php - Center image inside image using imagecopy function -


i have simple script adds image inside image. here code:

<?php  $im = imagecreatetruecolor(650, 400); $stamp = imagecreatefrompng('test.png');  $red = imagecolorallocate($im, 209, 231, 244); imagefill($im, 0, 0, $red);  $marge_right = 10; $marge_bottom = 133; $sx = imagesx($stamp); $sy = imagesy($stamp);  imagecopy($im, $stamp, imagesx($im) - $sx - $marge_right, imagesy($im)  - $sy - $marge_bottom, 0, 0, imagesx($stamp), imagesy($stamp));  header('content-type: image/png'); imagepng($im); imagedestroy($im);   ?>

now place test image 10x right of big image , 133px bottom of image. how place image centered vertically depending on height??

thanks

$marge_right , $marge_bottom should correspond difference of horizontal , vertical sizes (respectively) between source , destination images.

so need calculate difference way:

$marge_right = abs($dest_sx-$src_sx); $marge_bottom = abs($dest_sy-$src_sy);

the abs optional if sure source bigger source smaller destination.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
