There may be PDF viewers not even handling bitmap tranparency, in which case vector elements in layers below the 'Bitmap' layer may not be rendered properly.We covered the use of the clip-path property for clipping using CSS, so it’s only natural that we now go over masking. You also need to repeat this if you have transparent objects at different depths. You need to repeat this operation each time you modify any of your transparent objects. This way, you have a combined Bitmap+Scalable Vector document: only the tranparent fill is not scalable, but it will be rendered correctly in PDF viewers. Turn off the viewing of layer transparent and on the layer bitmap before exporting your PDF. Move this copy to a new layer 'Bitmap' next to the layer 'Transparent' View only this layer and 'Edit > Make a bitmap copy' ( ALT- B) See my post at inkscape forum: ĮDIT: OK, thinking a little more of the problem, there's a better way:Ĭreate a layer 'Transparent' at the depth of the transparent objects, move transparent objects to this layer for any transparent solid colour object, duplicate it as many times as it overlays other objects, intersect each of these bits ( Ctrl+ *) with a duplicate of the overlaid object, and give the intersection the colour you obtain with the pipette in GIMP for this part of your drawing.Ī little of a hassle, isn't it? It should be scriptable.However, to the best of my knowledge, there is no automatic 'robust' way of exporting a scalable PDF with transparencies from inkscape. You can then convert to PDF, but this is not scalable anymore. The easy silly solution is to export bitmap, then the transparencies over solid objects are rendered. Use Adobe Acrobat or Okular (linux), these can render most of the type of transparencies in my experience (including gradients). Check that it is not rather your PDF reader that is unable to render transparency.
