INSTRUCTIONS
NOTE: One version of FreeType is referred as "base" version and the
other as the "test" version.
1. Get the two versions ready
-------------------------------------
Download an older version of FreeType (For example : 2.6.5)
( This being the "base" version of the two)
Go to 'include/freetype/ftoption.h' and uncomment this line
#define FT_CONFIG_OPTION_SUBPIXEL_RENDERING
2. Compile the two versions
-------------------------------------
Go to the "base" version's folder and compile the library.
./configure --enable-shared --disable-static
make
Repeat step 2. for the "test" version as well.
3. Compile the code
-------------------------------------
Return to this folder and make the binary
make tests
4. Run the executable
-------------------------------------
=> Set resolution in DPI by passing argument to variable FT_TEST_DPI.
=> Set the Rendering mode by passing FT_TEST_RENDER_MODE.
FT_TEST_RENDER_MODE can take values 1. MONO
2. AA
3. RGB
4. BGR
5. VRGB
6. VBGR
=> Set the variables FT_TEST_BASE_DLL and FT_TEST_TEST_DLL to
point to the libfreetype.so file of the base and the test
versions respectively.
By default, the folders '$(HOME)/base/' and '$(HOME)/test/'
folders are set for FT_TEST_BASE_DIR and FT_TEST_TEST_DIR
respectively. If FT_TEST_XXX_DLL isn't defined, these values
are taken to search for DLL files.
=> Set FT_TEST_FONT_FILE to the path to font files needed.
=> set FT_TEST_PT_SIZE as a number to denote the font size.
EXAMPLE: FT_TEST_BASE_DIR=/home/wl/kushal/base \
FT_TEST_TEST_DIR=/home/wl/kushal/test \
FT_TEST_DPI="72 96" \
FT_TEST_FONT_FILE="test.ttf" \
FT_TEST_RENDER_MODE="AA RGB" \
FT_TEST_PT_SIZE="16 20" \
./runme.sh
( The values in the above example denote the default values
for the variables )
Open ./html/top.html for the web interface.
