if ("{$row['passState']}" == 1) {echo "<img src=' ../../wood/wood_tool_images/tick2.png' /> \n";}
 if ("{$row['passState']}" == 0) {echo "<img src=' ../../wood/wood_tool_images/cross2.png' /> \n";}
