PHP - Images/text Not Scaling To Screen Width

Hi there

I have an image in a directory, that I need to resize on the fly but has to be a background in a div with a max width.  I have to determine the correct height according to this max width.

So I sucessfully I have accomplished this, but its not scaling its jsut giving me the top left corner according to my height width properties.

Here is my working code to grab height and width:
Code: [Select]
$img_path = $CONFIG["full_url"].$CONFIG["upload_folder"].ReadDB($News["image"]);
$max_width = 110;
$max_height = 400;
list($width, $height) = getimagesize($img_path);
$ratioh = $max_height/$height;
$ratiow = $max_width/$width;
$ratio = min($ratioh, $ratiow);
// New dimensions
$mywidth = intval($ratio*$width);
$myheight = intval($ratio*$height);
Now using those I need to resize the image proper to get it centered up.  I dont really want to save the file I just want to display it.  Is this possible?

My attempts have garnered a bunch of crazy characters on screen and not an image.

Here is the code I added to the end:

Code: [Select]
// Resample
$image_p = imagecreatetruecolor($mywidth, $myheight);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $mywidth, $myheight, $width, $height);

// Output
imagejpeg($image_p, null, 100);

Then Im using it on the page like so:
Code: [Select]
<div class="theimg" style="display:block; width:<?php echo $mywidth;?>px; height:<?php echo $myheight;?>px; background-image:url(<?php echo $image_p; ?>); background-repeat: no-repeat;"/>&nbsp;</div>
and heres what I get :/


What am I doing wrong??  The image is not displaying inside its rounded corner border and we have crazy crap on top.

Thanks in advance

When i upload photos and the name of the photo i would like to be able to overlay a portion of the original photo with another image already in the site directory, and also add the photos name over the top of the overlayed image,  i may have explained this in a confusing way so i have attached an example.

Is this something that can be done using something like GD or imagick, if so could someone please give me a good place to start.

Hi All,

i am trying to Generate a image dynamically.
Up to here i am able to do it .
But when i give any echo statement with this its not working..
Here is my code pls help me in this

<?php
// Create a 55x30 image
$im = imagecreatetruecolor(79, 79);
$unknow = imagecolorallocate($im, 0, 255, 255);
$white = imagecolorallocate($im, 255, 255, 255);

// Draw a white rectangle
imagefilledrectangle($im, 4, 4, 75, 25, $unknow);
imagefilledrectangle($im, 4, 29, 75, 50, $unknow);
imagefilledrectangle($im, 4, 54, 75, 75, $unknow);

// Save the image

echo 'hi hello';
header("Content-type: image/png");
//imagepng($im, './imagefilledrectangle.png');
imagepng($im);

imagedestroy($im);
?>


Thanks in advance.

So on a cloud computing platform such as AWS, how would one keep the /html folder in Apache identical?   I can FTP into one "instance" and modify code easily enough, but how would I push reversions to multiple servers at once?   It seems like such a simple question, but the answer eludes me.

hi, how is everybody doing? i hope well, i have a problem with some php code. i am trying to split some text in two parts once they have been split, they are display, but sometimes the php code break the source code of the page such as images and instead of the image i get the source code like this
Quote

add-plugins-paintnet-1.2-800x800
3857cff9733e6a.jpg" style="border-width: 1px; border-color: #000000; border-style: solid; margin: 4px auto 5px; display: block;" />

i have tried for about 2 days now to fix it and i haven't been able to, so any help or guidence would be greatly appreciated. this is the code that i am currently using, i have tried to change the variable in the $findTag but nothing seems to work
Code: [Select]
<? php
$article =$this->article_>text;
$countchars=strlen($article);
$divide=$countchars/2;
$firstpart=substr($article,0,$divide);
$secondpart=substr($article,$divide);
//i keep changing the <p /> variable to <img /> and $image and many others but nothing seems to work
$findTag = strpos($secondpart, "<p /> ");
$var = $divide + $findTag
$firstpart = substr($article, 0, $var);
$secondpart = substr($article, $var);
?>
thanks

When I asked about adding a watermark to a video, this was suggested: "when scaling it, I'd do h/5:w/5 (of the source video), then position would be w/20 (5% from the left) and h-h/3 (75% of the way down)

When I asked about adding a watermark to a video, this was suggested: "when scaling it, I'd do h/5:w/5 (of the source video), then position would be w/20 (5% from the left) and h-h/3 (75% of the way down)"

I'd like to try that, but I don't know how to integrate that into my existing working code:

 $ffmpegCommand =''.$ffmpeg_b.' -y -i '.$video_file_full_path.' -i '.$watermark_image_full_path.' -filter_complex "scale=426:-2, overlay=10:10, " -vcodec libx264 -preset '.$pt->config->convert_speed.' -crf 26 '.$video_output_full_path_240.' 2>&1';

I've looked at the ffmpeg documentation, but need additional assistance. any help is appreciated

 

 

I'm trying to make my text and images into clickable links. The images and text are in a database so its getting really tricky for me since I'm new to PHP. I've tried many different ways without success.

Here is a snippet of the code I'm working with. As you can see, I'm also working with an image re-sizer. I would really like to make those images and text
clickable links(i.e. Title). Any help is appreciated!

if ($res) {
while ($newArray = mysqli_fetch_array($res, MYSQLI_ASSOC)) {
$detail = $newArray['id'];
$photo = $newArray['photo'];
$id = $newArray['title'];
$price = $newArray['price'];


list($width) = getimagesize($photo);
// set the maximum width of the image here
$maxWidth = 100;
if ($width > $maxWidth)


echo "<p><img alt=\"Image\" width=\"$maxWidth\" src=\"$photo\" />";

echo "Title:".$id." Price:".$price."<br/";

the idea on what im doing is like a converter, like showing what your name would look like with certain images per letter, when you input text (your name for example) and when you press the submit button you would get a series of images in a row that represent each character that you typed.   here is the example that i did...

Hello. After much searching I dont seem to be able to find anyone who has had this issue.

I am writing a bounce handler.
To get the bounced email of the original recipient I need to download the TEXT part of the bounced message.

The original message contained INLINE Images.
Many of the bounced messages are returned what appears to be the INLINE image embedded as text in the TEXT part of the email.

This means I am having to download TEXT parts which are many MB in size when all i need is about the first 1Kb to get the email address and status code.

Does anyone know if there is an IMAP  parameter/command that I can tell it to only download the first   NNN BYTES of the TEXT Part.   

I have seen this done using  FOPEN to read messages.

I have this script from http://lampload.com/...,view.download/ (I am not using a database) I can upload images fine, I can view files, but I want to delete them. When I press the delete button, nothing happens   http://www.jayg.co.u...oad_gallery.php   <form> <?php $dir = dirname(__FILENAME__)."/images/gallery" ; $files1 = scandir($dir); foreach($files1 as $file){ if(strlen($file) >=3){ $foil = strstr($file, 'jpg'); // As of PHP 5.3.0 $foil = $file; $pos = strpos($file, 'css'); if ($foil==true){ echo '<input type="checkbox" name="filenames[]" value="'.$foil.'" />'; echo "<img width='130' height='38' src='images/gallery/$file' /><br/>"; // for live host //echo "<img width='130' height='38' src='/ABOOK/SORTING/gallery-dynamic/images/gallery/ $file' /><br/>"; } } }?> <input type="submit" name="mysubmit2" value="Delete"> </form>   any ideas please?   thanks

Hello. The first page works, but when form actioning to the next i just get a white screen.   This is the white screen page:   <?php

        $row = mysqli_fetch_array($query);

if(!empty($row['name']) AND !empty($row['pass']))
    {
$_SESSION['username'] = $row['username'];
$_SESSION['id'] = $row['id'];

Ok,


I know how to screen scrape, but I don't know how to screen scrape when there is a login. I've looked this up for awhile, but no luck.
I'd like to also make it so I can execute a url when I am logged in on the script for the script, for an example execute this url: http://site.com/data.php?id=9912&submit=1

Thanks in advanced.
