Homebrew screenshot-merge: merge split screenshots right on the 3DS

[ihaveahax]

If you are so lazy and simply want to combine the top and bottom screens of the screenshots you take without using your computer, well here you go.

This is screenshot-merge and it does just that: merge every screenshot on your [micro]SD card. The result is a bunch of images in the folder "screenshots-merged". It only asks for confirmation and patience.

Get the latest release

This is obviously inspired by Screenshot Tool, a PC program by @RedHat but this comes with a few changes and limitations...

• Merged screenshots are in .bmp format. lpp-3ds can't save in .png (at least for right now). This does raise the filesize.
• There's no transparency on the sides of the bottom screenshots.
• Templates can't be used at the moment due to strange limitations that I'm looking into.

So, what are the advantages then?

• Done entirely on the 3DS, doesn't need a computer! Then (if you really want to) use a mobile device to transfer the screenshots (FTP? inserting SD card?) and upload using it.
• Only takes a few button presses and out comes images ready for uploading to a service like imgur! imgur will convert it to a .png.
• Supports ninjhax 2.x, NTR CFW, and Luma3DS Rosalina screenshots!

I figured the current downsides wouldn't bother most people, so I'm releasing it in the state that it's in. Enjoy!

Spoiler: Why not some screenshots I used with it?

Thanks to Rinnegatamante for Lua Player Plus, smealum for the screenshot feature of ninjhax 2.x, and Aurora Wright/TuxSH/other contributors on Luma3DS and Rosalina.

[gudenau]

A nice little tool for sure.

if you can tell me exactly how the format works then maybe. unfortunately I don't have a 9.2 or lower system, so...

Sounds cool. I wish I had thought of that. I actually wrote a program for PC that would merge all the images but this sounds a whole lot better.

Actually, there's an opensource screenshot plugin. Would be awesome if someone could make it merge by default and include TitleID and date/time in the screenshot.

top_XXXX.bmp and bot_XXXX.bmp where XXXX is a decimal number.

top_XXXX.bmp and bot_XXXX.bmp where XXXX is a decimal number.

what folder are they stored in?

 

[gudenau]

what folder are they stored in?

"/" unfortunately.

 

[ihaveahax]

"/" unfortunately.

I guess I should go try and work with that then. since I can't use NTR on anything I won't be able to test it.

in "top_XXXX.bmp", is XXXX always 4 digits or can it vary?

Always four, padded with zero.

Edit'
I swear that got auto-corrected.

can you (or anyone) please try this out and tell me how it goes?

https://github.com/ihaveamac/screenshot-merge/releases/tag/1.1NTRtest

I need someone who can actually use NTR to use it with the images it generates, because when I tried to convert a screenshot with an editor, this happened. I need to know if the images directly from NTR (or the plugin?) work fine.

 

[Lycan911]

I'll try this out! Does it merge the top screen images into a 3D image?

 

[ihaveahax]

no, it only uses the left image (for nh2.5). using the right screenshot would result in two separate merged images.

I'll give you a few screenshots when I get home. So in ~5 hours.

@ihaveamac I used this for NTR, success, but nothing in the screenshot-merged folder

the format is top_XXXX.bmp and bot_XXXX.bmp at the root of the SD card. if whatever you were using has a different format, please tell me. the final result are a bunch of files at /screenshots-merged/ntr/mrg_XXXX.bmp

Does saving the merged image/s as .bmp lower the quality of the image?

 

[ihaveahax]

Does saving the merged image/s as .bmp lower the quality of the image?

no, it's just a larger file size. it's a consistent filesize though (always 576054 bytes).

the only other option was jpeg, which of course has compression and not good for this.

@ihaveamac This is my root (made with the latest NTR):

looks like it's time for UI changes
