![]() ![]() A Powerful Tool Help Keep Your Mac in Top Condition Part 3. Read on to learn about the 8 legitimate options to fraps for Mac.Īrticle Guide Part 1. Yes, the good news is that there are fraps for Mac. While fraps are only available on Windows, there are options for Mac owners. Now, that doesn’t mean that Mac owners cannot record videos on their computers and laptop. Unfortunately, fraps are only available on Windows. It’s a superb teaching and learning tool. ![]() Teachers and students can also benefit from using fraps. It’s just good to have it in your computer. This would provide an exact match.It’s convenient to have fraps for Mac. This would be the correct(?) result of a function returning an alpha-blended image of the cursor.īut if you just want to use it in a screen capture program, you should check for the presence of the mask/image information and use it the same way Windows does when rendering the screen. This is fine for applying it to the screen, but if one wants a picture of what the icon usually looks like on a white background, you would have to do something like this: When the cursor is applied to the screen, the mask is AND'ed with the screen contents, then the cursor bitmap is XOR'ed with this result. This is because the cursor image is actually white, but the cursor mask is entirely white as well. When the cursor is an IBeam (like when over a text editor), the captured image is white, rather than black. Here is the C# implementation of the mouse capturing function: This information is easily retrieved using the GetIconInfo() function. Now, we have to get the Icon information so that we can get the hotspot position. If they are equal then we get the handle to the cursor icon using the CopyIcon () function that takes the hCursor member of the above filled structure. Then we check whether the cursor is visible or not, by checking for the equality of the flags member of the filled structure with the CURSOR_SHOWING constant. Don't forget to initialize the cbSize member of the structure before passing it as an argument. The function fills the CURSORINFO structure provided as a parameter. ![]() Then capture the mouse cursor bitmap as:įirst, get the cursor information using the Win32 GetCursorInfo().I have provided a simple function named CaptureDesktop() in the CaptureScreen.cs file that captures the screen bitmap as almost all the codes available over the internet do. First, get the bitmap of the screen using BitBlt().The solution to the problem of capturing the mouse cursor image with the desktop image is quite simple. Another way is to directly manipulate the desktop bitmap in the Video Memory if enough memory is available as provided by DirectDraw.īoth of these don’t provide us the facility to capture the mouse cursor image with the desktop image.This can be easily done using the BitBlt() or the StretchBlt() APIs provided by Win32. Do processing and then again blit it back to the Video Memory. Copy the desktop bitmap data from Video Memory to the System Memory.Windows always tracks mouse with a “Hot Spot”, the actual position seen by the Windows.Ĭurrently, there are two common ways to capture and manipulate the desktop image: ![]() Most of us think that the mouse cursor image is a part of the desktop display but actually it works on an upper layer over the desktop. First, we will discuss here what the actual problem is. Sometimes it becomes necessary to capture the mouse to see the whole activity of the hacked machine. You will see a lot of source code resources over the internet discussing how to take screenshots of the desktop or an area of the desktop but none of them discuss how to capture the mouse cursor bitmap with the screenshot. Also, it is used in non ethical applications like hacking applications, where a hacker can hack a computer using some malicious server application, and the server then frequently takes screenshots of the prey machine and sends them to the clients. Screen capturing is a very useful way of resource sharing as used in applications like Remote Desktop, Virtual Network Computing (VNC), where a user can access, view, and interact with a remote desktop as his own desktop. This article shows how you can capture screen images including the mouse cursor. ![]()
