Can I Import Existing PDF Books Into Kindle For PC?

Crop An Inserted Image?

Image
Answer : You can crop your image with graphicx \documentclass{article} \usepackage{graphicx} \begin{document} % trim from left edge \includegraphics[trim={5cm 0 0 0},clip]{example-image-a} % trim from right edge \includegraphics[trim={0 0 5cm 0},clip]{example-image-a} \end{document} Use the trim option, which takes four space separated values. trim={<left> <lower> <right> <upper>} If you don’t give a unit, the package assumes bp i.e. big points to be the unit. After setting these values you must activate the cropping with clip=true or just clip . If you combine trim with height or something similar the image will be cropped and then resized. That means that the crop values must fit the original size. If found no solution to say crop to 50 % width. Update As Martin said in the comments you can use adjustbox to clip the image exactly by 50 %. Note that you must replace \includegraphics by \adjincludegraphics , to access the \width . \documentclass{artic

Could Using ALT + F4 To Close A Game Corrupt Save Data?

Image
Answer : As a programmer, both answers posted so far are incorrect. While it's possible to come up with a hypothetical situation in which pressing Alt + F4 would corrupt a save in progress, actually doing so would require the developers to quite deliberately go out of their way to screw up the saving system. From a coding perspective, the user pressing Alt + F4 does not "close the active window," nor does it "interrupt the program." What it does is cause Windows to place a WM_CLOSE message onto the program's event queue. That's all. The event queue, as the name indicates, is a queue of events for the program to process; this mostly consists of input from the user. At the heart of the code for essentially every program driven by external input, including games, is what's known as an event loop , which checks for input on the event queue, processes it, then repeats the last two steps in a loop forever until it's time to shut down.

7z File Manager Crashed And Left Temp Files Behind

Answer : Using the run command: ( WIN + R ) type "%TEMP%" and hit enter. This will bring up all the temp files stored on your PC through the user account you are on. 7-zip tells you the temp location it uses (extract from 7-zip.org/faq.html): 7-Zip doesn't know folder path of drop target. Only Windows Explorer knows exact drop target. And Windows Explorer needs files (drag source) as decompressed files on disk. So 7-Zip extracts files from archive to temp folder and then 7-Zip notifies Windows Explorer about paths of these temp files. Then Windows Explorer copies these files to drop target folder. To avoid temp file usage, you can use Extract command of 7-Zip or drag-and-drop from 7-Zip to 7-Zip. C:\Users\xxxxx\AppData\Local\Temp under windows 8.1 found MANY 7zipExxxx.tmp folders ...using up 16GB ! reboot did NOT help. Using CCleaner did NOT help. Manually looking at TEMP folders did NOT help. What I did was use WinDirStat to see all m
