everyon my question is how to convert jpg to ico file, or how to make big icon with high resolution like in windows 7 icon, for example from games Purble place, that can be show at desktop in big view?
Links from tutorials, examples and functions from c++ will be higly respect ..:)
If you insist on using some form of automation, then have a look at imagemagick --- it's a cross-platform command-line utility that can do file conversions and all sorts of cool image manipulation.

I am currently coding a winrate statistics menu for League of Legends (which got approved) using ImGui and I wonder if it is possible to display a GIF or MP4 on the Menu as a Preview or Usage Tutorial not from File/Memory but from an URL as I want to keep the File as small as possible for now.
You probably would have to use a filestream, downloading the file to tmp and then displaying it as a Texture?
I found a similar question, and I wonder if something since then has changed:
https://github.com/ocornut/imgui/issues/2680
Is it still required to use an additional GIF loader?
Are there any easy ways now to achieve that?
I am a bit (new) to ImGui and would be very happy about any reference source code (not to copy paste, just to learn it).
Thanks for any help :).
the heading says it all actually:
i want to convert a pdf file into several jpg images. This is to be a part of a software coded in c++ (I'm using Qt for my interface if that matters... :)
Preferably i want the images output to be 72 dpi.
Is there a easy way to do this?
Please comment if you need any more information form me, I'm grateful for any help, tips or answer!
Take pdf2image utility, and run it from you program, collecting its output files.
If you really need single executable (why?) — take a look at its source, and rip everything from it.
You should try to use poppler (or xpdf). You'll have full control of the rendering resolution and can take advantage of image output devices (ImageOutputDev) which will render pages to a framebuffer.Saving this framebuffer to jpeg with libjpeg is ,then , pretty straightforward.
I am a beginner with regards to Qt. I need code to browse an image which is stored in system and add the selected image file (jpeg only) during run time.
Take a look at QFileDialog::getOpenFileName() for getting a file path to open.
EDIT
The second part of your question is not clear. There are a variety of ways to display an image in Qt. You have to be more specific.
I'm modifying a C++ application and I'd like to add the ability to print and existing PDF using the MFC printing logic (OnPrint...)
Is there any method to print a PDF into the MFC? Now I'm converting the PDF to a BMP but sometimes the quality is not so great.
Unless something's changed recently you need a 3rd party library to print PDF files. One direction you can take is to convert to PS and then use ghostscript to translate to printer speak. Ghostscript also has the power to convert PDF to PS.
I don't think MFC's own printing logic will work.
Adobe distributes a PDF ActiveX control (primarily for viewing PDFs in IE) that can also be hosted in an MFC application. It includes the following methods: Print, PrintAll, PrintAllFit, PrintPages, PrintPagesFit and PrintWithDialog.
I am doing a project in C++ and I want to open PDF files. How can I do it in turbo c++? Do I have to switch to another IDE?
Edited:
I am doing an "E-book management" in c++. After managing the software i wanted to open pdf file through my program and do no access adobe reader or aome other. Sorry for incomplete question.
You can add PDF support to your application with TechSoft's PDF library. Which IDE you use shouldn't matter.
If your intention is to open the PDF for viewing (like you probably do with your PDF viewer, e.g. Acrobat Reader), and not to open the file programmically, you cannot do it in Turbo C++ IDE.
Try opening the IDE in non-full-screen window, and you will be able to see the IDE and the PDF (in the Acrobat Reader) at the same time.
The Poppler library is a C++ library for rendering PDFs to any arbitrary format, whether to screen or image. It's very easy to extend, and I wrote a program for rendering PDFs to a custom image format in about 150 lines, in a little under 5 hours - and most of that work was in exporting the custom image format. A simple renderer came in under 50 lines and took me less than an hour to write.
