Batch Export (animation)

Postby Mr. R » Fri Sep 03, 2010 1:18 pm

I wish to make an animation by with the batch exporter. Here are some problems:

  • I have onion skinned the animation by copying and pasting in place (without transparency).
  • Hiding other objects does not work once I select them all
  • I think I may need other plug-ins or programs

The images should be the same size. This is difficult when I use glowing effects or effects that expand because the "Selection" tab always wants to mess everything up. I assume that batch export works with the selection sizes (not page size).

Can anyone help me? It would be nice if there was a feature spread each image to frames or layers. I want to be able to do anything quickly by selecting all the images and performing actions.

Well I can go over to File > Export Bitmap...
And there's an option for batch export: "Batch export all selected objects."

yes - there's a short description in the manual and in the Release notes for Inkscape 0.46.

Wow, I never noticed that before -- awesome!

Well, I probably can't help you very much with your animation questions, but I can make a comment or 2. You know that Inkscape doesn't support animation yet, that's why you're exporting, right? The only program I know that can do vector animation is Synfig.

It does appear that the batch export exports selections rather than pages or anything else. Although I have not tested it yet. I also don't know what happens on the other side of the export -- iow, is each selection output in its own layer? Or are all the "frames" or selections just stacked up on one layer? Or do you get a separate image for each selection? Out of curiosity, do you know what you'll use to do the animation?
This is difficult when I use glowing effects or effects that expand because the "Selection" tab always wants to mess everything up.

I'm not sure exactly what you mean about the "selection tab" messing things up. I think you mean that those "frames" with a glow effect or blur or the like, will be larger than those without. But as long as the export only looks at selections, and as long as you have them all aligned exactly on top of each other, I think it should work. The one factor I'm not sure of is page size. If your page is the size of the smaller selections, so that the glow or blur falls outside the page border, it may not show up in your finished product. I don't know if the exporter only deals with selections, whether it completely ignores the page border....or not?? My guess is that you should make your page size to fit the larger glow/blur selections (or larger).

I'm not sure when Inkscape is set to support animation? I think I saw somewhere about Inkscape 1.0.....but that sounds so long to wait, lol.

  • batch export works on selected objects (not page size)
  • the selection frame of filtered objects is larger, otherwise effects like drop shadows would be cut off and not be part of the exported bitmap
  • if the exported bitmap images of differently sized vector objects need to be the same size, you could for example
    1. put each object inside a group together with a rectangle of the same size (as big as the largest selection bounding box of the objects you will select for batch export) and remove fill and stroke of the rectangle, so that it is not rendered in the exported bitmap, but makes every frame the same size
    2. otherwise you can change the selection frame (aka filter effects region) of filtered objects in the 'Filter General Settings' tab of the used filter effect in the Filter Editor dialog
