Problem to export SWF File

[fmanzano]

I'm using Salasaga on a Debian 5.0 Lenny OS. Salasaga stars without problem... but when I try to export to SWF sudenly  the salasaga interface shutdown (close) and in the shell (terminal) I get:

(salasaga:7057): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width > 0' failed
PNG images must be translated into DBL files for now

some idea?

Hmmm, that sound different.

Parts of the message its giving are helpful.  For example, "assertion `dest_width > 0' failed".  That means the code in Salasaga is expecting an exported image to have an output width greater than 0, but for some unknown reason it's either 0 or negative.

Not sure why (yet).

Need to know the basic information in order to be able to look into it.

• Which version of Salasaga are you using?  (Help -> About)
• Which version of the Ming library are you using? (libming)

?

Hi!! Thank you for answer.

Here is the information:
Salasaga Version: v0.8.0-alpha5
libming Version: Ming-0.3.0

Regards.-

I'll be waiting for yours comments.

Ok, that all sounds fine.

Are you ok to either attach the project file to this message (preferred), or email it to me directly (justin@salasaga.org)?

That should let me directly try to trigger the same problem, then find out what's going on.

Btw, which output resolution are you trying to export to that's crashing?  Guessing "all of them", but asking in case it's something specific.



PS - Am leaving for work now, so won't be able to look at this until after then.

This problem happend with all my projects... and even when I'm trying to open a project, salasaga's interface shutdown (close).

A similar message:

Code:

(salasaga:27542): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width > 0' failed

I red about that the resolution is a common problem and I change it to 800x600... same result. I really prefere something like 1024x700

You are going to work and I'm leaving LOL. I'll write you at home. OK.

Regards

PS: My native lenguage is spanish.-

No worries.

Really need an example project file from you, because it'll help me figure out what's going on.

It doesn't happen with the project files my system creates... so it could be all kinds of different things (including language support, etc). 

[fmanzano]

Send you the project... Done. 

Thank you for your support! 

Regards...

[JustinClift]

No worries.

Replied to your email yesterday, but haven't seen a response yet.

Maybe it got caught by your junk filter?  .swf and .html files were attached, so not sure if that would have made a difference.

Hi, Justin -

I'm having exactly the same problem; Salasaga crashes when asked to export project as Flash, with 'failed assertion' as a message. I've gone a bit farther and ran 'strace' on it, and the output shows Salasaga endlessly trying to read the DejaVuSans.fdb file:

open("//usr/share/salasaga/font_outline/DejaVuSans.fdb", O_RDONLY) = 20

...

read(20, ""..., 4096)                   = 0

This last line repeats 391,000+ times before Salasaga gives up:

fstat64(1, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 8), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb5108000
writev(14, [{"GIOP\1\2\1\5\0\0\0\0"..., 12}], 1) = 12
close(14)                               = 0
writev(12, [{"GIOP\1\2\1\5\0\0\0\0"..., 12}], 1) = 12
close(12)                               = 0
close(11)                               = 0
close(10)                               = 0
unlink("/tmp/orbit-ben/linc-515d-0-32fa1cf75b3fe") = 0
close(13)                               = 0
write(1, "failed assertion"..., 16)     = 16
exit_group(0)                           = ?

I've also attached the project file.

Thanks for any help you can provide, and I'd be glad to help you troubleshoot in whatever way I can!
