You can create a selection based on the color values of pixels here. In the
|
|
dropdown box, choose which color range you want to select. Pixels will be
|
|
selected according to their color value on this scale (⪚ a fully yellow
|
|
pixel would score maximally on the yellow scale and on the red and green scales).
|
|
If you check the <guilabel>Invert</guilabel> box, the selection becomes inverted:
|
|
pixels will become selected if they have a lower value in the specified range instead.
|
|
You can choose whether the current selection should be
|
|
added to or subtracted from the color range selection by clicking the
|
|
respective option: <guilabel>Add to current selection</guilabel> or
|
|
<guilabel>Subtract from current selection</guilabel>. Choose
|
|
<guibutton>Select</guibutton> to actually perform the selection or
|
|
<guibutton>Deselect</guibutton> to remove these pixels from the selection.

This dialog allows you to convert your image from one color space to another.
|
|
The <guilabel>Target color space</guilabel> and <guilabel>Destination ICM
|
|
profile</guilabel> are used to set to which colorspace and profile the image
|
|
will be converted. You can influence how this conversion is done with the
|
|
<guilabel>Rendering Intent</guilabel> option.
|
|
</para>
|
|
<para>
|
|
With <guilabel>Perceptual</guilabel> conversion, the source color space is
|
|
mapped linearly to the destination color space. If the destination color space
|
|
<quote>accepts</quote> a lesser color range than the source, shifts may occur
|
|
because the range is compressed. <guilabel>Relative colorimetric</guilabel>
|
|
conversion converts every color to the closest color in the destination color
|
|
space. This may mean that a certain color range is mapped to one color in the
|
|
destination color space. <guilabel>Saturation</guilabel> means that fully
|
|
saturated colors will remain fully saturated, even if this means that the
|
|
actual color is changed. With <guilabel>Absolute colorimetric</guilabel>
|
|
conversion, the same approach is used as with <guilabel>Relative
|
|
colorimetric</guilabel>, but the white point of the color space (the value
|
|
designating the color white) is not changed to match the new color space,
|
|
which may result in unwanted changes to near colors.

In this dialog you can change a couple of image properties. First of all, the
|
|
<guilabel>Name</guilabel> of the image. If you did not set a name earlier
|
|
(that can also be done when creating the image), it will have a default name
|
|
like <quote>Image1</quote>. Then, you can set its size (determined by the
|
|
<guilabel>Width</guilabel> and <guilabel>Height</guilabel> in pixels and
|
|
the <guilabel>Resolution</guilabel> in dots per inch) and the color profile to
|
|
be used (<guilabel>Profile</guilabel>). Finally, you can fill in the
|
|
<guilabel>Description</guilabel> field with any information you want to add to
|
|
the image.

This dialog lets you resize your image. In the top part, you can choose the
|
|
way the image is resized. If you choose <guilabel>Resize</guilabel>, the size
|
|
of the image is changed, but its layers (which contain the actual contents)
|
|
will not be modified. So, when you double the height and width of the image,
|
|
your original image will occupy the top-left quarter part of your new image.
|
|
On decreasing the size of your image, the image layers will stretch out over
|
|
the image borders, unless you choose <guilabel>Crop layers on image
|
|
resize</guilabel>, which will crop all layers to the new image size.
|
|
</para><para>
|
|
With <guilabel>Scale</guilabel>, the image layers will be resized with the
|
|
image. So increasing the image size will actually enlarge the contents, and
|
|
similar for decreasing.
|
|
</para><para>
|
|
Under <guilabel>Pixel dimensions</guilabel>, you can set which new size you
|
|
want the image to have. The original size is given as a reference. The new
|
|
size can be set both as pixels or as a percentage, with 100% being the
|
|
original size. If you select <guilabel>Constrain proportions</guilabel>, the
|
|
new width and height will always be set to the same percentage. For example,
|
|
if you have an image of 200 x 100 pixels, and set the width to 20 pixels, the
|
|
height will automatically be changed to 10. With this checkbox unselected, you
|
|
can also resize the image non-proportionally.
|
|
</para><para>
|
|
The <guilabel>Filter:</guilabel> dropdown box can be used to select a
|
|
different algorithm for determining the colors of the pixels in the newly
|
|
resized image that did not correspond to a pixel in the old image (the
|
|
calculated corresponding location in the old image was located in between
|
|
pixels). <guilabel>BSpline</guilabel> uses a 4 x 4 pixel grid and results into a quite high
|
|
blurring. <guilabel>Bell</guilabel> is quite fast while resulting in a reasonably smooth image.
|
|
<guilabel>Box</guilabel> is the fastest method, but yields the least appealing result. <guilabel>Hermite</guilabel>
|
|
keeps the image quite sharp, while smoothing it as well, and is reasonably
|
|
fast. <guilabel>Lanczos3</guilabel> results in sharp images, but is very slow. <guilabel>Mitchell</guilabel> (the
|
|
default) is not very fast, but often yields a good intermediate result.
|
|
<guilabel>Triangle/Bilinear</guilabel> uses the 2 x 2 pixel grid around the calculated location
|
|
resulting in relatively sharp lines.

With this dialog, you can rotate the image. The top part of the dialog shows
|
|
the result of the rotation in the form of a change in dimension (if any).
|
|
Under <guilabel>Direction</guilabel> you can choose between
|
|
rotating clockwise and counter-clockwise. Under <guilabel>Angle</guilabel>,
|
|
you can set the amount of rotation. 90, 180 and 270 degrees can be selected
|

using the respective option button, other amounts need to be specified with

the <guilabel>Custom</guilabel> spin box.

With this dialog, you can separate (part of) your image. Every color component
|
|
(channel) will be put into a separate layer or image. At the top of the
|
|
dialog, the current color model is shown. Below that, a couple of options can
|
|
be set.

</para>

<para>

Under <guilabel>Source</guilabel>, you can choose what part of the image to
|
|
separate. The two options are <guilabel>Current layer</guilabel>, which
|
|
(obviously) only uses the currently selected layer and <guilabel>Flatten all
|
|
layers before separation</guilabel>, which uses the entire image.
|
|
</para>
|
|
<para>
|

Under <guilabel>Output</guilabel>, you can choose where the result of the

separation should be written to: either to a couple of layers, or to a couple
|
|
of images.

Under <guilabel>Alpha Options</guilabel>, you can choose what should be done

channel, be discarded, or separated on its own.

The two options at the bottom of the dialog, finally, determine whether the
|
|
source should be downscaled to 8 bit colors (if it contains more), and whether
|
|
the output should be in color (default is to separate the channels to grayscale
|
|
values).

This dialog allows you to shear your image. By shearing, the bounding
|
|
rectangle of your image is transformed into a parallellogram. One pixel
|
|
row/column is kept in place, the next one is shifted by a certain amount, the
|
|
next one by the same amount relative to the previous one, etcetera.
|
|
The X and Y shearing angles can be set using the two spin boxes.

With this dialog, you can add a drop shadow effect to the current layer.
|
|
Select the X and Y offsets (displacements) of the shadow relative to the
|
|
original layer with the two topmost spin boxes. The <guilabel>Blur
|
|
radius</guilabel> spinbox determines the radius in which the shadow will be
|
|
blurred (to achieve a smooth transition at the shadow border). If you want
|
|
a special color for the shadow, you can choose one with the
|
|
<guilabel>Color</guilabel> field. The <guilabel>Opacity</guilabel> slider and
|
|
spinbox can be used to make the shadow more or less transparent. Disable the
|
|
<guilabel>Allow resizing</guilabel> checkbox if you don't want the layer to be
|
|
resized in order to give it a shadow.

height will automatically be changed to 10. With this checkbox unselected, you

In this dialog, you can select the type of adjustment layer to add to the
|
|
image. In the left-hand list, you can see the available adjustment layers,
|
|
each with a preview. When you select one, the <guilabel>Preview</guilabel>
|
|
will change to show a correctly scaled preview of what the result of the
|
|
adjustment layer is going to be.

You can then choose to show either the original image or the preview of the
|
|
adjustment layer with the radio buttons below the preview window. The buttons
|
|
next to these allow you to zoom in, zoom out, and refresh the preview,
|
|
respectively. The <guilabel>Autoupdate</guilabel> checkbox determines if the

generic part, at the right. The generic part contains a preview window, which

you can configure using the controls below it. Choose
|
|
<guilabel>Preview</guilabel> or <guilabel>Original</guilabel> depending on
|
|
whether you want the preview window to show the preview of the filter effect
|
|
or the original image. The four buttons at the bottom right allow you to zoom
|
|
in and zoom out, set the zooming factor to 100% (this shows the image at its
|
|
original size), and refresh the preview, respectively. Furthermore, the option
|
|
<guilabel>Autoupdate</guilabel> determines if the preview window is updated

The curve diagram has a histogram-like background that shows you the abundance
|
|
of various brightness levels. The curve itself (initially a diagonal line from
|
|
bottom left to top right) determines to which new brightness level (on the
|
|
vertical axis) pixels with a certain original level (on the horizontal axis) are
|
|
to be mapped. For example, the default diagonal line from bottom left to top
|
|
right sets every original pixel to its own brightness value, meaning no
|
|
change. A horizontal line means that all pixels will get the same brightness.
|
|
This means minimal contrast, the brightness itself is indicated by the height
|
|
at which the line is placed.

You can click on a handle (red circle) to select it (a selected handle is

|
|
strictly from left to right). If you click on the curve, a handle is added to

|
it at that position. Clicking somewhere else in the image will also add a
|
|
handle at that point. You can press <keycap>Delete</keycap> to delete the

currently selected handle.

You can apply a bumpmap effect and customize it using this dialog. One layer
|
|
is used as bumpmap layer: it is read as grayscale image and the gray values of
|
|
its pixels are used to to distort the other layer for creating the depth
|
|
illusion. High grey values, &ie; more white, mean a larger height, small
|
|
values, &ie; near black, mean a smaller height — or a larger depth, the
|
|
height can get <quote>below sealevel</quote>. A light source, shining
|
|
<quote>from above</quote> on the image that lies <quote>on the ground</quote>,
|
|
is simulated to determine the depth and direction of the shadows.
|
|
</para><para>

The first option in this dialog offers you the selection of the
|
|
<guilabel>Bumpmap layer</guilabel>.
|

</para><para>
|
|
Under <guilabel>Type</guilabel>, you can select what kind of bumpmap to be
|
|
applied. There are three types, <guilabel>Linear</guilabel> (a normal
|
|
application of the bumpmap), <guilabel>Spherical</guilabel> (focusing on the
|
|
extremes, that is, the shadow and highlight values) and
|
|
<guilabel>Sinusoidal</guilabel> (focusing on the midtone values).
|
|
</para><para>
|
|
Then, there are three options to modify the bumpmap apart from its
|
|
algorithmical application. With <guilabel>Compensate for darkening</guilabel>,
|
|
the image is restored to about its original average lightness if using the
|
|
bumpmap filter would make it darker. The <guilabel>Invert bumpmap</guilabel>
|
|
option creates an inverted bumpmap (high and low are reversed). With
|
|
<guilabel>Tile bumpmap</guilabel>, a bumpmap layer that is smaller than the
|
|
layer it is applied to, will be tiled (repeatedly) to cover the entire layer.
|
|
</para><para>
|

Under <guilabel>Settings</guilabel>, you can select the mathematical

|
parameters for the bumpmap. First of all, <guilabel>Azimuth</guilabel> (the
|
|
angle of the light source in the X-Y plane), <guilabel>Elevation</guilabel>
|
|
(the height of the simulated light source above the surface in degrees, with 0
|
|
degrees being on the ground and 90 degrees being vertically above the image),
|
|
and <guilabel>Depth</guilabel> (the maximal vertical distortion of the image).
|
|
</para><para>
|
|
Then, there are the <guilabel>X offset</guilabel> and <guilabel>Y
|
|
offset</guilabel>, with which you can displace the bumpmap layer relative to
|
|
the destination layer, <guilabel>Water level</guilabel> (the depth seen as
|
|
neutral), and <guilabel>Ambient light</guilabel>, which determines the
|
|
relative amount of ambient (environmental) light.

With this filter, you can apply a customized distortion effect to your image.
|
|
The nine spinboxes at the top left determine the distortion. Each pixel is
|
|
assigned a new value based on these values: the old color values of the pixel
|
|
inself and the eight surrounding pixels are each multiplied by the values in
|
|
the respective spinboxes, these results are added, and the final result is the
|
|
new color value for the pixel. Before being applied, this final result can be

multiplied with a certain <guilabel>Factor:</guilabel> or a certain
|
|
<guilabel>Offset:</guilabel> can be added to it.

own (the 1 in the center), to which are added the values of the pixels to its

value, since multiplying by one has no effect), and from which are subtracted

the values of the pixels to its bottom right and directly above it (added with

This dialog allows you to customize a Gaussian noise reduction. The
|
|
<guilabel>Threshold</guilabel> setting is a measure for how much noise should
|
|
be removed (&ie; how quickly a <quote>lonely</quote> pixel should be made
|
|
equal to its surroundings), while the <guilabel>Window Size</guilabel> setting
|
|
determines the radius of the area considered when changing pixels.

With this dialog, you can fix an image which is distorted due to common lens
|
|
anomalies. You can specify a <guilabel>Distortion correction</guilabel>,
|
|
indicating how much the image should be corrected if its
|
|
concaveness / convexness is not right, for areas near the center and areas
|
|
near the edges. If you want an asymmetrical correction, you can specify
|
|
different <guilabel>X</guilabel> and <guilabel>Y</guilabel> coordinates for
|
|
the center (in percentages of the total width and height, measured from the

top left).
