JPEG System.takeScreenshot doesn't work

[Creckeryop]

0 bytes file appears

A possible solution is to move from sceJpegEncoder to libjpeg usage for this. (lpp-3ds code can be taken into account for a solution: https://github.com/Rinnegatamante/lpp-3ds/blob/master/source/luaSystem.cpp#L314-L356 + https://github.com/Rinnegatamante/lpp-3ds/blob/9b09073becb161299045534ed3ea4b3e976c1c34/source/include/graphics/Graphics.cpp#L1557-L1581

sorry for false info, this function works properly.

0 bytes file appears in the next situations:

• takeScreenshot before first cycle of Graphics.initBlend() Graphics.termBlend();
• fast closing application (while takeScreenshot is working).

  Steps to prevent 0 byte screenshot in your app:

• lock Home button while takeScreenshot is active;
• be sure that takeScreenshot is called after at least one cycle of Graphics.initBlend() Graphics.termBlend(). Sorry again.
