first of all I'm sure the answer is already out there somehow, but I can't seem to find it. All I ever find is "use FFMPEG" but how?
I can't really find any description on which functions to use or even what functions are there at all? I'm using C# and I have a RawH264IFrame which I need to convert to Bitmap or Image.
Can anyone tell me where to find the right information?
Thank you!
OpenH264Lib.NET is a C# wrapper for OpenH264 encoder/decoder. It can also save images from the video stream.
I've been looking around on the web for an answer to a perplexing problem. I'm trying to code a program in C# and I'm looking for a snippet of code that'll take any information a user would input, i.e using a textbox or a check box, and transfer said information onto a .PDF file that I've added as a resource.
Right now I'm using Visual Studio 2008 for my coding, any help would be appreciated.
You can use librairies to create PDF on the fly:
ITextSharp
PDF's are a proprietary format. PDF4Net is a pretty good library for merging information via XDF into PDF's, but you are going to have a lot of trouble trying to do this on your own natively.
i write a code using asp.net C# to generate a thumbnail when a video file selected using fileupload control, and display it in gridview. so, what i wanna do is when image in gridview was clicked, it should play the video corresponding to the video where the particular thumbnail is created without involving database?
There must be a Jquery plugin that solves the problem. I know there is many jQuery video plugins out there, just search for it. Why would you involve database? Can't you just include video files in your project and create a link from your images?
I dont know if this will solve your problem but worth checking out:
Simple jQuery video plugin
If you decide to use database I would suggest to keep it simple and use MySQL which is free and easy to setup.
I have a DIV container which has some text, background-image, image. I need to convert that whole DIV contents into image and save.
I have googled it around but could not find the perfect answer. some are giving answers that uses a windows application , but i need it on a web platform .
any help will be highly appreciated
From what I understood, you have to do that in the client side, so you should take a look at the toDataURL method of the canvas.
If you don't know, the canvas support text and image.
Example and little library at this link:
http://www.nihilogic.dk/labs/canvas2image/
http://html2canvas.hertzen.com/
Does't support IE though. Looks solid other than that.
This is possible, with modification to the code here http://html2canvas.hertzen.com/screenshots.html you could perform the required screenshot :)
I am using IKVM in a C# application so that I can use PDFBox to extract information from PDFs. Using PDFBox, I am able to extract images into PDXObjectImage. I need to get this PDXObjectImage into a System.Drawing.Image or System.Drawing.Bitmap. PDXObjectImage is easily converted to a java.awt.image.BufferedImage using pdxImage.getRGBImage(), but I don't know where to go from there.
I looked into it and saw that I could convert byte-by-byte, but I am too new to image programming to know how to do that. Any code snippets would be incredibly appreciated.
Thank you for your time!
If you are in C# code then you can use the method getBitmap() on java.awt.image.BufferedImage. This return a System.Drawing.Bitmap.
You can not call this method if you are on the Java side because it is hide. If you are in Java Code then only .NET refection should work.
