opengl es - LibGDX - Sprite to Pixmap -

-

i using libgdx small app project, , need somehow take series of sprites , place them (or pixels rather) pixmap. basic idea take random sprites generated through various means while app running, and, @ specific times, merge of them onto single background sprite.

i believe of can done easily, step of getting sprite images pixmap isn't quite obvious me. sprites have various transparent , semi-transparent pixels, grabbing color @ each pixel while on same screen isn't applicable either, shouldn't take background colors it.

if there suitable alternative accomplish looking love hear it. highly appreciated.

i think want render sprites off-screen buffer (called "fbo" or framebuffer in libgdx) (blending them they're added), , render offscreen buffer screen single draw call? if so, question should help: libgdx spritebatch render texture

this requires opengl es 2.0, eliminate support older devices.

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
