This article、This is the developer's personal impressions.。Please read only if you are interested.。
The world is buzzing with talk about iPhone 6 and iOS 8、We have finally released a new app。
Honestly, this app was more difficult than I expected.。There was an incident where the development machine Mac broke during the process.、While doing other things,、It took more than half a year from the time I came up with the idea to the time I released it.。
The beginning was simple。I personally don't post much on SNS.、I have a photo I want to send、I didn't want to show part of the photo to the public.、I was looking for an app to easily blur that part.。
The iPhone is fully loaded with apps.、You'll soon find a free and easy app to blur.。I also thought it would be nice to be able to delete the shooting date and time and GPS information, so I looked for it...
The blurring process is not easy to use and you cannot blur it as you imagined.、While editing the blur, a full-page advertisement suddenly appears and gets in the way.、It has a lot of functions such as brush shape and pattern selection, so you can do anything.、I don't really know how to blur it.、When I tried to save the edited image, it was resized to a smaller size than originally.、The image quality of the unblurred parts is poor.、Also, the shooting date and time and GPS information have been deleted.、You may have no idea what information was originally included or what information was deleted.、It was all like that。
Huh?、Something like this? Well then、Maybe I should make it myself?。It's not easy if you just blur the place you traced with your finger.?Also, check and delete Exif information such as shooting date and time and GPS information.。If this is the case, I think we can release it in a month at the earliest.?
And it was this development began in the wishful thinking...
in、For now, the process of tracing an iPhone screenshot with your finger and blurring it is、Done in a few days。Whoa、I thought I could do this right away, so next time I tried to blur a photo taken with my iPhone's camera...。eating up too much memory、Instead of the app crashing, the device suddenly reset.。
This is where I learned for the first time how difficult this type of app is.。Since iPhone photos have 8 million pixels, 1 pixel is 4 bytes, which is 32MB of data.。If I update this with blur processing in real time at the same time as the touch, the iPhone won't have the performance.。That's why I realized that everyone is editing with lower quality.。everyone、``Is this what it is??I'm sorry for saying that.。
If、Place the display image in front of the actual image.、While touching, the display image will be blurred.、Shouldn't the actual image be blurred in the background??That's it、Also, when I started implementing it with a double layer structure thinking lightly, the processing became several times more difficult.(>_<)。Even if it is processed in the background、If you process images of more than 1M pixels at a time, operation will become unstable due to insufficient memory.、The traced area is divided into 1M pixel areas and blurred little by little.。To find this appropriate size, we process it while solving two-dimensional equations.、Solve math shape problems every day、100It felt like I had to stay and do extra lessons all the time until I got the points.。It took me about 2 months to finally get the tuning to my satisfaction.、I'm a little tired、This development has been dormant for a while.。
after that、I suddenly thought of it、If you add a little color at the start of the touch when blurring、Wouldn't it feel like it could be erased??That's what I thought and tried it.、I named it ``Photo Eraser'' because it erases nicely.、I finished it。
I would say finishing、There are many functions left to be done, including Undo/Redo functions.、Menu that pops up at the touch point、Resize function、Trim function、Exif information display/edit function、tutorial etc.、In the end, it took two months just for those things.。There were other things I wanted to do.、Schedule the next session、I managed to submit a review request to Apple a week before the iPhone 6 was announced.。but、There seems to be a rush of applications at this time of year.、Today I finally got it reviewed by Apple and was able to release it.。(It took 10 days after requesting a review.。)
in the end、I just want to check and delete any privacy information when sending images.、Well, I'm having a lot of trouble.。It looks like the waterfowl is swimming comfortably on the surface of the water, but underwater it feels like they are desperately trying to maintain their balance while paddling in the water.。
Well、Don't worry about that、No need to edit or blur、When sending images somewhere、Please check the privacy information using "Photo Eraser".!
