2.4 Color

The color chooser provides several tools for selecting fill and outline colors. The selected color is applied to selected geometry as outline or fill color, depending on which toggle button under Apply Color To is active.

Figure 1.17: Apply color to outline or fill
The presently selected fill and outline colors are also applied to all newly constructed geometry. A graphical representation of the color scheme is displayed under Current Color. This current scheme can be applied to selected geometry without the need to re-select colors from the color chooser by using the button labeled Apply Color Scheme to Selected.

Figure 1.18: Current Color Scheme
The first set of 16 colors ( Basic Colors) corresponds to the IconSmith's polygon outline colors. When building icons for the IRIX platform, only these colors should be used for polygon outlines in order to maintain compatibility.

Figure 1.19: Basic Colors, IconSmith's Outline Colors
The next set of 136 colors ( More Colors) corresponds to the similarly laid-out color chooser in IconSmith. For icons that do not need to conform strictly to the original FTI specifications, these colors can be used for outline and fill for all geometry.

Figure 1.20: More Outline and Fill Colors
A set of four Named Colors ("None", "Outline", "Icon", and "Shadow") is available, where "None" refers to transparency. For example, a polygon without a fill color should be assigned "None" for fill color.

Figure 1.21: Named Colors
Finally, a standard color chooser provides the possibility of selecting any one of a 24-bit (16+ million) color scheme. The button for "Color Chooser" opens a separate dialog with three variants of color choosers. The selected color from this dialog is placed into the color sample button. As more custom colors are selected from the color chooser, previously used colors are moved to the smaller sample boxes, from where they can be selected for repeated use.

Figure 1.22: Extended (full RGB) Outline and Fill Colors
This custom color chooser is non-standard to FTI icons and has been added for the convenience of generating icons with a much larger color palette. To this end, the FTI code has been modified to accept colors in RGB format. These FTI commands will not load in the original IRIX desktop!

A separate Pick Color tool is available to set the current color scheme to a specific geometry's color.

2.5 Grid

The grid is represented by light gray points in the drawing area. It corresponds to the grid in IconSmith, and is designed to aid in designing orthographic three-dimensional objects.

Figure 1.24: Grid
This grid can be made visible/invisible from the menu option " Edit -> Grid". Regardless of its visibility, the Grid Snap tool can be enabled to magnet/snap the mouse cursor to the grid points. This is particularly useful when designing three-dimensional objects that conform to the suggested orthographic projection. When the mouse cursor is near or on a grid point and Grid Snap is enabled, it changes its appearance to a red target symbol.

2.6 Template

A GIF or JPEG template image can be imported to help in the construction of new icons. The image can be of any reasonable size, but should conform to a square, otherwise it will appear at a skewed aspect ratio.

The template can be set via the menu option " Edit -> Load Template Image". The image is scaled to accurately fit the drawing area. Menu option "Edit -> Clear Template Image" removes the image from the drawing area.

By default, the template is drawn at 50% transparency. The transparency value can be set via the Template Transparency slider.

2.7 File Operations

FTI icons can be opened interactively from within FTI Editor, or passed as filenames to the command line. The implementation of FTI icons used here accepts the subset of FTI functions in table 1.1, column "Read".

A separate Import menu option is provided to combine geometry from several icons.

Save (As) stores the geometry in an existing or new FTI icon file. The implementation of FTI icons used here writes only functions listed in table 1.1, column "Write".
