Please take a look on the website http://quotes.rapidprototype.com.au/upload/ and upload STL File and press "Start Upload" button. You shall see the image of the object within the stl file as (.png) image. I want the same functionality(The image of the of the object within the stl file, rest of the work i can do). I want to get the image in .png or .jpr or .gif format as a 2D image. I want that the user can see the image of the object within the stl file that he/she uploads. I am using PHP.
Please assist me how can I achieve this using PHP. I shall be very thank full to you.
You could use ParaView www.paraview.org in the backend. This is free and reads stl as well as having the ability to save images. There is a python interface, so you can program it to do various things (starting by tracing your actions in the GUI). You can also give it options from the command line. ParaView has a web component, but it would probably be easier just to have PHP do a system call and look for the resulting image.
Test that it works on the command line before wrapping it in PHP

I'm building a PHP application that uses data from a web service. I add an image to a desktop application which then saves it to the web. The web service provides image URLs using the .ashx file extension. If I put one of these in an <img src="file.ashx?pictureId=abc123">, it displays as an image.
I want to store these images. I know they'll generally be .jpg files and can run file_get_contents on this and save it as such. However, if one was a .png, for example, I'd still be saving it with a .jpg extension, so it's an assumption I don't wish to make.
I've had a look at the raw string of characters of the file and cannot see any identifying features to tell me that it's a .jpg, apart from perhaps the clue that it was created in Photoshop. Nowhere does it say what kind of file it was originally, either extension or original filename.
Is there a way of finding the original filetype of a file contained within .ashx URL?
The question doesn't make any sense. Maybe the .ashx script generates the image on the fly out of nothing and there is no "original".
The correct question is: how to find the type of the image retrieved from the .ashx URL?
Save the image into a (temporary) file then use getimagesize() to find its type (GIF, JPEG, PNG etc) and choose the correct termination for its final file name.
my question is quite simple.
I have a Qt application with a Gui developed with QML.
My back-end side generates and saves jpg images in a folder called /images .
I am able to send from C++ to QML the strings holding the name of the images that I want to show. Sadly my QML Image object doesn't display anything.
It seems that if an image can be displayed only if it has been previously declared in the qml.qrc file.
Sadly, again, qrc files do not support wildcards yet!
https://bugreports.qt.io/browse/QTBUG-1400
Is there a workaround?
The name of the images are not fixed, they are generated with certain runtime values i.e. timestamp.
Thank you
By default it will search the image source in the qrc file. To make it go to the actual file system, prepend a file:/// to the path.
I'm wondering how it possible to extract images from .swf viewer?
Note that .swf file have not images itself.
For example I'm trying extract images from AVON catalogue from this link - http://avon.com.ua/PRSuite/eBrochure.page?index=1&cmpgnYrNr=201404&pageNo=0
Any ideas?
Best way is to put the .swf file in a decompiler for image extraction. Decompilers are smart enough to extract images for you and arrange them.
JPEXS Free Flash Decompiler is a more popular one
http://www.free-decompiler.com/flash/
You can extract other useful content from it as well.
Just download the .swf file from the website
A while back (like around 1999) I wrote a set of tools for Flash animations.
One of the tools is swf_dump which can be used to extract objects (i.e. write the objects in a form of script that sswf can nearly recompile...)
The tool also allows for extracting images that are inline (not downloaded dynamically by the flash animation, if so, anyway, you could as well download those images manually, you'd need the URL, though.)
The command line you can use is:
swf_dump -d my-animation.swf
Then your current folder will be littered with all the images that were found in the flash file. It extracts JPEGs and PNGs. The source can be compressed (SWF or CWF are supported.)
Now, you're on your own to compile that thing... The project is here and is in great need of updating (but Flash is kind of going out too...)

I want to draw/load pdf file which contain image, on the CStatic control in my VC++ project.
But, I don't know how to load pdf file on CStatic control.
I have searched a lot, but dint find any right direction.
In Mac, Its possible using specific function, but is there any way in Windows ?
Can you please suggest me any right direction...
Thanks in advance.
EDIT
I want to load image in PDF to CStatic, reason behind that I want to maintain image quality. Just load vector data of PDF image to on CStatic.
Please suggest ... !!!
There is no way to Show a PDF file inside a static control.
There are several ActiveX Controls that can show a PDF file. Also Adobe ships and AcroPdf ActiveX file that is free to use.
Here is a sample
If you just want to Show formatted data you can use an RTF-Control
Has anyone come up with a way to make thumbnail type previews for matlab figures in windows?
I'm getting tired of saving a .png along with the .fig file just so I know what was in it.
A useful helper for this would be a command line utility for windows that can be provided with an image file and told to use that as the basis for the preview for a given file.
I could write a helper function in matlab that saved the .fig, made a temporary image file, then pushed that into the thumbnail using the command line utility.
You can write a function in C++ that tells Windows how to generate thumbnails from your file.
This link explains about it. Check out the section about Thumbnail Image handler. This is the function that you will need to implement.
From what I managed to understand, the procedure is this:
Write a in-process COM server (DLL) that implements IThumbnailProvider interface
Put the DLL file somewhere on your computer.
Write an entry to the registry, by using the procedure described in this page.
That still leaves you with the problem of thumbnail extraction from .fig file. As far as I know, fig files are nothing but mat files. I am fairly sure that it is possible.
You will need a custom save function for all figures. It will print a thumbnail of the image (by using the print command), and save it inside the figure.
I know that it isn't much information, but it can help you to get started. You might as well ask someone who is highly proficient in COM technology for more help. Thus, I recommend adding a COM tag to the question.
Edit(1) - I've found a good tutorial on the subject:
