Hi Monte

Thanks for the info, though that is bad news. It had previously come
through on iOS ok - when picking a photo from the library, and also on
Android AFAIK.

Do we have any way of getting EXIF data from an image picked from an
image library using MobilePickPhoto?

Thanks again for the info!


iOS definitely strips EXIF data in some cases - perhaps it is just from 
photos taken with the camera or maybe it varies slightly with OS 
version.


The Android case you are observing is probably because the EXIF data is 
being stripped also.


Assuming you don't use a width/height argument on mobilePickPhoto then 
we just return the data which we are given with no processing at all - 
so you are getting what the OS wants you to get.


It might be that Samsung's camera app is a little more security 
conscious than other Android variants :(


Warmest Regards,

Mark.

Re: Small and strange problem

Hi Paul

Sorry for the delay in replying but my house has just been inundated (it 
happened on Monday and we are still clearing up! Worst flood in more than 40 
years in my French village). Anyway, the bug is registered as 22730. The 
problem is acknowledged - as I said in my submission, I’m not claiming my 
coding is correct, I’m just trying to show that the IDE doesn’t behave 
consistently in this instance.

Hi Graham,

Thank you for the update. Sorry to hear about the flood, I know from personal 
experience what that’s like so I really wish you and your family well, and that 
you can get your home and life back in to normal very soon..

Externals Question from Stack Overflow

[Devin Asay via use-livecode]

Hi all,

I came across a question on Stack Overflow from a sight-impaired user who is 
trying to figure out how to write and test a LiveCode external. I am pretty 
ignorant about externals in general, so I don’t think I can help in this case. 
But if anyone here feels inclined, I think it would help this user, and boost 
the number of responses to LC questions on Stack Overflow.

Regards,

Devin

Again not quite OT - freeware licence agreement?

[Graham Samuel via use-livecode]

I’ve built an iPhone app with LC which I intend to distribute without charge. 
Obviously I have to ban the user from reverse engineering, on-selling at a 
profit etc. This must be quite a common requirement, but my attempts to search 
for such a licence have proved rather confusing.

Has anyone got any recommendations? As usual, I’m having to provide this before 
Apple will even look at my app.

All of my iOS apps are free… all iOS apps on the Apple App Store fall under at

[Graham Samuel via use-livecode]

Thanks Randy, that’s really helpful. I am tempted to say I have now spent more 
time trying to get my Apple submission in shape than I did designing and coding 
my app in the first place - not really true when I consider the debugging 
problems I’ve had, but it was still a significant chunk. I guess it will be 
easier next time.

Re: Externals Question from Stack Overflow

[JB via use-livecode]

Part of the question was;

Can someone tell me how to obtain the pointer to g_external_name and 
g_external_table? How LiveCode knows it when it loads a DLL with my external? 
Is it possible to obtain the mentioned variables dinamically after DLL loads?


I do not think you can get any pointers in LiveCode and even if you did get a 
pointer
you could only use the address from within the program that obtained the 
pointer.  To
access pointers each external or program will use its own memory mapping so the
pointer itself is only good for the program providing the pointer info.  If you 
can access
the g_external in LiveCode then you can pass that info to your external using 
command
line arguments.

Re: LC9.6 Android EXIF image data issue

[Alan Stenhouse via use-livecode]

Thanks Mark and Monte for the info.

Had already stopped using the width/height specs and for photos from the 
library we had been getting EXIF info and still do in many cases (I think - 
more testing needed!), but as we can't do anything about what the OS gives us, 
I'll just slightly change the message for the user to inform them.

Thanks again, cheers

Atom Editor Help

[Peter Reid via use-livecode]

Hi, I’ve noticed that several of the LiveCode staff use the Atom text editor. 
Until now I’ve used BBEdit on the Mac and Notepad++ on the PC. I’m thinking of 
switching to Atom but need to be sure it can everything I need. For example, I 
have a typical piece of pre-process manipulation of text data that involves 
using several regular expressions. I’ve tried to find a macro in Atom that 
applies a series of find & replacement actions but have failed to find a 
solution. Can anyone provide a template macro for this?

Thanks

Before you give up on BBedit, try to get in touch with Thierry on the forums. 
He is a master of Regex and has a system of macros to make it work tightly with 
BBedit to replace the IDE.
