Pals,

I realized that gimp 2.3.15 (and some versions before) comes with zoom for previews. A very useful feature for what I want to develop (a noise reduction plugin).

I added a line 'gimp_zoom_preview_new (drawable);' that I got from http://developer.gimp.org/api/2.0/libgimp/GimpZoomPreview.html The plugin complies just fine, but when trying to run it in gimp 2.3.15 the plugin crashes with a message in the console:

: symbol lookup error: : undefined symbol: gimp_zoom_preview_new (gimp-2.3:21083): Gimp-Plug-In-WARNING **: gimp-2.3: plug_in_flush(): error: Broken pipe

So, what am I doing wrong?

Thanks!

Luis.

This is nothing to do with the zoom preview mate, you've got a blocked toilet!! I should call out a plumber, this could get messy. This often happens in older properties due to subsidence or nearby tree roots.

LOL !

sorry, had to laugh at the way that error came out. ;)

Sorry, I didn't understand your answer...

I just want to add zoom buttons to the preview window. I saw that many plugins use this. How to do it?

Thanks,

Luis.

Looks like the plug-in is not picking up recent enough versions of libgimpui. Try ldd on the executable.

Mmmm... I see...

I compiled gimp with './configure --prefix=/opt/gimp' for it not to touch my stable gimp 2.2 RPM install. I am compiling the plug-in with

/opt/gimp/bin/gimptool-2.0 --install

Thanks,

Luis.

You will probably have to set PKG_CONFIG_PATH to get this right.

I am doing something wrong... I tried with this command:

export PKG_CONFIG_PATH=/opt/gimp/lib/pkgconfig ; /opt/gimp/bin/gimp-2.3

and I still having the same error.

Thanks,

Luis.

gg,

I didn't get your joke at a first sight. English is not my language...

BTW, it was funny. :)

Yes, yes you are.

export PKG_CONFIG_PATH=/opt/gimp/lib/pkgconfig ; /opt/gimp/bin/gimp-2.3

and I still having the same error.

PKG_CONFIG_PATH only affects where stuff looks as it gets compiled. Also, you'd want to use PKG_CONFIG_PATH=/opt/gimp/lib/pkgconfig:$PKG_CONFIG_PATH, to keep the old stuff in there (assuming it's non-empty).

IIRC, you'd want to set $LD_LIBRARY_PATH=/opt/gimp/lib/ for runtime.

Interesting.
In fact, I didn't recompile GIMP, I only did a

export LD_LIBRARY_PATH=/opt/gimp/lib:$LD_LIBRARY_PATH

and the zoom preview worked! :)

However, I am getting many errors. One of them is due to the fact that I don't know how to retrieve the origin of the preview. For non-zoom previews, the funcion 'gimp_preview_get_position' gives you the origin. I wasn't able to find the correspoding one for zoom_preview (gimp_zoom_preview_get_position does not exist?!). Another one is that I don't know which is the equivalent to 'gimp_drawable_preview_draw_region' for zoom_preview.....

Thanks for the help, and the prompt answers!!!

Luis.

GimpZoomPreview is derived from GimpPreview so you can use all methods from GimpPreview.

Oops...

Another one is that I don't know which is the equivalent to 'gimp_drawable_preview_draw_region' for zoom_preview.....

Perhaps have a look at one of the many plug-ins in the source distribution that use a GimpZoomPreview...

I did it already.
And all of them implemented it with complicated code. No easy command. So, by your answer I understand that there is no 'gimp_zoom_preview_draw_region' equivalent (I wonder why...). I will try to understand what those codes do and implement then one.

Thanks,

Luis.
