HP Scan and Capture for Windows 10 is straightforward to use. When activated, it scans for devices within the range including wireless printers, scanners, and any devices connected to a local network. You can scan documents or images in, then do some basic editing. Crop images or rotate them before saving them as JPEG files.
Also, you can save text documents as PDF files, either making each scanned page its own PDF or combining several into a multi-page file. You can change the order of scanned pages before combining them. However, it is important to note that it only serves bare-bones scanning utility, with limited control over the final output. It's not a real image editing or document management application, and it isn't meant to be one.
With its fresh update, the interface is now made more user-friendly for much simpler scanning and editing. Automatic device scanning is added, as well. This feature will help you to turn your documents and images into PDFs quickly and easily. As mentioned, you can fully use this program free-of-charge as long as you have an HP scanner or scanner/printer combo.
If you are looking for an HP scanning device on Windows 10, HP Scan and Capture for Windows 10 is a useful tool especially if you own an HP scanner or scanner/printer devices. With this, you will be able to effortlessly scan any of your files in the highest quality output possible. It also offers several editing features, but only the basic ones. Nevertheless, this is still handy to have.
It didn't show up as a regular file (still don't know where the exe is on computer). Didn't show up as new under all programs on classic start menu which I use since the Win10 "Most Used " left side is worthless to me vs programs I want to have there... Also was not showing up as a new tile when switch to windows start (using the windows key). HOWEVER when in windows 10 menu found it by using the alphabetical look up.
When you're using a Microsoft 365 program with Windows, there are two ways to copy the contents of what you see on your screen (commonly referred to as a "screenshot" or "screen capture"). You can use the Snipping Tool or the PRINT SCREEN key.
Pressing PRINT SCREEN captures an image of your entire screen and copies it to the Clipboard in your computer's memory. You can then paste (CTRL+V) the image into a document, email message, or other file.
I want to write a screencasting program for the Windows platform, but am unsure of how to capture the screen. The only method I'm aware of is to use GDI, but I'm curious whether there are other ways to go about this, and, if there are, which incurs the least overhead? Speed is a priority.
Edit: I came across this article: Various methods for capturing the screen. It has introduced me to the Windows Media API way of doing it and the DirectX way of doing it. It mentions in the Conclusion that disabling hardware acceleration could drastically improve the performance of the capture application. I'm curious as to why this is. Could anyone fill in the missing blanks for me?
Edit: I read that screencasting programs such as Camtasia use their own capture driver. Could someone give me an in-depth explanation on how it works, and why it is faster? I may also need guidance on implementing something like that, but I'm sure there is existing documentation anyway.
For reference, Open Broadcaster Software implements something like this as part of their "dc_capture" method, although rather than creating the destination context hDest using CreateCompatibleDC they use an IDXGISurface1, which works with DirectX 10+. If there is no support for this they fall back to CreateCompatibleDC.
Once you have the pixels in hDest/hbDesktop, you still need to save it to a file, but if you're doing screen capture then I would think you would want to buffer a certain number of them in memory and save to the video file in chunks, so I will not point to code for saving a static image to disk.
I wrote a video capture software, similar to FRAPS for DirectX applications. The source code is available and my article explains the general technique. Look at -direct3d-applications-to-capture-video-and-calculate-frames-per-second/
Another approach to recording screencasts could be to write a Mirror Driver. According to Wikipedia: When video mirroring is active, each time the system draws to the primary video device at a location inside the mirrored area, a copy of the draw operation is executed on the mirrored video device in real-time. See mirror drivers at MSDN: -us/library/windows/hardware/ff568315(v=vs.85).aspx.
I was dismayed to find that GDI performs about 2.5x faster. After 100 trials capturing my dual monitor display, the GDI implementation averaged 0.65s per screen capture, while the DirectX method averaged 1.72s. So GDI is definitely faster than GetFrontBuffer, according to my tests.
One nice feature it has for screencasting is that it detects window movement, so you can transmit block deltas when windows get moved around, instead of raw pixels. Also, it tells you which rectangles have changed, from one frame to the next.
And the one you mentioned (fraps hooking into the D3D dll's) is probably the only way for D3D applications, but won't work with Windows XP desktop capture. So now I just wish there were a fraps equivalent speed-wise for normal desktop windows...anybody?
I realize the following suggestion doesn't answer your question, but the simplest method I have found to capture a rapidly-changing DirectX view, is to plug a video camera into the S-video port of the video card, and record the images as a movie. Then transfer the video from the camera back to an MPG, WMV, AVI etc. file on the computer.
In windows 10, I can use the Snipping Tool or Snip & Sketch to snip a part my screen (basically a screenshot + crop to selection). I would like to snip the same part of the screen after I perform some other operation in another application that changes what's shown in that part of the screen. I have to manually perform this operation for example by pressing some button in another application.
One way I can think of doing this is to screen capture that region (for example using LICEcap) then dig in to find the desired frames. This is non-ideal because my intermediate operation could take a long time, there might be quality issues with the extracted frames, and it's a lot of work to use some tool to extract frames.
One fairly straightforward way to do this is to separate the capture operation from the crop operation. Capture either the entire screen with Ctrl+PrnScr or a window with Alt+PrnScr; paste into an image editor which supports layers1; repeat until you have all of the captures as layers of a single image; then crop the image and save the layers out one by one.
Similar to the Print Screen methods also posted, you could use the Window snip (from Snipping tool). Then as long as the window stays the same size you'll always keep the same section of the screen selected. Alternatively, if window changes size, you can put a larger application in the background and select that with the 'Window Snip', which will capture the screen and all windows in-front of it.
About 2 years ago a coworker of mine posed the same question that you had and provided a packet capture for me. Before I could even review the packet capture they had wiped out the machines settings and when reconfigured, without DNS, they noticed that the problem went away. I never really dug into the pcap because this was fine for the customer, problelm solved.
I know enough about packet analysis to find out what the root cause of a problem is most of the time, so I had a look at those 2 packet captures side by side. What I saw in them was identical. Repeated reverse DNS lookups that continually failed causing scans to deliver slowly.
If you are interested in learning more through personal analysis you can take a packet capture using the built-in network troubleshooting log function found in the security section of the Xerox Embedded Web Server. Take a capture of the scanning process with your previous DNS servers configured and one with the new ones and take a look at the difference in Wireshark.
I would need to see a network troubleshooting log (packet capture) to verify that I'm correct, but in my experience this is usually caused by failed reverse DNS lookups. An easy test to validate my assumption is to remove any DNS entries from the machines TCP/IP settings and retest scanning. Of course you'll need to have your scan configuration setup via IP and not hostname since we've removed DNS servers. If it works normally without DNS servers entered on the Xerox and you want to have DNS servers configured on the device then you'll need to look into your server side configuration and make sure that reverse dns zones and PTR's that are properly configured so the queries that the machine makes can complete.
