It's Ubuntu Tahr that needs the patch.
Precisely. And the difference between the two is: Ubuntu inserted into GTK+2 a shitty module for perverting scrollbars, and Tahrpup left the module out.
Raspberry pi Jessie to test because I read that
it uses gtk3
GTK+3 is irrelevant.

Updated to version 3.49.04 :lol:

I noticed the following. I'm not sure if it's a bug or feature???

Steps:

1) open a gif
2) make an alpha channel with several levels of alpha
3) put the result in a clipboard
4) paste in a gif ----> only the highest level of alpha will paste in the window

5) paste in a 24 bit rgb image and all levels of alpha in the clipboard is
respected

I assume this is the regular behaviour of the gif format because only one color
is chosen to be transparent

All indexed images support only on-off transparency. Because alpha mixing would produce colors not existing within their palette.

Updated to version 3.49.06. Working well 8)

Does the PNG image format support on/off transparency as well
as an alpha layer (0 to 255 levels)?

Transparency in PNGs is a complicated story.
https://www.w3.org/TR/PNG/#11tRNS
https://www.w3.org/TR/PNG/#6Colour-values
Basically, the format was designed by control freaks, and combining color-key transparency with alpha is forbidden "because reasons". Same as combining alpha with indexed color (!).
mtPaint works around the latter limitation by writing its own chunk type, like for the other two utility channels. But the former one is just not worth the hassle; color-key is virtually never used with RGBA, and with indexed+alpha the problem does not arise.

But as image formats go, the only one where standard allows indexed+alpha is TIFF - and even there, not all readers honor it (GIMP does, however).

./configure release intl --prefix=/usr
make
make install

version 3.49.10 available
_______________________

An obscure bug... gifview shows the wrong animation...

Method:

Make a gif animation but save one of the layer images as png format.

Export an animation under 'File' menu --> however use the same name as another
gif animation previously made. You will see an error message
because of the png image, but gifview will show the previous animation.

PartedMagic on test bench at home. No MTpaint, i cannot do whithout this app. Downloaded from sourceforge debian package.
I just had to add libjasper and link to so4 libtiff
and MTpaint opened on my desktop.
That is a feed back, no action required.
Happy new year to photographics lovers, and all others, of course. :shock:

config issue?

#349 Post by sszindian »

installing- gtklp_1.3.1-0.1_amd64.deb - in the new Slacko64-6.9.6.4 mtpaint 3.49.12 does get mtpaint to 'print' however the 'config setup' for the print doesn't seem to respond to commands..eg,, tried placing a small clipart in the left/hand upper part of the image-setup, it still prints a FULL-PAGE graphic? yes... I saved my setup prior to printing!

The default 'kprint %f' is WAY to large to install besides many dependencies are missing.
