The texture is drawn using rectangles, polygons and vbos. There is also code to test a rectangle using an atlased texture (which should test the manual repeating) however the validation for this is currently disabled because it doesn't work. http://bugzilla.openedhand.com/show_bug.cgi?id=2063 --- diff --git a/tests/conform/Makefile.am b/tests/conform/Makefile.am index cf595e4..84878d1 100644 --- a/tests/conform/Makefile.am +++ b/tests/conform/Makefile.am @@ -27,6 +27,7 @@ test_conformance_SOURCES = \ test-cogl-multitexture.c \ test-cogl-texture-mipmaps.c \ test-cogl-texture-rectangle.c \ + test-cogl-wrap-modes.c \ test-cogl-pixel-buffer.c \ test-cogl-path.c \ test-path.c \ diff --git a/tests/conform/test-cogl-wrap-modes.c b/tests/conform/test-cogl-wrap-modes.c new file mode 100644 index 0000000..53e6103 --- /dev/null +++ b/tests/conform/test-cogl-wrap-modes.c @@ -0,0 +1,332 @@ +#include +#include + +#include "test-conform-common.h" + +#define TEX_SIZE 4 + +static const ClutterColor stage_color = { 0x80, 0x80, 0x80, 0xff };
