| 2023-04-08 | libc: Add poolreset() function | cinap_lenrek | |
| This is intended for the secrmem pool in the kernel, but could also be used for temporary pools to recover the memory used by the arenas. | |||
| 2023-02-06 | libmemdraw: don't return Buffer copy from calc functions | cinap_lenrek | |
| The calc functions get their buffers passed by value. This is convenient as the code usually modifies the buffers during iteration. However, making ANOTHER copy (odst) and returning it at the end is a bit silly. We already made a copy when passing the arguments, and the caller of the calc function can just reuse the copy it already has. So changing the return type from Buffer to void. | |||

| 2019-03-09 | libmemdraw: remove static Point p00 and use ZP instead | cinap_lenrek | |
| 2019-03-09 | libmemdraw: handle memarc() phi == 0 and phi <= -360, keep alpha in bounds | cinap_lenrek | |
| 2017-04-29 | libmemdraw: get rid of kernel iprint() emulation | cinap_lenrek | |
| 2017-04-29 | libmemdraw/libmemlayer: get rid of drawdebug prints | cinap_lenrek | |
| 2016-11-17 | libmemdraw: cleanup fillpoly(), remove unused fillcolor hack | cinap_lenrek | |
| 2016-11-17 | libmemdraw: remove unused static drawbuf variables and ptrfn() declaration | cinap_lenrek | |
| 2016-05-29 | libmemdraw: remove unused static variable from memimagedraw() | cinap_lenrek | |
| 2015-03-01 | libdraw: use readn() to read headers and Fontchar array | cinap_lenrek | |
| the Fontchar array might be bigger than the i/o unit, so we have to use readn() to properly read it. | |||
| 2015-02-24 | libdraw: check fontchar count in openmemsubfont() and readsubfont() | cinap_lenrek | |
| 2014-12-30 | libmemdraw: never point Buffer.alpha to nil (thanks mischief) | cinap_lenrek | |
| the boolcopy optimization doesnt doesnt use Buffer.alpha, tho the debug function dumpbuf() still can dereference it. to keep it simple, always have Buffer.alpha point to the channel or &ones when not used. | |||
| 2014-12-28 | libmemdraw: fix fd leak in openmemsubfont and memory leak in freememsubfont | mischief | |
| 2014-09-19 | libmemdraw: fix byte ordering in memfillcolor() | cinap_lenrek | |
| memfillcolor() used to write longs in host byte order which is wrong. have to always use little endian. to simplify, moved little endian conversion into memsetl() and memsets() avoiding code duplication. | |||
| 2014-09-14 | libmemdraw: update drawtest to use same rounding in alpha calculation as ↵ | cinap_lenrek | |

| 2014-04-12 | libmemdraw: improve readbyte() and writebyte() routines | cinap_lenrek | |
| remove unused memsetb() routine. replace foo ? 1 : 0 with foo != 0 avoid double calculation of rgb components in readbyte() handle byte aligned color components in writebyte() which lets us avoid the read-modify-write and the shifting. surprisingly, the branches in the loop are way less important than avoiding the memory access. this change makes ganes/snes playable at -3 scaling. | |||
| 2014-02-01 | libmemdraw: apply erik quanstros fix for sign preserving in byteaddr() | cinap_lenrek | |
| 2013-12-09 | draw: fix drawing of replicated source image on memlayer with a clip rectangle | cinap_lenrek | |
| when a replicated source image with a clipr with clipr.min > Pt(0, 0), drawclip() would properly translate the src->clipr on the dstr but then clamp the source rectangle back on src->r. while traversing down multiple layers, this would cause the translation to be applied multiple times to the dst rectangle giving the wrong image result. this change adds a new drawclipnorepl() function that avoids the clamping of source and mask rectangles to src->r and mask->r. this is then used in libmemlayer. the final memimagedraw() call will call drawclip() which will do the final claming. a testcase is provided: #include <u.h> #include <libc.h> #include <draw.h> Image *blue; Image *red; void main(int, char *argv[]) { Image *i; if(initdraw(nil, nil, argv[0]) < 0) sysfatal("initdraw: %r"); i = allocimage(display, screen->r, screen->chan, 1, DWhite); red = allocimage(display, Rect(0,0,1,1), screen->chan, 1, DRed); blue = allocimage(display, Rect(0,0,1,1), screen->chan, 1, DPaleblue); replclipr(red, 1, Rect(10, 10, 110, 110)); replclipr(blue, 1, Rect(11, 11, 111, 111)); /* draw on non-layer, works correctly */ draw(i, i->r, red, nil, ZP); draw(i, i->r, blue, nil, ZP); draw(screen, screen->r, i, nil, i->r.min); flushimage(display, 1); /* draw on (screen) layer is too far to the right */ draw(screen, screen->r, red, nil, ZP); draw(screen, screen->r, blue, nil, ZP); flushimage(display, 1); for(;;){ sleep(1000); } } | |||

| 2013-06-16 | draw: add badrect() function to reject zero, negative size or orverly huge ↵ | cinap_lenrek | |
| rectangles not checking the rectangle dimensions causes integer overflows and memory corruption. adding a new badrect() function that checks for these cases. | |||
