golden spiral

Another image made with the recent stone filter pack.

Somehow the dark stone texture looks a bit more like leather exported at high resolution.


Image was drawn in inkscape 0.92. The spiral itself is built up from linear gradiented circle sectors of 1 gon turns. The rainbow effect is made by a gradient map filter applied on a spiral made from gradient meshes, which got masked and clipped.


Will upload the svg sources from the intermediate steps soon.

newsprint filter

A base for various hatching and "newsprint" halftone filter effects.

Complex in inkscape's filter editor but easy to render, zooming doesn't lag.
If I could capture the structure behind would upload it as well, as it has a nice pattern.

It is based on the lightness values of the source object.
Maybe if there will be a decent filter editor in inkscape I'll get back to it and split the rgb channels instead.
But for now this filter is a bit too complex for the current editor.

gradient map filter pack -discrete-

The previous pack tweaked to have solid colours.
Can be used for the base of a hatching filter as well where image filter primitive is used instead of the flood fills.
On a side note this is the first time I used the table and discrete inputs for the component transfer filter primitive so probably I'll fix the previous "duotone" filters a bit sometime, which were using linear imputs, slope set to 10 twice in a row. This is a way more streamlined solution.

gradient map filter pack -table-

Revisiting the old idea again.
Took quite a while to rig this one.
The chain links between the filter primitives appears as an artistical image or an electrician plan to build a radio.

Takes advantage of the component transfer filter primitive's table input mode.
If you apply it on a raster image you can fine tune it by the slider for the component transfer right after the second colormatrix filter primitive.


All in all this filter pack is improved on its background.
-

Each square is filled with the same black to white linear gradient. Colours appear because flood fills are mapped over the source's lightness scale.
Each of the filters in thepack has the "gradient steps" distributed evenly, and their number goes from 1 to 16 in the pack.


Colours being used are inkscape's built in echo icon theme palette swatch.

sixties duotone turbulence megapack

Just finished this one.

Based on the previous turbulence base pack. All of the 64 colour combinations are added to pair with the previous duotone megapack.
Also made 64 separate sets of these filters, AND gradients too, however there is/was a bug in inkscape 0.91 preventing me from collecting the gradients in one file. It is already fixed by MC, when it will be part of the branch I'll make such a collection.

duotone turbulence base pack

Still on the same track as before.
Some turbulence filter variants, like these, but completed with a duotone tint.

sixties duotone filter megapack

Made a larger set from the previous pack. All variants are based on that older collection, which originated in a great collection at psychedelic-sixties.

gradient map filter pack

Sort of. There is no such thing as a gradient map filter primitive, so this one uses ten flood fills and compositing to map a gradient with ten steps over the object's luminancy.

For demonstrating purposes mostly, adjusting those gradients can make infinite variations.
Best applied on raster images, photographs.
