From d0091a33fcdb49b65a6f20f775cfde520380b1fa Mon Sep 17 00:00:00 2001 From: =?utf8?q?S=C3=B8ren=20Sandmann=20Pedersen?= Date: Wed, 21 Dec 2011 05:19:00 -0500 Subject: [PATCH] Modify gradient-test to show a bug in NONE processing This patch modifies demos/gradient-test to display a bug in gradients with a repeat mode of NONE. With the current gradient code, the left side will be a solid red (actually an extremely long fade from solid red to transparent) instead of a sharp transition from red to green. --- demos/gradient-test.c | 13 ++++++------- 1 file changed, 6 insertions(+), 7 deletions(-) diff --git a/demos/gradient-test.c b/demos/gradient-test.c index 20f78a6..e68f69a 100644 --- a/demos/gradient-test.c +++ b/demos/gradient-test.c @@ -15,12 +15,11 @@ main (int argc, char **argv) int i; pixman_gradient_stop_t stops[2] = { - { pixman_int_to_fixed (0), { 0xffff, 0xeeee, 0xeeee, 0xeeee } }, - { pixman_int_to_fixed (1), { 0xffff, 0x1111, 0x1111, 0x1111 } } + { pixman_int_to_fixed (0), { 0x0000, 0x0000, 0xffff, 0xffff } }, + { pixman_int_to_fixed (1), { 0xffff, 0x1111, 0x1111, 0xffff } } }; - pixman_point_fixed_t p1 = { pixman_double_to_fixed (0), 0 }; - pixman_point_fixed_t p2 = { pixman_double_to_fixed (WIDTH / 8.), - pixman_int_to_fixed (0) }; + pixman_point_fixed_t p1 = { pixman_double_to_fixed (50), 0 }; + pixman_point_fixed_t p2 = { pixman_double_to_fixed (200), 0 }; #if 0 pixman_transform_t trans = { { { pixman_double_to_fixed (2), pixman_double_to_fixed (0.5), pixman_double_to_fixed (-100), }, @@ -44,7 +43,7 @@ main (int argc, char **argv) #endif for (i = 0; i < WIDTH * HEIGHT; ++i) - dest[i] = 0x4f00004f; /* pale blue */ + dest[i] = 0xff00ff00; dest_img = pixman_image_create_bits (PIXMAN_a8r8g8b8, WIDTH, HEIGHT, @@ -74,7 +73,7 @@ main (int argc, char **argv) stops, 2); pixman_image_set_transform (src_img, &trans); - pixman_image_set_repeat (src_img, PIXMAN_REPEAT_PAD); + pixman_image_set_repeat (src_img, PIXMAN_REPEAT_NONE); pixman_image_composite (PIXMAN_OP_OVER, src_img, NULL, dest_img, 0, 0, 0, 0, 0, 0, 10 * WIDTH, HEIGHT); -- 2.7.4
