It's the king of Artistic filters. It can do what Cubism and Apply
Canvas do and much more. It gives your image the look of a painting.
All is going as if your image was painted again on a paper and with a
brush you'd have chosen. It works on the active layer or selection.

You can find this filter via the image menu through

Parameter Settings
-
Preview
-
All your setting changes will appear in the Preview without
affecting the image until you click on OK.
The Update button refreshes the preview
window (it is not automatic, Gimpressionist has so much work
to do!), and the Reset button reverts to
the original image.
-
Presets
-
GIMPressionist has a lot of parameters. When combined, they
give an astronomical number of possibilities. So, it is important,
when an interesting preset has been found, to save it and also to
send it to the plugin author if exceptional. Per contra, the
intricacy of all these parameters makes difficult understanding
and foreseeing how each one works.
-
Save Current: Save current parameters.
You can give a name in the input box on the left and a short
description in the dialog that appear.
-
Apply: Load the parameters of the
selected preset in the list.
-
Delete: Delete the selected preset. You
can delete only the presets you have created.
-
Refresh: Update the preset list.
-
Paper tab
-
This tab concerns the texture of the canvas your image will be
painted on. You have a list of textures and a
Preview for the selected texture. A
description is displayed on the right for every texture when
selected.
-
Invert
-
Inverts the paper texture: what was a hollow turns to a bump
and vice-versa.
-
Overlay
-
Apply the paper as it, without embossing it. It looks like
if a transparent paper has been overlayed on the image.
-
Scale
-
Specifies the scale of the texture (in % of the original
file): controls the graininess of the texture.
-
Relief
-
Specifies the amount of embossing to apply (3-150).
-
Brush tab
-
"Brush" is a general term for any material used to paint. A list
of brushes is available with a Preview for
the selected one.
-
Gamma
-
Changes the gamma (luminosity) of the selected brush. The
gamma correction brightens or darkens midtones.
-
Select
-
You can also use a brush pattern you have created by
selecting its image (arrow button on the Select line). This
image must be on your screen before you launch the filter to
be taken in account. Of course, don't use big images.
If your image has several layers, they also will be
displayed in the Select list and can be used as a brush.
When selected, the layer appears in the brush preview and
the normal brush is deselected.
The Save as
button allows you to save the selected brush.
-
Aspect ratio
-
Specifies the brush proportions, height (0 -1) and width (0
+1).
-
Relief
-
Specifies the amount of paint used for each stroke. This may
evoke painting with a palette knife.
-
Orientation tab
-
This tab allows to set the orientation of the brush strokes. A
painter is not obliged to go over with the same paintbrush angle.
To perform some effects, he can vary their orientation.
-
Directions
-
With this option, you can set how many times the brush will
pass through a same place, with each time a different
direction, resulting in a more and more thick paint.
-
Start Angle
-
Specifies the general direction of the strokes, the angle
that the angle range will start from. Directions are often
chosen to give some movement to the image.
-
Angle Span
-
Specifies the angle, the sector, of the stroke "fan".
-
Orientation
-
Specifies the direction of the brush strokes.
-
Value
: Let the Value (luminosity) of the region determine the
direction of the stroke.
-
Radius
: The distance from the center of the image determines
the direction of the stroke.
-
Random
: Select a random direction for each stroke.
-
Radial
: Let the direction from the center determine the
direction of the stroke.
-
Flowing
: Not a direction question here: the strokes follow a
"flowing" pattern.
-
Hue
: Let the hue of the region determine the direction of
the stroke.
-
Adaptive
: The brush direction that matches the original image
the closest is selected.
-
Manual
: The Edit button opens the
Edit orientation Map dialog
that allows you to set the directions manually.
-
Size tab
-
This tab allows you to set the number of brush sizes that will be
used to paint, the limits of variation of these sizes and the
criterion used to determine them.
-
Three Sliders
-
You can specify how many brush sizes are to be used and
their sizes.
-
Sizes: The number of brush sizes to
use.
-
Minimum Size and
Maximum Size : The brush sizes are
between these two values. Greater the size, greater the
length and width of strokes.
-
Sizes
-
You have there options to specify how the size of strokes
will be determined.
-
Value: Let the Value (luminosity)
of the region determine the size of the stroke.
-
Radius : The distance from the
center of the image determines the size of the stroke.
-
Random : Select a random size for
each stroke.
-
Radial : Let the direction from the
center determine the size of the stroke.
-
Flowing : Not a length question
here: the strokes follow a "flowing" pattern.
-
Hue : Let the hue of
the region determine the size of the stroke.
-
Adaptive : The brush size that
matches the original image the closest is selected.
-
Manual : The
Edit button opens the
Size Map
Editor. That allows you to specify the size of
strokes by yourself.
-
Placement tab
-
In this tab you can set how strokes will be distributed.
-
Placement
-
In the preview of the Orientation Map Editor, all small
arrows look like a flow around objects. Inside this flow,
strokes may be placed in two different ways:
-
Stroke Density
-
The greater the density the closer the strokes. With a low
density, the paper or background may be visible in unstroke
areas.
-
Centerize
-
Focus brush strokes around center.
-
Color tab
-
In this tab, you can set what the stroke color will be.
-
Color
-
You can set the stroke color in two ways:
-
Color Noise
-
This slider, and its input box, allow you to introduce noise
in the stroke color, that will look less homogeneous.
-
General tab
-
In this tab you can set what will be the background and the relief
of brush strokes.
-
Background
-
-
Keep Original: The original image
will be used as a background.
-
From Paper: Copy the texture of
the selected paper as a background.
-
Solid: By clicking on the color
dwell you can select a solid colored background.
-
Transparent: Use a transparent
background. Only the painted strokes will be visible.
This option is available only if your image has an
Alpha channel.
-
Paint Edges
-
If it is disabled, a thin border will not be painted around
the outside border of the image.
-
Tileable
-
If checked, the resulting image will be seamlessly tileable.
The right side will match the left side and the top will
match the bottom. This is interesting if your image will be
repeatedly used in a Web background.
-
Drop Shadow
-
Add a shadow effect to each brush stroke.
-
Edge Darken
-
How much to darken the edges of each brush stroke. This
increases paint relief or thickness.
-
Shadow Darken

How much to darken the brush shadow.
-
Shadow Depth
-
How far apart from the object the drop shadow should be.
-
Shadow Blur
-
How much to blur the drop shadow.
-
Deviation Threshold
