Before you can use an image as a texture with OpenGL, you first have to upload it. This takes the raw image information and sends it to the high-speed video memory of your graphics card. Images used as textures must be at least 64 64 pixels in size, and both the width and height must be a power of 2 (64, 128, 256, etc.). If your image isn t a power of 2, you should scale it to fit in the next power of 2 up. Listing 11-1 is a function that can calculate the next power of 2, given one of the dimensions. extract images from pdf using itextsharp in c# Extracting Image from Pdf fil using c# - MSDN - Microsoft

For instance, you might want to control volume and position and respond to events. To perform any of these tasks, you need to first define a few more interfaces. Add these at the form level, so they re accessible in all your event handlers: ' IBasicAudio exposes Volume and Balance properties. Private audio As QuartzTypeLib.IBasicAudio ' IMediaPosition exposes the CurrentPosition property. Private position As QuartzTypeLib.IMediaPosition ' IMediaEventEx allows you to receive events, including when playback stops. Private mEventEx As QuartzTypeLib.IMediaEventEx As with the IMediaControl interface, you can access all of these interfaces through the central FilgraphManager. You simply need to cast the object to the required interface before you load the file. You can place this code immediately after you create the FilgraphManager. code 128 asp.net, c# data matrix reader, c# gs1 128, java code 39 barcode, winforms pdf 417, asp.net ean 13 extract images from pdf file c# itextsharp How to extract images from PDF files using c# and itextsharp – Tipso ...

How i extract image from Pdg and display it in Image in Asp.net Webform. Another reason you might go to all the trouble of defining the additional interfaces is to measure the duration of a file and track the current position of playback. The IMediaPosition.Duration property retrieves the total length of the file (in seconds). Here s the code you could use to display the total duration of the file in hours, minutes, and seconds just before you start playing it: statusLabel1.Text = "Total: " & ConvertTimeToString(CInt(position.Duration)) This code employs the private ConvertTimeToString() method shown here: Private Function ConvertTimeToString(ByVal seconds As Integer) As String Dim hours As Integer = seconds \ 3600 Dim minutes As Integer = (seconds - (hours * 3600)) \ 60 seconds = seconds - (hours * 3600 + minutes * 60) Return String.Format("{0:D2}:{1:D2}:{2:D2}", hours, minutes, seconds) End Function Even better, to ensure the progress stays up-to-date as you play a file, you can add a simple timer that checks the IMediaPosition.Position property every 500 milliseconds and updates the status bar accordingly: Private Sub timerPosition_Tick(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles timer1.Tick If position IsNot Nothing Then statusLabel2.Text = "Current: " & _ ConvertTimeToString(CInt(position.CurrentPosition)) End If End Sub Now, just start the timer immediately after you start the playback: timerPosition.Start() and stop the timer before the playback is stopped or paused: timerPosition.Stop() _updColList[0] = "ID"; _updColList[1] = "NAME"; _updColList[2] = "PRICE"; _updColList[3] = "REMARKS"; _cmdObj.XmlSaveProperties.UpdateColumnsList = _updColList; After that, you need to define the properties outlined in Table 10-3.
