Option | Description |
The message |
The message. Note that for many FONTs, upper case will be used instead
of lower case. Also, odd characters (such as [}*%) may be displayed using
a simpler font. Lastly, the $ character has a special meaning: with
$T, $D, and $B signfying the time, date, or a filled box. |
FONT |
The message is written with this font |
Background |
A background image to use |
Color slide |
A foreground image to use. Colors in this image are used instead of the
colors that the FONTS are drawn with. |
Width and scale factors |
Transform the height and width of each character in the message, on a
character by character basis (thus, some characters will be taller and wider
then others). |
Width and Height |
You can specify the width and height of the entire image.
If empty (or set to 0), GIF_TEXT will determine the width and/or height
(as a function of the length of the
message, the FONT selected, and the character specific
width & height scaling). If not
empty, GIF_TEXT will rescale the image to fit into this height and/or
width (note that this rescaling occurs after character specific
scaling). |
Vertical alignment |
Align each character at the top, the bottom, or the middle of the image |
Color slide horizontal fit |
When the color slide is not the same width as the image, you can
stretch the slide to fit, or you can repeat the slide. |
Color slide vertical fit |
Similar to horizontal fit, but only used when the color slide is
more then one row high. Note that using a same slide for all rows
option will convert (for this image only) a multi-row color slide into a
single row color slide. |
Color slide measured from |
Use this to create a color wash starting from anywhere in the image; with
0 0 defined as the top left corner, and 1 1 as the bottom right. The distance
from this point to a pixel in the message image is used to determine
which color slide pixel to use. In contrast, leaving this empty will cause
a columnwise match to be used (after stretching/tiling). |
Color slide threshold |
Use this to determine
how to decide which message image pixels to convert to
color slide colors. You can use the pixel number, or the maximum or
the average brightness (of the RBG colors). You can also have this threshold
vary over the image. |
Color slide probability |
A fade-into effect: determines the probability of using a color slide
color (given the threshold has been met). High probabilities (near 1.0) mean
use the color slide color, low probabilities (near 0.0) mean to use
the alphabyte's color. |
Number of colors in user defined color slide |
Instead of using a color slide file (a .GIF file), you can
specify your own. The size (which should be less then 255) determines
the length & number of colors in this color slide |
Red, Green, Blue intensity parameters |
Each of these should be a space delimited list of values between
0 and 1. Each of these are used to create graphs (with segment
endpoint defined at each of these values).
The user defined color slide is determined by the looking up (an R,B, and B
value) on these graphs.
|
Background and Text colors |
The background and text (foreground) color. Used when background
images and color slides are not used. |
Transparent color index |
Used to allow background to show through -- a value of 0 (the default)
is almost always used. |
Scale background |
Stretch or tile the background image (to the size determined by
height & width). |
Time and Date format |
Select one of several time and date formats. Note that the
time is written when a $T is included in the message, and the date
when $D is included. |
