Batch tools, unsharp
Locked
 
|
Hi everyone,
I already asked about this problem, but got no answer. I will try again to explain what my problem is : The "tools - batch process", if I go to the "filter", and "unsharp", in the options, there are 4 settings that I can enter : Radius, Deviation, Percent, Threshold In the Imagemagick manuel, it says : threshold: The threshold, as a fraction of QuantumRange, needed to apply the difference amount (default 0.05). (ref : http://www.imagemagick.org/script/command-line-options.php?#unsharp) The problem is that I can only use integers as setting. It appears the same problem applies for the other parameters. In the page http://redskiesatnight.com/Articles/IMsharpen/ I can read : <quote> A typical call to convert might look something like the following: $ convert ... -unsharp 1.5x1.2+1.0+0.10 <input file> <output file> </quote> Obviously all parameters could be «NOT intergers», but in the batch-process, I can enter ONLY integers. Does anyone have an idea ? Is it a «bug» in Imagemagick, or in Digikam? Well, even in case of no answer, I want to express my gratitude to the team who gives us Digikam, which is a REAL tool. I use it day after day, and I enjoy it. > Hi, all. > > I am using Digikam (I've been using Digikam for about 6 months) on > Ubuntu (Gutsy), version is 0.92, and imagemagick is version (I > think) 6.2.4.5 > > First, I am suprised that there are TWO versions for the «unsharp > mask» function in Digikam. > > From the Image Editor -> Enhance -> sharpen -> Unsharp mask, where > I find a «a la Gimp» interface (three settings, Radius, Amount, > Threshold, and from Tools -> Batch process -> filter images > ->unsharp I get the «Imagemagick Style» version, with different > settings : Radius, Deviation, Percent, and Threshold. > > The Gimp version works OK.

Is it a ?bug? in Imagemagick, or in Digikam? Well, ImageMagick has slightly different attitude toward values. Almost everything there is in range 0-1 while in other programs it is usually 1-100 or even 1-1000. IM probably has more scientific attitude contrary to user friendliness everywhere else. It is not bug per se in either program. What is a bug for me is inability of digiKam to use non-integer values for radius. Other values are just different approach. Threshold in batch tool has range 0-20. I suppose it is just 0-1 in 0.05 steps. Usability bug definitely. You should file it in bugs.kde.org asking for uniformity between kipi and digiKam. BTW - for unsharp mask 1.0 application is quite strong, try it with 0.8. m. _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Yes, Mik,
To have coded originaly this plugins, the range is in interger and the parameters is passed to ImageMagick as a float after to have divided the value... Gilles

Good question. How can enter a radius of 0.8 ?

2007/10/17, Olivier Six <[hidden email]>: Good question. How can enter a radius of 0.8 ? You cannot do it. field is limited to integer values. Sorry. Note : with KDE4 port of kipi-plugins, i'm shared to port this plugin as well or to make anew one in digiKam core using all digiKam image editor filter (there are a lots of report about in bugzilla, especially to have auto color correction tools). I would to have alsoa a way to apply more than one operation over the image at the same time...

Just if somebody want to patch the tool in the right way, code is here : http://websvn.kde.org/branches/extragear/kde3/libs/kipi-plugins/batchprocessimages/filterimagesdialog.cpp?revision=670712&view=markup Look especially FilterImagesDialog::makeProcess() method, in Unsharp section... Note : sorry, but i have no more time to patch it. KDE4 port take me a while for all the rest of digiKam & co.

First major obstacle: I want to see string passed to convert added line kDebug() << Temp2 << endl; in proper place. Of course added #include <kdebug.h> in the beginning but make complains: filterimagesdialog.cpp:376: error: 'kDebug' was not declared in this scope make[1]: *** [filterimagesdialog.lo] Error 1 make[1]: Leaving directory `/home/mikolaj/kde/head/extragear/libs/kipi-plugins/batchprocessimages' make: *** [all-recursive] Error 1 ??? m. _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Mik,
with KDE3, use kdDebug() Gilles 2007/10/17, Mikolaj Machowski <[hidden email]>: Dnia Wednesday 17 of October 2007, Gilles Caulier napisał: _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |
