Initialization parameters used by Balsac for basic graphics settings can be modified inside the basic color window, see ibid, and the shading window, see ibid. In addition, the present initialization window allows changing the graphics window size and position.
L-clicking the “Settings | Initialization | Basic parameters ...” entry opens the initialization window.
The top section shows the present values (in pixels) of the origin (x, y) (upper left corner) of the graphics window next to “Xorig =”, “Yorig =”. Further, the present window size, width ww and height hh, is shown next to “Width =”, “Height =” (both values in pixels). The values of the four window parameters can be modified where changes (by typing inside the corresponding box) are accepted after L-clicking the “Apply” button. This closes the initialization and the graphics window, opens a new graphics window with the updated position /size definitions, and redraws the particle inside.
Note that a more direct way of moving and resizing the graphics window of Balsac is by mouse dragging analogous to standard MS windows procedures.
The middle section to the left allows to modify basic color and shading parameters used in the graphics window where
L-clicking the “Basic colors” button opens the basic color window allowing to change all details of the color palette as described elsewhere.
L-clicking the “Light/shading” button opens the shading parameter window allowing to change all details connected with shading atom balls as described elsewhere. Note that this option is available only if
Note that the shading option is available only if hard, fuzzy, glossy shaded, or brilliant balls are used to show atoms of a particle.
The middle section to the right allows to choose between help engines used to view the Balsac help file where the radio buttons next to "Html" and "Windows XP" show the present setting by a black dot inside the corresponding button. L-clicking at button
"Html" applies the most recent html based help engine together with help file Balsac4.chm. This is the default help option for Windows 7 and later.
"Windows XP" applies the old help engine (WinHlp32.exe) together with help file LEEDpat4.hlp. This option is meaningful only for Windows XP and earlier or if the old help engine (WinHlp32.exe) is installed. WinHlp32.exe can be downloaded from Microsoft at http://support.microsoft.com/kb/917607 and installed free of charge.
The bottom section collects function buttons where
L-clicking the “Default” button resets the definition of the graphics window to default values (origin at (0, 0), ww = 600, hh = 450 in pixel units), closes the initialization and the graphics window, opens a new graphics window with the updated position /size definitions (if changed), and redraws the particle inside.
L-clicking the “Close” button closes the initialization window ignoring any changes made in the input boxes and redraws the particle inside the graphics window.
L-clicking the “Apply” button closes the initialization and the graphics window, opens a new graphics window with the updated position /size definitions (if changed), and redraws the particle inside.
