Documentation - Painting And Tools

Again, the main interface for Pocket Artist is shown to the right.

The Pocket Artist tool popup menus are as follows:

Each persistent tool has its own status/options bar that appears in the second bar when you select that tool.

Pocket Artist features "smart sliders" -- that is, to save space, the function of a slider track bar is not given right away. By dragging the nub back and forth, the value of the slider is shown, along with a description of what the slider is affecting.

Below, brief descriptions of each tool and explanations of their status/options bars.
Drawing Tools

Paintbrush: this is the standard paintbrush. By clicking and dragging in the document window, you paint with the foreground color using the current brush. You can also hold down Shift (HPC) or Action (PPC) and click and it will draw a line from the last point of which you drew. The Sketch checkbox puts the brush in Sketch mode, which is a different way of drawing. As you draw In Sketch Mode, your brush strokes are cascaded onto those you have already made. In other words, the brush effect gets darker and darker as you go over the same area. In the example to the right, the top stroke is Paintbrush at 20% opacity in normal mode. As you sketch over the same area, it doesn't get any darker than 20%. In Sketch Mode (the second stroke), it gets darker and darker, giving the appearance of a pencil sketch or something similiar. In the third example, the Blending Mode has been set to "Multiply" (which in effect darkens the image), and the Sketch Mode keeps darkening as one goes over the same area. The bottom row of strokes are examples of varying opacity in Normal Mode (the first five strokes) and Sketch Mode (the last six strokes). The "Normal" box chooses the blending mode for the Paintbrush. Blending modes are described below. The slider affects opacity of the brush.

Pencil: The pencil is much like the Paintbrush except that it puts the current brush in a "Clamped Mode" -- that is, where it would normally have soft edges, Pencil makes these hard edges. For example, the edges of the diamond brushes are light and soft (and drawn that way with the paintbrush) but with the pencil they are hard and drawn on/off on a pixel-by-pixel basis. Options are identical to Paintbrush.

Eraser: Eraser is identical to the pencil, except that it draws with the background color and there is no Sketch Mode. In a future release that supports layers, the functionality of eraser will be enhanced.

Dodge/Burn: The dodge/burn tool lightens or darkens parts of an image. The options enable the user to affect shadows, midtones, or highlights, as well as the pressure of the dodge (lighten) or burn (darken). See the example to the right. The first column of strokes is Dodge, the second is Burn. The top row is affecting Highlights, the second is affecting Midtones, and the third is affecting Shadows. Note how the Highlight Dodge affected the pink flower much more than the Midtone Dodge, and how the Shadow Dodge affected the dark area much more than the Highlight Dodge.

Smudge: the smudge tool is like taking a wet finger to your painting. It has the Blending Mode and opacity option of the Paintbrush tool. The 'Wet' option is where the smudge changes take effect upon themselves. Put more plainly, without the smudge being wet, there's little it can truly do to an image. When wet, smudge almost acts as a watercolor finger painting. It's recommended that the opacity is turned down to 90% or so when wet, as to allow the original image to "bleed back through" as one is painting.

Eyedropper: the eyedropper tool looks at the image and grabs the color at that point and uses it as the foreground color. There are several options to how the color is retrieved from the image. A 3x3 or 5x5 surrounding box can be used to fetch the image (if the point is in a 'noisy' group of samples) and there are "averaged" and "weighted" modes, where in weighted mode, points near the center of the box sample are given more weight to the average.

Paintbucket: fills an area with the current foreground color. The area that it fills is determined by the picture itself. You pick a tolerance value of 0 to 255 ("Tol." in the options bar), and then by clicking in the image, a flood fill will take place across all pixels whose colors are within the tolerance value of the original pixel you clicked on. Clicking "AA" enabled antialiasing of this flood fill. Blending mode and opacity are additional settings to control the fill.

Blur/Sharpen: blurs and sharpens bits of the image interactively. Select the "pressure" (amount) of the tool and draw on the image to blur or sharpen individual parts of it.

Rubber Stamp: takes one area of your image and paints it into another area. By holding down Action (PPC) or Shift (HPC) and tapping, you set the "source point." Then, let go of the key and all strokes after that act as a stamp coming from the source point. In the example to the right, the source was set on the cusp of the petal to the left of the main flower. When "Aligned" is unchecked, you get behavior as of that in the bottom left of the example. Each tap acts as if the source is put right there in the image at that position. By enabling "Aligned," each tap results like that of the example near the right, where the relative position of the source of the stamp is saved between taps/drags. Blending mode and opacity values are also able to be set.

Texture Brush:paints with an external picture as its "source." Click the "Tex" button to bring up the Texture choice window (shown at right). A listing of images found in the "Textures\" subdirectory off of the Pocket Artist install directory will be shown here. By choosing an image, it will be shown in the window. Clicking OK will bring you back to your document. Painting in the document will now use the texture (and tile it appropriately) instead of the current foreground color along with the current brush shape. By enabling the "use as bump map" with the texture brush, the tool takes on a completely different feel. Now, the current foreground color and brush are used, but the texture acts as a "rough surface" that you are painting on -- for example selecting the canvas texture makes it appear as though you are painting on canvas.
Due to the way it functions, for best results enable the Sketch mode for this tool (the "S" checkbox), and set the opacity to a low value (around 20% to 40%). It will appear as though you are drawing with pencil or charcoal on rough paper. Different textures yield different results, and some nice effects can be made. Blending mode, sketch mode, and opacity can be set with this tool.


Draw Text/Text Outline: These tools enter text into Pocket Artist. Draw Text will make a new floating selection on your document with the text entered in the current foreground color, while Text Outline will simply make a selection based on the text you enter. Options include font name, size, bold, italic, and whether the font should be antialiased. There is an experimental "angle" feature where the text can appear at an angle. By simply tapping (when the Text tool is selected) in the document the "Enter Text" dialog will pop up and prompt for the text -- tapping OK will float the text (or outline) on the document. By tapping and dragging a rectangle on the document, the same thing will happen, except it bypasses Pocket Artist's auto-calulate of the text rectangle. This is useful if you would like to chop off the text, or when working with text at an angle (Pocket Artist does not compute the needed rectangle appropriately).
To the right is a sample of what you can do with the Text tool. The first line is simply "Pocket Artist" in bold italic Tahoma. The second line is the same, except with anti-aliasing turned on. The third was two instances of the text tool. The first was set to gray and blurred after placement, and then black text on top, creating a drop shadow effect. The last example shows that the floating text that is placed after using the text tool is just like any other floating selection, and has opacity and blending mode settings.

Rectangle: this is a quick shapes tool. By tapping and dragging, you create a rectangle on the document. Hold down Shift (HPC) or Action (PPC) to make the rectangle a square. The options are opacity and blending mode, as well as whether to fill the rectangle or have it use an outline instead. Check the box next to "1px" to make the rectangle draw as an outline. The thickness of the rectangle outline can be set as well.

Ellipse: this draws an ellipse, much like in the way the rectangles are drawn. Hold shift or Action to make a circle. It can be forced to draw as an outline as well. The "AA" checkbox specifies if the shape/outline is to be drawn antialiased (smooth).

Polygon: this draws a polygon. By repeatedely tapping where the points of the polygon should go, then by tapping at or very near the first point, a polygon will be drawn. The options are much like the ellipse tool: blending mode, opacity, and whether it should be an outline. Also the polygon may be drawn smoothly.

Draw Line: this draws a line. By tapping and dragging you set the start and end points of the line. Options include the thickness of the line, blending mode, opacity, and whether to make it smooth or not.

An example of the different shapes and their settings is shown to the right.
