I'm using a script that I downloaded from google code to dynamically generate mosaic images with the GD library. The script seems a bit convoluted. I've messed around with it quite a bit, but I'm sort of confused since it's written in German and I don't speak deutsch. I know that in order for it to work, I need to have 121 different images. But, I'm not sure if they needs to be in the directory or in mysql. Does anyone have a clue as to how to use this? Or does anyone have some suggestions for a better script for generating mosaic images with the php GD library?
The script can be found here: http://code.google.com/p/phpmosaic/
Thanks,
Lance
The images you like to use as thumbnails have to be inside a directory. You must add them to the db using the methods
phpMosaicImageParser::parseImageFolder() or
phpMosaicImageParser::parseImage()
However: there is no fix number of required thumbnails, it will depend on the SourceImage and the used options how much thumbnails you'll need at least.

Im wondering does anyone know of any good tutorials that can help me learn to convert a human image to a cartoon using php image magick.
I have found this link, http://www.fmwconcepts.com/imagemagick/cartoon/
but there are two issue.
I'm not overly impressed with the results, I would imagine theres room for improvement
The script isnt PHP , but perhaps Ill have to learn to convert it myself and work from there.
I have another cartoonize class written in php that doesnt use image magick, but the results arent great, and I prefer image magick as it seems cleaner and faster.
Thank you
You can run bash shell scripts containing Imagemagick commands from PHP exec().
You might like this approach better, but I have no idea how they do it. See http://cartoon.pho.to/
I would like to build a PHP script to optimize images similarly to how PunyPNG or Kraken.io optimizes images. Essentially, I would need to be able to take .jpeg, .png, and .gif images and reduce their file size as much as possible without losing quality (or with minimal quality loss).
These services offer APIs, but I would like to avoid unnecessary costs, and I do not want to be limited by a specific number of daily uses.
Can this be done with something like ImageMagick? Is it even possible, or is it far too complicated?
talking about re-sizing images, they were never an issue, there are couple of tools that help you do that in bulk. Since you specifically say PHP, I am expecting you would be using it for displaying it on a page. for the very same purpose I wrote this little script not so long ago, which might be of some help to you.

Spatie has a decent package that gets updated regularly, I've been using for a while without problems:

I am trying to find some sort of plug-in for Ajax upload with a file preview. The image will be saved into a MySQL dataBase. Is that even possible? I guess all things are possible with certain requirements. Have you guys ever come across anything like that?
Let me tackle your question one bit at a time:
I am trying to find some sort of plug-in for Ajax upload...
BAM!
...with a file preview.
Yep, from the page above, although I might wonder why this is necessary and if it isn't remove it (I believe minimalist design is usually better) and go with fancy upload which seems to be more popular (sorry, I don't have much experience with ajax uploaders)
The image will be saved into a MySQL dataBase. Is that even possible?
Unfortunately, it is; you will have to use the blob data type (alternate tutorial). Personally though I would just create a directory and save the images there, because then you don't have to query MySQL every f***ing time you want to display the image (I would feel bad for hat server). In which case I suggest you use class.upload.php (I have good experiences with it), in conjunction with whatever ajax uploader you chose to use.
I guess all things are possible with certain requirements. Have you guys ever come across anything like that?
...yes
I also store the uploaded images in a directory and their names in the database.
I have developed a jQuery plugin that performs a dynamic upload of an image when it is selected, and previews it.
You can find a demo of the UploaderPreviewer plugin here:

Hope it is useful for you or for anyone with the same problem.
I am grabbing links to images and need to convert them on the fly to 72x108 to display on a website. The source images come from various resolutions, so cropping is required.
I know a moderate level of PHP so I can probably make something work for my needs, but was hoping for something that could be called by a url request. EG: mysite.com/thumbnail.php?src=http://anothersite.com/image.jpg&w=72&h=108
That would be ideal, it needs to support jpg/png.
Thanks in advance!
Here is a really handy script for processing and uploading images that's been a top google result for forever. I used it years ago and it was really easy to implement. Looks like it was just updated a couple weeks ago too :)

This may be overkill, but if you check out the examples you can see there's a lot you can do with it. If you don't use it for this project, it might be worthwhile to try out for the next one.
just read the image from the url with file_get_contents or using curl and use the php gd library to resize and crop the image as per your needs.
Go through the following links for more info:

In my site i m fetching my mysql data by using PHP. I want open that data in pdf file when i click pdf print button is it possible?
First of all, if you want a high quality professional product to do that. You want Prince XML
If you are looking into some open source tool to achieve something similar. You can look into this SO question.
You could prepare static PDF form file, that just fill it in with values using PHP's FDF module.
It depends which platform are you using. This would be an easy job if you are using Groovy on grails. There are plugins which facilitate pdf reporting like the jasper-plugin.

Check out jsPDF, an open-source library for generating PDF documents using nothing but JavaScript.
You can process the data with Apache FOP after transforming it to XML. (http://xmlgraphics.apache.org/fop/).
If your page is template based, you may create a template which produces xml output and process that. You'll have extremely well contol over the pdf construction. The tradeoff is that it is not a "plug this in and will work" solution, but I've done that and once its set up, works like charm.
I've used TCPDF in the past, it's a little kludgy but can definitely get the job done. (http://www.tecnick.com/public/code/cp_dpage.php?aiocp_dp=tcpdf)
The FPDF module in PHP is simple enough to get the data together. It is a safe option since you know what data you are passing out to the PDF engine. There are some streaming pdf options which can take in a bunch of html and then output that to pdf however they can get it quite wrong without you knowing.
I used, on Linux machines, WKHTMLTOIMAGE/WKHTMLTOPDF a number of times, on many projects. It workes like a charm, easy to use, just a script that you run.
