From 0629afcaa558d1abfc556460e91c3ab2f21c9f47 Mon Sep 17 00:00:00 2001 From: Pierre Schweitzer Date: Fri, 26 May 2017 08:31:10 +0000 Subject: [PATCH] [GDIPLUS] Import Wine commit (by Vincent Povirk): - b8a8e1bde9382897927945ec0b58b8a2fcfcfe59, Check SHADEBLENDCAPS only for printer devices. In short, this avoids black boxes in GOG setup. This may help other software having rendering issues due to alpha layer. svn path=/trunk/; revision=74665 --- reactos/dll/win32/gdiplus/graphics.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/reactos/dll/win32/gdiplus/graphics.c b/reactos/dll/win32/gdiplus/graphics.c index 158e2b48efe..29ac5d3baf7 100644 --- a/reactos/dll/win32/gdiplus/graphics.c +++ b/reactos/dll/win32/gdiplus/graphics.c @@ -320,7 +320,8 @@ static void transform_and_round_points(GpGraphics *graphics, POINT *pti, static void gdi_alpha_blend(GpGraphics *graphics, INT dst_x, INT dst_y, INT dst_width, INT dst_height, HDC hdc, INT src_x, INT src_y, INT src_width, INT src_height) { - if (GetDeviceCaps(graphics->hdc, SHADEBLENDCAPS) == SB_NONE) + if (GetDeviceCaps(graphics->hdc, TECHNOLOGY) == DT_RASPRINTER && + GetDeviceCaps(graphics->hdc, SHADEBLENDCAPS) == SB_NONE) { TRACE("alpha blending not supported by device, fallback to StretchBlt\n"); @@ -400,7 +401,8 @@ static GpStatus alpha_blend_hdc_pixels(GpGraphics *graphics, INT dst_x, INT dst_ hbitmap = CreateDIBSection(hdc, (BITMAPINFO*)&bih, DIB_RGB_COLORS, (void**)&temp_bits, NULL, 0); - if (GetDeviceCaps(graphics->hdc, SHADEBLENDCAPS) == SB_NONE || + if ((GetDeviceCaps(graphics->hdc, TECHNOLOGY) == DT_RASPRINTER && + GetDeviceCaps(graphics->hdc, SHADEBLENDCAPS) == SB_NONE) || fmt & PixelFormatPAlpha) memcpy(temp_bits, src, src_width * src_height * 4); else -- 2.17.1
