Ugh whoever invented the shit show that is the rotation on images is a cunt and I really want to strangle the bastard.

Its simple, most graphic programs, photo hosting sites  such as Imgur or even Photos in Windoze 10 contain a simple button to simply rotate the image for you, whats the problem?

[Specmaster]

(how the f do i rotate images? can't find any docs that work...)

GIMP?

Or, jpegtran. Or convert. That is not the point. The image contains orientation data that is ignored by something, so rotating the image by altering it will simply mess it up more.

Oh, wait.

treize:GP430LBN mansaxel$ rdjpgcom -v GP430LBN.jpeg
JPEG image is 5504w * 3096h, 3 color components, 8 bits per sample
JPEG process: Baseline

The rotation data was mangled by something; because exif says:

treize:GP430LBN mansaxel$ exif GP430LBN.jpeg
Corrupt data
The data provided does not follow the specification.
ExifLoader: The data supplied does not seem to contain EXIF data.
treize:GP430LBN mansaxel$

This is one of those situations when anyway you turn, your butt will point backwards..

Using Win 10?, use Photos, part of Win10, simple button top of screen to rotate and then save the image rotated into the correct plain?

Don't even need that in windows 10. Just right click:



Edit: couple of random photos from my jaunt out this evening ... walked all the way round the outside of Kew Gardens...

Brentford...



Richmond Lock...



Was definitely more fun than ebay listing 

[Specmaster]

Thats strange, been using win10 for years and I never noticed that option in the right click menu, thanks.

Edit, while you was walking, I was having another great BBQ 

[bd139]

Been there since build 1703 

[mansaxel]

Using Win 10?

Not if I can avoid it, no.   

Anyway, the thing isn't that I can't rotate an image. I've got like 5 tools on the computer that do such manipulations. The issue is that the camera phone was held upright and the image was intended to be vertical, not because the pixels come in one specific order, but, because there is orientation data in the picture saying which way it's to be rendered. This is much easier than letting the camera flip the picture. It simply makes sense to do it that way, but it needs to be done right.

Now, I cheated and rotated the image (and, yes it was caching, it works now), but I should not have to.

[Specmaster]

Change up to a better OS then 

[mansaxel]

Since I'm self-hosting my images .......

And what happens to them when you no longer can ?

They're gone, obviously. Not to toot my own horn too loudly here, but since that storage solution has been online continuously for the last 15 years (also while moving servers, it allows that) I think it's about as likely as a forum software to stay available. Unless I get hit by a bus, of course.

[bd139]

Either way the thread is almost entirely backed up on archive.org's wayback machine

[mansaxel]

Change up to a better OS then 

I did, 20 years ago. Only a short detour into the Swedish armed forces has made me use Windows the last years, but other than that I've managed to stay away from it, on the desktop, since. I do run a Samba-based Active Directory site at home, because family needs it. And I interact with windows machines at work, but I much rather have a Unix machine to type on. And the Apple ones are quite good Unices. For starters, they're not Linux.

[bd139]

Going to be honest here. Meant to mention this. I blasted that FreeBSD box after a couple of hours the other day because valgrind would not bloody work on it. Took an hour to compile (no packages) and then just dumped core

CentOS 8 ...

$ dnf install valgrind

Job done!

Don't get me started on OSX  . Loooong term OSX user. I'd rather use WSL on windows now.

Wish I had something to fix at the moment. Literally bored shitless.

Actually I'm probably going to list everything I've got that I was going to list for £10 or under on ebay seeing as that's got the same outcome as £1 listing weekends. Also only selling stuff I can ram in the post box over the road.

Edit: thinking about clearing out my TH component stock. I prefer working with SMD even on prototypes now.

Hopefully, tonight I'll finish up replacing my Tek 492's unobtanium fan with a modern fan. The twists are containing the noise (both electrical and mechanical), avoiding a current inrush blowing a £7(!) fuse, and temperature controlling it.

You could come and recap my hp53310a or hp8652b. Oh, actually, you can't.

I know what you mean about SMT vs PTH, but PTH is good for repairs and quick-and-dirty prototyping, especially with manhattan styles. The only component I've needed to buy for my 492's motor controller is a 22k thermistor.

Here's an interesting evolution of Manhattan-style construction I stumbled across the other day...

I've seen the concept before, but not the tool.

I suspect I'll stick to tinsnipping some PCB, and supergluing that onto the PCB acting as as the ground plane.

New addition to my TE-Stack: Hewlett Packard 5370b time interval counter:


Did a reasonable low offer that was accepted. Shipping plus customs fees will be more than the price though.   
I hope It'll go into my TE stack without problems and not into my repair stack.
I just hope the seller follows my plea for a strong cardboard package and strong padding on all sides..   

Now. all I can do is wait...

Am I a timenut? -No, I just need it to verify and calibrate my 5359A time synthesizer.

gimp ist your friend, man..      

What's wrong with you people?  I do not lack tools, I'm annoyed at the inability of orientation metadata to work in a portable fashion. 

Besides, using Gimp (which is a nice program, if you need that kind of editing power) to flip a JPEG 90° is like shooting fish in a barrel with a Gatling gun. Total overkill. (which I defined as "appropriate" upthread, I know!)

A much more appropriate solution is to use convert from the ImageMagick suite, like so:

convert input.jpeg -rotate 90 output.jpeg

With a small matter of programming you can flip an entire album if you so wish, without opening every file by hand.

You're right citing this.   

Next step: What tools do I need for verifying and calibrating the 5270b itself?      

[mnementh]

The pieces are coming together...


   
Spent half the morning arguing with Fusion to come up with this... it is a modification of the shell for my Pin Header Block mod so I can move forward with my PetsFang upgrade. More details here for anyone who gives a shit.

Well, actually it goes more like "Man with watch always knows what time it is. Man with two is never sure."

Which of course, y'all timenuts use as fodder for a whole herd, so as to be able to bell-curve your uncertainty factor into a statistical time-out.

I'm with you. I use the gimp regularly though. But not for just rotating images -that's done best with a small tool that does just that.

The Dremel bit is something like 30$. But you can find bunch of those really cheap from China.

I'll just average the value of my four different GPSDOs and am done. Hmm. perhaps add my two different rubidium oscillators to the equation. No, I'm not a timenut, I'm not a timenut, I'm not...
