Failed to load image .png in 0.9.0-rc1

[Richard Taylor-16]

Hi

I have just rebuilt my machine and installed 0.9.0-rc1 and for some reason I
can not view png files.

When I open a png file in the "Image Editor" or in "Showfoto" I get the error:

  Failed to load image <filename>.png

On the console I see:

 QFile::open: No file name specified
 QFile::open: No file name specified
 showfoto: WARNING: Failed to load image <filename>.png
 showfoto: WARNING: [Digikam::DImg* Digikam::DImgInterface::getImg()] d->image  
is NULL

I do get the thumbnail displayed and I get all the EXIF meta data displayed.

Is this a qt problem? I am not sure which element of the system is causing
this problem. Inkscape, scribus and gimp all display png images fine.

System details:

 digikam-0.9.0-rc1
 kde-3.5.2
 qt-4.1.4-r2
 gcc-4.1.1
 glibc-2.4-r3
 2.6.17-gentoo-r8 i686

Any pointers would be very much appreciated.

Regards

Richard

Hi Richard,

Just check libpng sahred library. digikam PNG image loader use it.

Also, you can send me in private a PNG file sample to check if all is ok.

Hi Gilles,

Thanks for the superfast response.

I have rebuilt and upgraded from libpng 1.2.12-r1- to 1.2.13 but still get the
same error, would you expect me to have to rebuild digikam too?

Link to sample image on its way directly to you.

Regards

Richard

Of course. To be sure, clean up digikam before (make disclean) and re-compile
all (make -f Makefile.cvs; ./configure; make ...)

I am glad that you have a good memory :-)

I have rebuilt both digikam and digikamimageplugins but I am still getting the
same error. (These build are being done by re-emerging the gentoo ebuild,
which will start a new build from scratch). Anything else I can try?

no, no, no. have you recieve my mail in private ? Your PNG test image is not
PNG file, but a JPEG file. This is why digiKam PNG image loader cannot read
it.

Just change file extension from .png to .jpg...
