A parameter that is used to determine the bounding box
created with text
The drawing context installed in this parameter need not be the same
as the ultimate drawing context, but it must measure text in the same
way. In particular, use a post-script-dc% for preparing
PostScript output, while a bitmap-dc% instance will work fine
for either bitmap-dc% or canvas% output.
Draws pict to dc, with its top-left corner at offset
Generates a pict-drawer procedure for multiple renderings of
. Using the generated procedure can be faster than
repeated calls to draw-pict
Opens a frame that displays pict. The frame adds one method,
set-pict, which takes a pict to display. The optional
w and h arguments specify a minimum size for the
frame’s drawing area.
A parameter used to refine text measurements to better match an
expected scaling of the image. The scale/improve-new-text
form sets this parameter while also scaling the resulting pict.
