# verify-win16-icon.sh - a Win16 program's icon as Windows 3.1 shows it.
|
|
#
|
|
# make binds every Win16 program's icon into its executable (make/win16.mk:
|
|
# tools/iconBake ico16, 32x32 in the 16 VGA colours, resource
|
|
# HOSTED_ICON_ID), and the backend gives its window class that icon. Here
|
|
# Program Manager is Windows' shell and WIN.INI's load= starts DRAW
|
|
# (examples/draw) minimised, so Windows draws the class's icon on the
|
|
# desktop -- and DRAW runs on, minimised, presenting to a window with no
|
|
# room. DOSBox's own screenshot of the 800x600 screen must hold the baked
|
|
# icon: every pixel of it the icon's mask leaves opaque, in its colour.
|
|
#
|
|
# Usage: scripts/verify-win16-icon.sh
|
|
# Env: WIN16_ICON_KEEP keep the screenshot as build/win16/win16-icon.png
|
|
# Exit: 0 PASS, 1 FAIL, 2 SKIP (Windows or DOSBox not installed, or DRAW
|
|
# not built)
|
|
# Requires: DOSBox Staging, Xvfb, xdotool, the win311
|
|
# component; DRAW.EXE and its icon (make win16).
