From 014aa7261e29810b35b3d65c759f9d255bf8a277 Mon Sep 17 00:00:00 2001 From: Ton Roosendaal Date: Mon, 9 Jan 2006 00:40:35 +0000 Subject: Orange branch: OpenEXR finally in Blender! Credits go to Gernot Ziegler, who originally coded EXR support, and to Austin Benesh for bringing it further. Kent Mein provided a lot of code for integrating float buffers in Blender imbuf and ImBuf API cleanup, and provided Make and Scons and static linking. At this moment; the EXR libraries are a *dependency*, so you cannot get the Orange branch compiled without having OpenEXR installed. Get the (precompiled or sources) stuff from www.openexr.com. Current default is that the headers and lib resides in /user/local/ Several changes/additions/fixes were added: - EXR code only supported 'half' format (16 bits per channel). I've added float writing, but for reading it I need tomorrow. :) - Quite some clumsy copying of data happened in EXR code. - cleaned up the api calls already a bit, preparing for more advanced support - Zbuffers were saved 16 bits, now 32 bits - automatic adding of .exr extensions went wrong Imbuf: - added proper imbuf->flags and imbuf->mall support for float buffers, it was created for *each* imbuf. :) - found bugs for float buffers in scaling and flipping. Code there will need more checks still - imbuf also needs to be verified to behave properly when no 32 bits rect exists (for saving for example) TODO: - support internal float images for textures, backbuf, AO probes, and display in Image window Hope this commit won't screwup syncing with bf-blender... :/ --- source/blender/blenkernel/intern/writeavi.c | 19 ++++++++----------- 1 file changed, 8 insertions(+), 11 deletions(-) (limited to 'source/blender/blenkernel/intern/writeavi.c') diff --git a/source/blender/blenkernel/intern/writeavi.c b/source/blender/blenkernel/intern/writeavi.c index 77c35cc46ab..35f5c7b0d17 100644 --- a/source/blender/blenkernel/intern/writeavi.c +++ b/source/blender/blenkernel/intern/writeavi.c @@ -35,10 +35,6 @@ #include -#ifdef HAVE_CONFIG_H -#include -#endif - #include "MEM_guardedalloc.h" #include "BLI_blenlib.h" @@ -122,7 +118,8 @@ void start_avi(void) void append_avi(int frame) { - unsigned int *rt1, *rt2, *temp; + unsigned int *rt1, *rt2; + struct ImBuf *temp; int y; if (avi == NULL) { @@ -130,20 +127,20 @@ void append_avi(int frame) return; } - /* note that libavi free's the buffer... stupid interface - zr */ - temp = MEM_mallocN(R.rectx*R.recty*4, "append_avi buf"); + /* note that libavi free's the buffer... stupid interface - zr */ + temp = IMB_allocImBuf(R.rectx,R.recty*4,32, IB_rect, 0); - rt1= temp; + rt1= temp->rect; rt2= R.rectot + (R.recty-1)*R.rectx; for (y=0; y < R.recty; y++, rt1+= R.rectx, rt2-= R.rectx) { memcpy (rt1, rt2, R.rectx*4); } - IMB_convert_rgba_to_abgr(R.rectx*R.recty, temp); + IMB_convert_rgba_to_abgr(temp); - AVI_write_frame (avi, (frame-sframe), AVI_FORMAT_RGB32, - temp, R.rectx*R.recty*4); + AVI_write_frame (avi, (frame-sframe), AVI_FORMAT_RGB32, temp->rect, R.rectx*R.recty*4); printf ("added frame %3d (frame %3d in avi): ", frame, frame-sframe); + IMB_freeImBuf(temp); } void end_avi(void) -- cgit v1.2.3
