Re: [PHP] image inventoryer
Kirk: Okay, you took the first step. Now please review this: $filename "); } ?> Note: 1. This example does not put in all the embedded formatting shown in your example. What you did was simply bad form -- you should learn css as well. Also, you don't need to place the code within a bunch of html -- it will work "as-is". 2. I always want my students to place images in an image directory -- the above conforms to that. 3. The example also shows how to separate the jpg's from other files in the directory. So, where do you want to go now? Cheers, tedd _ tedd.sperl...@gmail.com http://sperling.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] image inventoryer
Thank you!
Not QUITE the first; I have used snippets and small routines for a
while; however I did not know how to do this in php.
Turns out there are at least 2 methods: glob, and an iteration of
the directory with readdir() to build up an array, then one by one
print the elements in the array. In python this is not hard.
Iteration in python is somewhat different- not to mention getting
used to do blocks. Being so used to snake charming, learning a new
way means getting used to different procedures.

My first thought was that the current working directory is probably set
differently. However, you say that the script works and presents the rotated
images, it's just the cache that isn't right. I still think I'm probably
correct, so try these changes...
> $im = dirname(__FILE__).'/'.$_GET['im'].'.png';
and...
> $save = dirname(__FILE__).'/cache/'.$_GET['im'].'_'.$degrees.'.png';
You also have a pretty major hole here because you're taking a querystring
parameter and putting it straight into a command line. What happens if I pass
the value of $_GET['im'] as "../../../../../../../../../../../etc/passwd" ? Use
escapeshellarg when putting variables into command lines to protect against
this type of hack.

[PHP] Image question for runways
Hi,
I am trying to create an on the fly image of runway layouts but am
hitting a brick wall.
I have both the starting and ending coordinates of each runway, it's
length, as well as it's angle of direction (heading).
I can draw one runway without any problem, but where I am falling short
is how to 'scale', if that is the right word, the other runway(s) to
display properly in a 500x500px image
function imagepolarline($image,$x1,$y1,$length,$angle,$color)
{
$length=($length/500)*20;
$x2 = $x1 + cos( deg2rad($angle-90)) * $length;
$y2 = $y1 + sin( deg2rad($angle-90)) * $length;
imageline($image, $x1,$y1,$x2,$y2, $color);
}
//'base' coords
$x1=200;$y1=200;
$scale=1;
//if first runway
if ($d==0) {$xbase=abs($lon1);$ybase=abs($lat1);}
//for all others
else
{
$x1=$x1+(($xbase-(abs($lon1)))*$scale);
$y1=$y1+(($ybase-(abs($lat1)))*$scale);
}
Here is some test data if that would help:
"length","lat_start","lon_start","heading","lat_stop","lon_stop"
"6869","38.8424","-77.0368","355.5000","38.8612","-77.0387"
"4911","38.8423","-77.0408","26.","38.8544","-77.0333"
"5204","38.8617","-77.0438","142.7000","38.8503","-77.0327"
Any suggestions would be most appreciated.

However, I've also worked on apps where the balance appeared to shift towards storing the image in the DB. For example, we were running ASP.Net, had 1 load balancer, 3 web servers, and 1 super-duper DB server (the site is subject to very large spikes, and generally high traffic.) The client used my custom CMS to administer content, including images (not for the site templates, but rather for the items they were specifically managing on their site.) I could have chosen to store the images on one of the web servers, but that posed issues in terms of maintenance and also the webservers were not as reliable as the DB (per SLA and the equipment used, as the DB server had internal redundancies built-in, and those who've worked with IIS are likely familiar with the "It's not working, let's just reboot" methodology for servers.) I could have duplicated the images across all of the servers. However, keeping things synched, when coupled with the security requirements, proved to add a fair amount of complexity (not that it was impossible, but troublesome given the budget, timeline, and the fact I wasn't the sa.) I could have set up another server as a media server, but that wasn't logistically feasible at the time (there are other options I've not mentioned, too.) I decided to examine the performance of an architecture where we stored the images in the DB, as this app was unique in a few ways. First, each image was limited to less-than 45KB (pretty small.) Second, the DB is relatively small, containing thousands of items that they manage (old records are frequently purged.) After running several benchmarks, I realized that the website performed very well using this architecture (although I found several other issues in terms of performance, not that they were because of my [cough] code ;) I sometimes hear people lament the speed of PHP. As Rasmus Lerdorf points out in his presentation "Simple is Hard" ( http://talks.php.net/show/froscon08), PHP is rarely the bottleneck. When I ask those who take issue with PHP's speed what they're basing it on, I find few back it up with meaningful numbers, or if they do, they're pointing to the comparison of PHP to some other language while running a for loop, which is interesting if you're writing a for-looper app. Rarely have these naysayers benchmarked PHP in the greater ecosystem o

[PHP] PHP Image Host - Sending HTTP Headers Twice?
I have a php script which serves an image. It's very simple:
header('Content-Type: image/' . $ImageData['content_type']);
readfile($File);
When viewing the script with the Firefox Extension: LiveHTTPHeaders,
it gives the following output for a SINGLE request:

Re: [PHP] image upload keeps file name ?
I use the follwing function for moving files:
public function moveFile($file,$targetdir="../uploads/images/")
{
$fileName = $file['name'];
$ext = substr($fileName, strrpos($fileName, '.') + 1);
do
{
$targetfilename=md5(date("m.d.y.h.i.s").basename($fileName)).'.'.$ext;
$fullname=$targetdir.$targetfilename;
}while(file_exists($fullname));
move_uploaded_file($file["tmp_name"],$fullname);
return $fullname;
}
Call the fn as :
foreach($_FILES as $file_name => $filearray)
{
if( $filearray['error']=='')
{
$filenametobestored=moveFile($filearray);
/*Enter name into db here*/
}
}
this will make sure you never over write anyfiles..

Yes, the original filename comes from the ["name"] array element.
However, if someone is uploading a filename with the same name as one
that already exists, you will be overwriting it.
For peace of mind, I've always found it best to save the file using the
tmp_name given to it by PHP, and store this against the original
filename in a database. You can then use PHP to deliver the file back to
the user when it's needed as either a download or something displayed in
the browser. This works nicely with storing files outside of the web
root, which will prevent people from maliciously uploading files to
attempt to break your server and/or app.

@Adam
The headers_sent() wasa test to ensure that no other data was creeping
into the headers before I wanted it to. Keeping it in does no harm, as
it is basically saying, if there are no headers that have been sent,
send the correct ones for the image.
@Martin
The image is being produced by PHP. The command I'm using to output the
image is image_png(), and my OS is correctly reporting a PNG image
(Linux will use the extension as a hint, but gets the filetype from the
contents). Also, for further clarification, the junk output I'm getting
has the letters PNG in the first few characters, so I'm pretty sure this
is a PNG image yes!

I've got a bit of a weird one here. I'm using PHP to output an image. This works fine when I output as a file, but when I try to feed it directly to the browser it fills the screen with random characters. I know I've got the headers right, as it works some of the time. The only thing I can spot when it does fail is that some of the image drawing commands are essentially drawing off the edge of the image area.

[PHP] Image Type BMP @ "Save Image As" Dialog on IE
I have wrote a PHP script that serves JPEG images in smaller size, the resize is done using GD on-the-fly. I have noticed an interesting issue during the "save image as..." dialog on serveral internet explorer browsers, somehow, for some strange reason, the JPEG file is shown as BMP file. I don't know why this is happening, but I'm trying to make it save it as JPG file. In firefox or any other browser everything works like a charm. I have to mention that the JPG file is located in the HTML in the following format: I have also used mod_rewrite to serve the file with .jpg extension (I thought that the strange IE may not know how to recognize it..), the PHP file is sending the correct headers, I'm attaching an example for HTTP request & response for this resized image: GET /gallery-image-dolphinim-12450163853.

Re: [PHP] Image Resizing
i use imageMagick:
http://www.imagemagick.org/Magick++/Geometry.html
$command_line = "convert -geometry $width" . "x" . "$height $image_path
$thumb_path";
system($command_line, $return_var);
if ($return_var == 1) {
echo "Thumbnail creation failed! :(";
} else {
echo "Thumbnail created. :) View
Thumbnail FFS";
}
?>
if you run into problems, and assuming imageMagick was successfully
installed:
- make sure you have write permission for where you want the thumbnail to be
created
- try replacing convert with the full path to the convert app.
e.g.
$command_line = "/usr/bin/convert -geometry etc";
- run the script from the command line. ssh in to your script's directory
and try typing this:
php thumbscript.php
you'll see verbose messages to help you pinpoint the problem. depending
on your setup, you might have to put in the full path to php
- if you're still stuck, try putting in this line:

Of course, real programmers keep it all in their heads... Nah, I guess I've just not worked on anything complex enough that I've needed the tree view yet. Mind you, this new project I've been assigned to could well be going that way. It's a mess of a system written in C# and it keeps crashing regularly to boot. Somewhere along the line I think a sadist got involved in the project, because it's really painful to work with sometimes...

RE: [PHP] php image and javascript include
I'm a big fan of Zend Studio 5. It's pretty hard to beat considering how fast you can code load up the page refresh, and the editor itself is very clean plus it works in linux. I know a lot of people like to soft tab but I just don’t have the patience. Hard tabs all the way for me.

Re: [PHP] php image and javascript include
I've never been a huge fan of Vi or Vim, but I am a fan of coding in a text editor, not a GUI, I just guess I prefer Kate. I know for certain that one thing that really bugs me about Dreamweaver is the fact that it has a tendency to really nerf up the spacing, and it replaces tabs with spaces more often than not. It's all about the tabs to space things out, adding spaces just makes the files bigger!

Re: [PHP] php image and javascript include
Kate has an auto text feature, and you can set it to start prompting from typing in as few characters as you wish, although it only prompts for things you've already typed, it this does save you from making obvious variable name typos as it will prompt the next time you try to use it, and it recognises many, many more languages than DW. If you're just after the code view, Dreamweaver is a little heavy, and it runs on an OS which is also a bit heavy, but that's for another discussion!

Re: [PHP] php image & javascript issue
In my test.php file, I cannot run javascript and images do not show up. If I
run this file using the URL
http://localhost/index/?m=login&name=Sachin
I can see 'My name is Sachin'.
If I rename this file to test.html and open it, the image shows up and
clicking on 'Click Me!' button works fine.
Pls uncomment the tag when you run it.

[PHP] php image & javascript issue
In my test.php file, I cannot run javascript and images do ot show up. If I
run this file using the URL
http://localhost/index/?m=login&name=Sachin
I can see 'My name is Sachin'.
If I rename this file to test.html and open it, the image shows up and
clicking on 'Click Me!' button works
http://www.nabble.com/file/p19376008/login.png fine.

Re: Re: [PHP] Image Generation
Hi Alex,
I did reply to this, but it apparently didn't get to you. You will need
to create a separate image with the text in, as GD offers no function to
create text already stretched (actually, it's text offerings are sparse
to say the least). You can create this image in memory if you are
worrying about creating a lot of files on your server though, and then
perform resizing operations on the image in memory.

Just to clarify some points, there is no need for this to be of
print quality - it is an online representation of the vinyl they will
recieve in the post.
Also, the main problem I've got with GD, is generating text that is
stretched? Do I need to generate a text image then stretch this using
normal resize functions??

I can't see how imagemagick helps here, it's a bitmap manipulator
just like
GD. so it's either use something that generates vector based output
(and let
the printersubsytem handle the conversion) or generate massive
bitmaps and
print them at a very high DPI.

I'll take your word on that, I've never played with imagemagick,
having found
GD to produce quality good enough for my needs.

Re: Re: [PHP] Image Generation
Yes, if you wish to stretch text in this way then you will have to
create the image and stretch. You can create the image in memory and
perform the stretching on it there if you are worried about writing too
many temporary images to the server.

GD can do all this, although I hear said that ImageMagick does more and has
somewhat
better output.
you'll only be able to offer fonts that you have installed on the server, also
image generation works in pixels so you'll have to come up with a way to
'convert'
millimeters to a pixel value for display purposes.

I would like to find some samples to start with. We want to upload a picture and the user may apply some "filters" or "instructions" to create a new picture, based on the uploaded picture and the available "filters" and "instructions". The idea of it is not really mature, since we have no idea where to start and what is possible to do. bye R.
Re: [PHP] image* Functions' Memory Usage
I recently made two commercial sites that used both GD and Imagick and i can share some wisdom i got from those projects. (both projects were "card" generators where users made their custom cards and but one had a fixed picture and users could add text and the other one allowed users to add their own picture with text) # Some functions of the GD library are VERY memory intensive. For example the image resizing. The resizing process is calling three functions to work and two of them are holding very large amounts of data within them. (the original image and the new image area you are going to put the resized image into, and then the 3rd functions resizes the image) # Basic GD library functions can be quite fast (and most if not all Imagick functions are fast if the image isn't too big) # Speed of both options are always affected by the size of the image being used. (Size in bytes, a 10x15 print quality card generated with a user selected image + text can take up to 30 seconds to generate) And yes thats an annoying generator to debug. # If you are going beyond simple things like adding text onto an image i recommend going with Imagick. # Imagick is a great system to use if you learn all the command lines and combinations, far superior to GD in many ways. # Complex Imagick functions (that works with all possible outcomes) can be VERY slow. # If you have the choice of running Imagick from the command line (installed onto the linux system) or running the Imagick PHPlib, go with the PHP library one (even though it looks like more overhead in code) since error reporting with the command line is close to none. # If you have the choice of the images being generated later (ie. by an admin of the system), go with that path always. (one of my systems does that and the other doesn't) and the problems with the end users on the image generating step are very hard to debug, since they usually describe the problems very badly.

It's not very hard to have JS add a few images and rotate/move them where ever you want. Plus there's not too many people that could make much sense from clear plain JS anyway. Flash is also a good bet. - Dan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For size, Flash would be your best bet, because everything is converted to a Vector but getting PHP to output to that is beyond my scope of knowledge, to be honest. I would probably do things with GD or ImageMagick, as you've already hinted. NetPBM might even be a viable alternate route. -- Daniel P.

[PHP] image* Functions' Memory Usage
Greetings, list. I have a web application that generates PNG images that are thousands of pixels high by thousands of pixels wide (using imagepng, etc.). The problem is this takes way too much memory, and the rest of the site becomes too slow. I'm working on something to cache the images, but some suggestions in the meantime would be great. Maybe ImageMagick is faster? Flash?Any suggestions? Thank you very much. - Casey -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Image functions: date?
I remember once coming across a bit of php code that displayed the "created" date of a jpeg image. I cannot find it, and I cannot find anything related to that in tfm. Can someone give me a push in the general direction? Thanks in advance.
