From b23f732075fc4e1cd9cbf5eaaaaa8ef8dc2b7922 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Sun, 28 Nov 2010 16:06:23 +0800 Subject: [PATCH] st/vega: Use the renderer for vgMask. vgMask renders to the alpha mask with special fragment shaders. The operation can be supported by switching the renderer to FILTER state. --- src/gallium/state_trackers/vega/mask.c | 233 +++++-------------------- 1 file changed, 44 insertions(+), 189 deletions(-) diff --git a/src/gallium/state_trackers/vega/mask.c b/src/gallium/state_trackers/vega/mask.c index ec3e3447d16..3bd9a1e5989 100644 --- a/src/gallium/state_trackers/vega/mask.c +++ b/src/gallium/state_trackers/vega/mask.c @@ -193,49 +193,12 @@ void save_alpha_to_file(const char *filename) } #endif -static void setup_mask_framebuffer(struct pipe_surface *surf, - VGint surf_width, VGint surf_height) +/* setup mask shader */ +static void *setup_mask_operation(VGMaskOperation operation) { struct vg_context *ctx = vg_current_context();
