You could have proved that point without being obnoxious (a 262,000 pixel wide image isn't necessary to demonstrate the problem). You do realize that touchscreens don’t have page up/down/home/end keys, meaning tons of manual scrolling just so you can feel smart about knowing that images can compress... :-- :-- (On the iPad, it's rendered vertically, and without scroll bars. Not sure why, since it renders fine on desktop Safari.) |

As a general note phones seem to suck at jpeg compression. Just re-saving the file on a PC makes it much smaller. |

I also suspect that many phones use hardware compression to save power, but this of course is often less space efficient and can't be updated. --- Quote from: blueskull on February 20, 2020, 01:00:05 pm ---Intentionally boasted file size, just for the deception that the phone has better image quality. Common trick used by phone manufacturers. --- End quote --- :-DD I think valid, reproducible testing would be required before making such absurd claims. |

There's no speed factor in quality-size trade off unless you use skimp on word length (use 16 bit arithmetic rather than 32 bit, etc.). Therefore, unlike iterative algorithms like MPEG4, there should not be any quality difference between a hardware encoder and a software encoder. --- End quote --- Hm, OK. --- Quote from: blueskull on February 20, 2020, 01:39:33 pm --- --- Quote from: Simon on February 20, 2020, 01:06:46 pm ---i agree but then Blueskull is notorious for living in an alternative reality. --- End quote --- Look, a new user in my ignore list. --- End quote --- Ignoring a forum mod/admin is a great way to get yourself banned, whether by announcing it like you did here, or by doing it silently and then not seeing a moderator's instructions to you in a reply you've hidden. |
