Image Labels - aaronwmorris/indi-allsky GitHub Wiki
Overview
The image label can now be customized using a template and python string format codes.
Information regarding python string formats may be found here: https://docs.python.org/3/library/string.html#formatspec

Note: Leave enough room for additional labels after your last entry. indi-allsky will add additional labels such as moon mode and eclipse info at the end. It is best to return to the upper left or right so that space is available.
Label Colors
The color of the text may be changed by adding a formatted comment color:#,#,# The numbers are RGB color codes. The color is persistent for all subsequent lines and can be changed as many times as you wish.
# default color is used if none specified
{timestamp:%Y.%m.%d %H:%M:%S}
# color:255,0,0 additional text is ignored
Lat {latitude:0.1f} Long {longitude:0.1f}
# comment does nothing
# color:0,255,0
Exposure {exposure:0.6f}
Label Location
The location of the text can be changed using xy:#,# The numbers are X,Y coordinates. The coordinates are persistent for all subsequent lines and can be changed as many times as you wish.
A negative X coordinate will offset from the right side of the image.
A negative Y coordinate will offset from the bottom of the image.
# xy:100,200 color:0,255,0 coordinates may be combined with color
{timestamp:%Y.%m.%d %H:%M:%S}
Lat {latitude:0.1f} Long {longitude:0.1f}
Exposure {exposure:0.6f}
Text justification (Pillow-only)
If you want to right (or center) justify your text, you can add an anchor configuration for Pillow. A ra anchor combined with negative offsets will draw the text offset from the right/bottom of the image.
The default anchor is la for left-ascender.
{timestamp:%Y.%m.%d %H:%M:%S}
# xy:-30,30 anchor:ra right-ascender This will draw text offset from the right top of the image.
Lat {latitude:0.1f} Long {longitude:0.1f}
# xy:30,60 anchor:la left-ascender Return to original location
Exposure {exposure:0.6f}

Text size (Pillow-only)
{timestamp:%Y.%m.%d %H:%M:%S}
# size:40
Lat {latitude:0.1f} Long {longitude:0.1f}
# size:30
Exposure {exposure:0.6f}
OpenCV vs Pillow
OpenCV only supports ASCII characters and limited internal fonts. Pillow is much more capable with TrueType font support.
