<div dir="ltr">That's why I'd like to ensure the XML I create follows any standard that Digikam follows, if possible. Looking at the .picasa.ini files today confirmed my expectations that it'll be too difficult to convert the the non-destructive editing parameters to those that Digikam use. We have parameters like:<div><br></div><div>crop=rect64(fc40570fffff5ae)<br></div><div>filters=finetune2=1,0.526316,0.000000,0.000000,00000000,0.000000;<br></div><div>filters=unsharp2=1,3.000000;<br></div><div><br></div><div>I'll either leave the parameters out completely, and at best, try coping the Picasa params as is, just as a reference. Some clever nut can have a go at converting them later on using the DB or something!</div><div><br></div><div>I'll let you know how I go. I have to resurrect Eclipse and Java now. I had a quick look at writing a Kipi plug-in, but I couldn't work out the language and find doco on how to work with it. I probably need to look harder.</div><div><br></div><div>Cheers,</div><div><br></div><div>Simon</div></div><div class="gmail_extra"><br><div class="gmail_quote">On 10 February 2017 at 17:57, Gilles Caulier <span dir="ltr"><<a href="mailto:caulier.gilles@gmail.com" target="_blank">caulier.gilles@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">well parameters will populate the database with these information.<div><br></div><div>For the moment, it's just informative, but in the future, the goal is to be able to apply same filter on another image by copy and paste from GUI.</div><div><br></div><div>So, yes, it can be acceptable, but take a care.
