flex4 - Flex font rendering differences from 4.1 to 4.5 -

-

i'm upgrading app flex 4.1 4.5

we've noticed arial font rendered differently between 2 versions when used @ small sizes.

here's simple app example:

<?xml version="1.0" encoding="utf-8"?> <s:application xmlns:fx="http://ns.adobe.com/mxml/2009"                 xmlns:s="library://ns.adobe.com/flex/spark"                 xmlns:mx="library://ns.adobe.com/flex/mx" minwidth="955" minheight="600">     <fx:style>         @namespace s "library://ns.adobe.com/flex/spark";         @namespace mx "library://ns.adobe.com/flex/mx";         @font-face {              src: url("/assets/fonts/arial.ttf");              fontfamily: arial;              embedascff: true;          }         @font-face {              src: url("/assets/fonts/arialbd.ttf");              fontfamily: arial;              embedascff: true;              font-weight: bold;         }         global         {             font-family: arial;         }     </fx:style>     <s:label text="hello world" fontweight="bold" x="20" y="20"  /> </s:application>

when run against 2 different sdks, here's image of font rendering get:

example of font issues

note in 4.5 font looks squashed.

what's cause of this, , how resolve it?

my best guess it's related the changes made support fonts on handheld devices. fix may have play around style sheet settings bit.

css media queries
can use @media rules in style sheets filter css rules based on device’s dpi classification. there 2 properties can filter on currently, os-platform , application-dpi. here’s example of filtering on them set button font instance (from adobe’s prerelease docs):

@media (os-platform: "android") , (application-dpi: 240) { s|button {      fontsize: 10; }

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
