osx - original image size is not retained when it is exported as PDF using CGImageDestinationRef -

-

i developing desktop application supports exporting png image different image formats.

when export png image (refer first link) pdf format, appears shown in link2.

http://www.flickr.com/photos/36018837@n05/5472635835/ (original image) http://www.flickr.com/photos/36018837@n05/5473232908/ (exported image)

the image has become larger.

why happen? doing wrong in code? how solve this?

following code snippet use export: //filepath: destination path //exporttype: kuttypepdf

cgimagedestinationref imagedestination = cgimagedestinationcreatewithurl((cfurlref)filepath,(cfstringref )exporttype,1,null); bool success = no;

if( imagedestination != null ) { cgimageref imageref = [ inimage createcgimage ]; if( imageref != null ) { cgimagedestinationaddimage(imagedestination, imageref, null); success = cgimagedestinationfinalize(imagedestination); cgimagerelease(imageref ); } cfrelease( imagedestination ); }

thanks in advance.

regards, deepa

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
