Some photo questions

Rgarner

Android Expert
Why are screenshots png and regulars are jpg? Also, why is it that sometimes the camera seems to take shots fast and others I have to wait for the blue line to travel around the circle? I hope I explained that right.
 
It's whatever came with the phone, a Samsung Galaxy S5. I'm a terrible photographer, but at least the screenshots generally come out well. Maybe some day I'll understand this stuff.
 
Thanks, if I can get this thing working again maybe I'll try that. I hope it's a free app and not too much real estate. What is the difference between jpg and png?
 
Different image formats. png (Portable Network Graphics) is a lossless bitmap compression format, intended as a higher-quality replacement for gif. It's suitable for things like icons and cartoons with low information density, but will produce a larger file when you have a lot of detail in it. jpeg is a lossy compression algorithm, so produces a smaller file but with some loss of information (how much depends on the chosen degree of compression).

So for a screenshot, which tends to have a relatively low information content (large areas of solid colour are common, and these can be compressed effectively with no loss) png is fine. Use it for a photo with a lot of fine detail in it and it will produce a much larger file size than a jpeg, and for most purposes the jpeg is good enough.
 
Why is it that the paid app still have adds?
You're sure it's the paid version showing ads? Mine most definitely does not. :o

I don't do ads--not on TV (that's what DVRs are for), not surfing the web on my computers (thank you AdBlock Plus!), and never, ever in an Android app.

If you go to the paid version in Play, does it say 'install' or what? What options does it give you?
 
What is a vector file? Does it beat all the rest? Is there an option for choosing which format(s) to use? I mean on the regular S5, no particular camera apps. Also, is jpg the same as jpeg?

Just looking at it in the store.

What is a vector file? Does it beat all the rest?
Yes, a svg/vector is considered amongst the best formats, but not suited for all use cases. What it offers above the rest is the ability to be stretched from a very small image to billboard size without losing visual integrity (ie. doesn't blur or distort when stretched). You can however save to other image formats from an svg.

Unlike some other formats, a vector is just a text file with code you can manipulate on the fly without an image editor.

Here is the code for a recent svg/vector I created. You can copy this code and save it with the ".svg" extension at the end then open it with your image viewer to see the image.

XML:
<?xml version="1.0" encoding="utf-8"?>

    <rect x="4.001" y="1" fill="#F2F2F2" width="49.998" height="4"/>
</g>
</svg>

As an app developer I use these in some areas of android for efficiency. The launcher icon for example usually requires 4-5 png images to accommodate multiple screen sizes. With a single svg I can accommodate all screen sizes since it can be stretched.
 
i guess what Rgarner is saying is that under the price for the app that it says "contains ads" which would suck if you paid for it and still get ads
Sorry, I'm at my doctor's office and for some bizarre reason, people keep pestering me! :D So I missed that. No, the paid version does not have ads. If it did, I'd have uninstalled and gotten a refund for it.
