c++ - DirectX9 texture shows up distorted -

-

for reason on machines conditionally (d3dptexturecaps_nonpow2conditional) supports "non power of two" (nonpow2) textures i'm getting kind of image distortion:

enter image description here

(on machines supports nonpow2 textures works fine.)

this 1280x720 resolution rgb24 (d3dfmt_x8r8g8b8).

i know there 4 rules when dealing conditionally supported textures:

1.the texture addressing mode texture stage set d3dtaddress_clamp.

mpdevice->setsamplerstate(0, d3dsamp_addressu, d3dtaddress_clamp);

mpdevice->setsamplerstate(0, d3dsamp_addressv, d3dtaddress_clamp);

mpdevice->setsamplerstate(0, d3dsamp_addressw, d3dtaddress_clamp);

2.texture wrapping texture stage disabled (d3drs_wrap n set 0).

mpdevice->setrenderstate(d3drs_wrap0, 0);

3.mipmapping not in use (use magnification filter only).

mpdevice->setsamplerstate(0, d3dsamp_mipfilter, d3dtexf_none);

4.texture formats must not d3dfmt_dxt1 through d3dfmt_dxt5.

i'm using d3dfmt_x8r8g8b8...

texture created this:

mpdevice->createtexture(width, height, 1, d3dusage_dynamic, d3dfmt_x8r8g8b8, d3dpool_default, &ptexture, nullptr);

and updated this:

d3dlocked_rect lockedrect;  ptexture->lockrect(0, &lockedrect, nullptr, d3dlock_discard);  // const ippisize roisize = { width, height };  // ippicopy_8u_c3ac4r((ipp8u*) ppixels, width * 3, (ipp8u*) lockedrect.pbits, width * 4, roisize);  // rgb rgba // ippicopy_8u_ac4c3r((ipp8u*) ppixels, width * 4, (ipp8u*) lockedrect.pbits, width * 3, roisize);  // rgba rgb  // temp.       unsigned char* pdst = (unsigned char*) lockedrect.pbits; const unsigned char* psrc = ppixels;  (int k = 0; k < width; k++) {    (int j = 0; j < height; j++)    {       pdst[0] = psrc[0];       pdst[1] = psrc[1];       pdst[2] = psrc[2];       pdst[3] = 255;        pdst += 4;       psrc += 3;    } }  ptexture->unlockrect(0);

does had similar problem? or have idea on going on?

maybe there's wrong rgb data itself?

thanks.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
