Paint tool + Texture (raster)

Patterns/Textures on the GIMP

Which the differences and likeness between pattern and a brush (.gbr and .gih) on GIMP?

1. Both are the resources to mark or make stains
2. Both are based in raster images
3. Pattern is used to emulate textures in different kind of techniques or
4. To fill figures with textures
5. Brush is used to emulate random textures, of natural properties or not of brushes in the real world.

Well, we can to think the patterns as brush very specific.

How works on Krita

IN PROGRESS

Photoshop - Bob Chiu Steps Video link

• • Create a Pattern > save it on pattern library
  • Create a brush
    • New document (size x height), for instance with 256x256px;
    • New preset brush - on photoshop the brushes birth directly as a preset, interesting (Krita also).
  • Select the brush
  • Now Brush Options > [1]
    • The options is possible to control many aspects:
      • Spacing, Hardness Angle, Flip and Size;
      • Enable the Shape Dynamics (basically is a .gbr with gimp paint dynamics); > [2]
      • Enable the Texture and is possible to see the library patterns, the options of Texture are: > [3]
        • Texture Library (dropdown open manager), Invert (flag), Scale, Brightness, Contrast, Texture each tip (flag), Mode, Depth, Minimum Depth, Deep Jitter, Control (drop down flags).
      • Enable Transfer > [4]
        • Opacity Jitter or Flow Jitter

Proposal of the feature on GIMP

The tool more near of an ideal Brush with Texture features (similar to Krita or Photoshop) is the Clone Tool. Perhaps this Tool is a good way to build a new Tool.

The Brush + Pattern is basically a dual brush where the pattern is a kind of mask in background. Options need are:

1. Colour: Is necessary to use the colour asset on... as a normal brush.
2. Texture aspect: Is necessary to have a flag to choose between default and inverted.
3. Source: Image and Pattern (texture). Image as source is interesting to control something very similar to impasto or smudge.
4. Alignment: Registered and Fixed.

Paintbrush and Pencil with smudge ability (raster)

Basically, this feature is to have the current Smudge tool + a Paint tool (2) together, in an unique tool. Now, the Smudge tool has only the capability to blend the stains, using a brush. The stains that are previously created.

On GIMP, now, is possible to make this in two steps - first we paint something (Pencil, Paintbrush, Airbrush, etc.) and after, with Smudge tool, we make the blend the stains/strokes.

With MyPaint brushes, is possible to have the smudge on their brushes, but the mark is a basically a circle (dab). In the ideal painting world, is interesting to have the raster brushes with dynamic stains. The .gbr and .gih brushes with paint dynamics)... have the result more richest that a smudge brush on MyPaint. Figure smudge brush with MyPaint Figure smudge brush with GIMP (via 2 steps: make stains with some paint tool and after with smudge tool blend them).

Notes
2. Is necessary to link the smudge with all paint tools... or in only specific tool, for instance, the paintbrush?

Brainstorming ---

1. Convolution Matrix in real time > impasto?!

Paint tools and Clipboard feature

All paint tools have the possibility to use the clipboard.

Brainstorming

I am working around an impasto method on GIMP. So, this method use the clipboard feature to brushes and patterns (texture). In my opinion, this feature is a bit forgotten and underused. The feature would had used better in many areas, I think! Then, I am thinking to request an improvement: the capability to select an area on the canvas... via shortcut... directly on canvas with the paint tool current. For example: a) I am using the paintbrush; b) without to change the current tool... I select on-the-fly (via shortcut) an area of my canvas, c) when the area was selected, and shortcut released, the clipboard is loaded the stain.
