From: dooglus Date: Wed, 26 Nov 2008 18:33:15 +0000 (+0000) Subject: Rename the Random class in the mod_noise module to RandomNoise to stop it clashing... X-Git-Url: https://git.pterodactylus.net/?a=commitdiff_plain;h=470efd06824232321e3d34f01adcfd94512c4aea;p=synfig.git Rename the Random class in the mod_noise module to RandomNoise to stop it clashing with the Random class in mod_particle. Also rename the files random.h and random.cpp. git-svn-id: https://synfig.svn.sourceforge.net/svnroot/synfig@2286 1f10aa63-cdf2-0310-b900-c93c546f37ac --- diff --git a/synfig-core/trunk/po/POTFILES.in b/synfig-core/trunk/po/POTFILES.in index 57ac37e..c37c4cf 100644 --- a/synfig-core/trunk/po/POTFILES.in +++ b/synfig-core/trunk/po/POTFILES.in @@ -129,8 +129,8 @@ src/modules/mod_noise/distort.h src/modules/mod_noise/main.cpp src/modules/mod_noise/noise.cpp src/modules/mod_noise/noise.h -src/modules/mod_noise/random.cpp -src/modules/mod_noise/random.h +src/modules/mod_noise/random_noise.cpp +src/modules/mod_noise/random_noise.h src/modules/mod_noise/valuenode_random.cpp src/modules/mod_noise/valuenode_random.h src/modules/mod_openexr/main.cpp diff --git a/synfig-core/trunk/src/modules/Makefile.am b/synfig-core/trunk/src/modules/Makefile.am index 11cb997..5cd0e01 100644 --- a/synfig-core/trunk/src/modules/Makefile.am +++ b/synfig-core/trunk/src/modules/Makefile.am @@ -3,7 +3,7 @@ synfiglibdir=@SYNFIGLIB_DIR@ MAINTAINERCLEANFILES=Makefile.in -SUBDIRS=mod_particle mod_filter mod_yuv420p mod_gif mod_gradient mod_geometry mod_noise mod_libavcodec mod_jpeg mod_openexr mod_bmp mod_ppm mod_png mod_dv mod_imagemagick mod_ffmpeg lyr_freetype lyr_std mod_mng mod_magickpp example +SUBDIRS=mod_particle mod_filter mod_yuv420p mod_gif mod_gradient mod_geometry mod_noise mod_jpeg mod_openexr mod_bmp mod_ppm mod_png mod_dv mod_imagemagick mod_ffmpeg lyr_freetype lyr_std mod_mng mod_magickpp example EXTRA_DIST=untemplate.nsh template.nsh example/simplecircle.h example/simplecircle.cpp example/filledrect.h example/main.cpp example/Makefile.am example/filledrect.cpp example/metaballs.cpp example/metaballs.h mod_mng/trgt_mng.h mod_mng/unmod_mng.nsh mod_mng/main.cpp mod_mng/Makefile.am mod_mng/mod_mng.nsh mod_mng/trgt_mng.cpp mptr_mplayer/main.cpp mptr_mplayer/mptr_mplayer.h mptr_mplayer/Makefile.am mptr_mplayer/mptr_mplayer.cpp mod_magickpp/trgt_magickpp.h mod_magickpp/unmod_magickpp.nsh mod_magickpp/main.cpp mod_magickpp/Makefile.am mod_magickpp/mod_magickpp.nsh mod_magickpp/trgt_magickpp.cpp sysconf_DATA = synfig_modules.cfg diff --git a/synfig-core/trunk/src/modules/mod_noise/Makefile.am b/synfig-core/trunk/src/modules/mod_noise/Makefile.am index 33717b7..2a766c5 100644 --- a/synfig-core/trunk/src/modules/mod_noise/Makefile.am +++ b/synfig-core/trunk/src/modules/mod_noise/Makefile.am @@ -7,7 +7,7 @@ INCLUDES = -I$(top_builddir) -I$(top_srcdir)/src moduledir=@MODULE_DIR@ module_LTLIBRARIES = libmod_noise.la -libmod_noise_la_SOURCES = random.cpp random.h distort.cpp distort.h noise.cpp noise.h valuenode_random.cpp valuenode_random.h main.cpp +libmod_noise_la_SOURCES = random_noise.cpp random_noise.h distort.cpp distort.h noise.cpp noise.h valuenode_random.cpp valuenode_random.h main.cpp libmod_noise_la_CXXFLAGS = @SYNFIG_CFLAGS@ libmod_noise_la_LIBADD = ../../synfig/libsynfig.la @SYNFIG_LIBS@ libmod_noise_la_LDFLAGS = -module -no-undefined -avoid-version diff --git a/synfig-core/trunk/src/modules/mod_noise/distort.cpp b/synfig-core/trunk/src/modules/mod_noise/distort.cpp index 1dc1af4..1660c7d 100644 --- a/synfig-core/trunk/src/modules/mod_noise/distort.cpp +++ b/synfig-core/trunk/src/modules/mod_noise/distort.cpp @@ -66,7 +66,7 @@ NoiseDistort::NoiseDistort(): size(1,1) { set_blend_method(Color::BLEND_STRAIGHT); - smooth=Random::SMOOTH_COSINE; + smooth=RandomNoise::SMOOTH_COSINE; detail=4; speed=0; random.set_seed(time(NULL)); @@ -85,8 +85,8 @@ NoiseDistort::color_func(const Point &point, float /*supersample*/,Context conte int i; Time time; time=speed*curr_time; - Random::SmoothType temp_smooth(smooth); - Random::SmoothType smooth((!speed && temp_smooth == Random::SMOOTH_SPLINE) ?
