# In this directory, a number of different processes are managed:
#
# 1) PNG files are created from SVG files for each icon theme and needed bitmap resolution
# 2) An images.tar.gz file is created from all the PNG files

# Step 2) is universal and is done for any builder, whereas step 1) is
# optional and depend on MAINTAIN_PNGS being defined in CMake.  The reason we
# can skip 1) is that the *.PNG files are part of the source tree so
# do not need to rebuilt by a typical builder.  However, because the *.PNG files
# are part of the source tree, and subject to version control, they should be built
# only when needed, otherwise this results in a diff for the version control system.
# Therefore step 1) is driven by CMake (if MAINTAIN_PNGS) which gives
# us conditional *.PNG building based on an edit to the respective *.SVG file.

# If MAINTAIN_PNGS is not defined, then you are a normal builder and no special
# tools are required.  If MAINTAIN_PNGS is defined, then you are a PNG maintainer
# and will need the following tools findable in your PATH:
#
# 1) inkscape - command line mode is used, must be on your PATH
# 2) pngcrush - this program must be on your PATH
#

# lower case is used for local variables, uppercase for global variables

option( MAINTAIN_PNGS
        "Set to true if you are a PNG maintainer and have the required tools given in the resources/bitmaps_png/CMakeLists.txt file (default OFF)."
        OFF)

# SMALL - for menus         - 16 x 16
# MID   - for toolbars      - 24 x 24
# BIG   - for program icons - 48 x 48
# which are given on three basename lists: BMAPS_SMALL, BMAPS_MID,and BMAPS_BIG
# respectively.  The basename is without file extension and without path.
# A corresponding ${basename}.svg file must exist in 'sources' dir below here.
