[PNGTranslator] can't open /system/documentation/diskusage/*.png images

[diver]

This is hrev39274 - gcc4.

The error is: "Could not load image! Either the file or an image translator for it does not exist."

note: this occurs only on gcc4.

[axeld]

Certainly works here. Any more info?

[diver]

Here is terminal output:

ShowImage /boot/system/documentation/diskusage/home.png
MessageImporter::Import() - error unflattening icon archive: Data is not a message
libpng error: [00][20][00][00]: invalid chunk type

Does a second version libpng* exist outside of /boot/system? Any oddities reported by checkfs?

[diver]

Nope, it's a freshly built image.

[axeld]

Looks like this file is corrupted on your drive. MD5 looks like this over here:

28f23b5988ca58f36e7fbe77bbcd64f4  /boot/system/documentation/diskusage/home.png

[diver]

Something still isn't right.
After rm -rf trunk/docs/apps/diskusage and image rebuild ShowImage still can't open this images, but Web+ has no problems opening them.
MD5 looks like yours.

[diver]

WonderBrush also opens them just fine.

[axeld]

Well something must be wrong at your side, since it's working fine here. And since the error comes from libpng.so, not ShowImage, maybe it's somehow using a different libpng.so version? I am using hrev39379.

FYI, these are the md5 for the two libpng.so.1.4 on my system:

~> md5sum /boot/system/lib/gcc2/libpng.so.1.4
cd6ac6d0cc651eda8b0110d422184ed5  /boot/system/lib/gcc2/libpng.so.1.4
~> md5sum /boot/system/lib/libpng.so.1.4
7a123283c75968a5ec845a75818c6171  /boot/system/lib/libpng.so.1.4

I get the same error with these PNGs. MD5 is the same. Opening in WonderBrush works but says:

libpng error: PNG unsigned integer out of range

Image is hrev39402, gcc4hybrid.

[diver]

​http://haiku-files.org/vmware/haiku-nightly-r39409-x86gcc4hybrid-vmware.zip also can't open them.

[diver]

... but ​http://haiku-files.org/vmware/haiku-nightly-r39409-x86gcc2hybrid-vmware.zip opens them.
So it seems GCC4 only issue.

[mmadia]

Running the ShowImage binary from hrev39395-gcc4 inside hrev39385-gcc2hybrid exhibits the issue (comment:3) as well.

[axeld]

Then it's at least sure there is indeed something wrong, it's just the question where.

These two PNGs also do not work here (hrev39605), but they are just destroyed. They cannot be opened at my normal OS, too.

still seeing trouble with jpegs only at 39943 gcc2 hybrid

[luroh]

Still with us in nightly hrev40715, gcc4.

Replying to stargatefan:

Likely not related to this bug, please file a new ticket if the problem still exists.

Haiku revision: hrev42211 not a bug. There are 4 libpng.so and 4 libpng.so.1.4 files in system or develop directories.And there is no problem with opening png files . System: Haiku hrev1-alpha3 on VMware workstation 8 on windows 7 32 bit

[humdinger]

ShowImage shows those PNGs, though still showing "libpng error: PNG unsigned integer out of range". Closing as fixed anyway. (As aside: I don't see a reason to keep /boot/system/documentation/diskusage at all...)

[diver]

This is gcc4 only issue which is still here. I think it should be reopened.

[humdinger]

Ah, didn't know that... reopened then.

[diver]

Still with us in hrev44676.

[pulkomandy]

gcc4-only, moving out of R1.

[diver]

Interestingly, on x86_64 these images crash ShowImage.

[pulkomandy]

Can't we just run these images through pngcrush or optipng to re-encode them? I think that would fix the issue. Unless we can find other images elsewhere triggering the same problem.

[diver]

That might be an option, yes. However Web+ and Qt apps have no problem opening those.

[pulkomandy]

Fixed in hrev51297:

• Fixed the crash in ShowImage. Failing to open files is ok, crashing is not.
• Replaced the images with modern and hopefully correct PNGs.
