Add option to quickly preview result of filters
Last modified: 2018-05-24 10:45:15 UTC
Paint Shop Pro (7.0) has this option to quickly preview the result of different effects (filters). You can scroll through all the different filters (a bit like Plugin Details) and immediately see what the filter does (using it's defaults values) to the current image. This way you can quickly select an appropiate filter for the task on hand.
This is very similar to bug #52374 (and bug #68612) but having a separate, scrollable list of filters is a new feature so I will leave this one open as a separate bug report. The current plug-in system would probably make this preview too slow, because each plug-in is a separate program that has to be launched in order to produce the requested effect. I assume that Paint Shop Pro can do a quick preview because most of the filters are internal, but maybe I am wrong. So if we want to implement this quick preview, we have to choose between two options: - do the previews on a scaled-down (or cropped) version of the current image and accept the delays - use pre-rendered previews: that would be very fast but it could only be done for one hardcoded image (or maybe a small set of images), not for the image that the user is currently working on. The best solution may be to allow both: by default, the preview would display a pre-rendered image. But the user could select an option that would switch to a preview of the current image (calling each plug-in in the list).
The Effect Browser in Paint Shop Pro 8 is impressive, it produces thumbnails for every effect/filter. it uses a tree view based on the menu structure and generates previews for the currently selected branch (all the distort filters for example). (if this were to be added to the Gimp you would first need to implement the guts of a full thumbnail browser) by default it has a quick render option that generates slighly lower quality images. i couldn't find a good screenshot but an add on program called Plugin Commander is pretty simlar. some links, screenshot: http://thepluginsite.com/knowhow/tutorials/introduction/may03_4.jpg http://thepluginsite.com/products/picopro/index.htm are there any scripts or plugins that already exist that will create thumbnails of an image using various scripts? it seems like someone might have done something like that to make it easeir to create samples when producing documentation. (spent a while looking at the plugin registry but didn't see anything along these lines)
A treeview with thumbnails is implemented in a few lines of code. Is that the guts your are talking about? It shouldn't be too hard to implement this. Unless I missed something the PDB and GTK+ should provide everything that's needed.
Well, I missed something. The PDB does currently not provide a way to call a plug-in with default values. So this is basically depending on the PDB redesign that we hope to get done for GIMP 2.4.
