i need matrix operations. i'm trying achieve is: scale down move specific position rotate degree (in center of bitmap) my code looks this: matrix matrix = new matrix(); matrix.prerotate(mship.getrotation(), mship.getx() + mship.getcurrentbitmap().getwidth()/2f, mship.gety() + mship.getcurrentbitmap().getheight()/2f); matrix.setscale((1.0f * mship.getwidth() / mship.getcurrentbitmap().getwidth()), (1.0f * mship.getheight() / mship.getcurrentbitmap().getheight())); matrix.posttranslate(mship.getx(), mship.gety()); mcanvas.drawbitmap(mship.getcurrentbitmap(), matrix, mbasicpaint); but rotation has wrong center, , can't figure out how solve - i've looked around on did find similar problems, no solutions this. think might have apply 1 of operations one's values executed in sequence cant figure out how to. try code: matrix matrix = new matrix(); matrix.settranslate(-mship.getcurrentbitmap...

(what people have against hello?) i have class extends bufferedimage : public class namedimage extends bufferedimage{ string name; public namedimage(int width, int height, int imagetype) { super(width, height, imagetype); } public void setname(string text){ name = text; } } before had this, got images with: image image = imageio.read(res); now, want translate namedimage , following tries don't work: namedimage image = imageio.read(res); namedimage image = (namedimage) imageio.read(res); how can achieve want do? why can't cast buffered image class, extends custom class? (what people have against thank you?) here's possibility, if want imageio use specific subclass. however, if want give name, i'd use @andrewthompsons suggestion map<string, bufferedimage> , because it's less verbose. imageinputstream stream = imageio.createimageinputstream(res); iterator<imagereader> readers = imageio.getim...

there thread detecting webp support using client-side. how detect webp support using server side? today, should check accept header image/webp . browsers support webp send part of accept string requests (images , non-images). in short: if( strpos( $_server['http_accept'], 'image/webp' ) !== false ) { // webp supported! } (you might want use preg_match instead , add word boundary checks , case insensitivity, in real world should fine) here's original answer several years ago, when above not reliable the "proper" way check accept header sent, bug in chrome means won't list image/webp though support it. this relevant forum thread: https://groups.google.com/a/webmproject.org/forum/#!topic/webp-discuss/6nyupcsaors which links bugtracker: https://code.google.com/p/chromium/issues/detail?id=169182 in turn links one: https://code.google.com/p/chromium/issues/detail?id=267212 end result? while isn't implemented yet, go...
