[2007-12-09 14:16:49] <Erica> Ugh ugh ugh
[2007-12-09 14:16:51] <Erica> CGImageRef
[2007-12-09 14:16:54] * Erica breaks out in hives
[2007-12-09 14:16:57] <Erica> UIImage dude
[2007-12-09 14:16:57] <Drunknbass> the captured frame is in the header
[2007-12-09 14:17:07] <Drunknbass> i didnt need a *
[2007-12-09 14:17:14] <Erica> (UIImage *) is the same as cGImageRef
[2007-12-09 14:17:22] <Erica> I HATE CORE FOUNDATION
[2007-12-09 14:17:32] <lduncan> really? exactly the same?
[2007-12-09 14:17:38] <Erica> Yes, it's called toll free bridging
[2007-12-09 14:17:43] <lduncan> ahh
[2007-12-09 14:17:46] <Erica> google it
[2007-12-09 14:18:08] <Erica> http://www.google.com/search?hl=en&q=cgimageref+toll+free+bridging&btnG=Google+Search
[2007-12-09 14:18:18] <lduncan> yeah i know, never new it applied to uiimage

[2007-12-09 14:18:52] <Erica> Hi Ste
[2007-12-09 14:18:54] <Erica> I'm besmirching Core Foundation
[2007-12-09 14:18:57] <Erica> blooey
[2007-12-09 14:19:06] <Ste> heh
[2007-12-09 14:19:09] <lduncan> :D
[2007-12-09 14:19:31] <Drunknbass> are you sure.. so anything that wants a CGImageRef i can use UIImage?

[2007-12-09 14:20:40] <lduncan> apparently so, that's the idea of toll free bridging

[2007-12-09 14:21:53] <Erica> What were you all asking?
[2007-12-09 14:22:08] <Darken> yea
[2007-12-09 14:22:21] <Darken> [22:19] <Drunknbass> are you sure.. so anything that wants a CGImageRef i can use UIImage?
[2007-12-09 14:22:35] <Drunknbass> well if i switch it to uiimage i get this warning: target of assignment not really an lvalue; this will be a hard error in the future... and...
[2007-12-09 14:22:41] <Erica> Yes, Darken
[2007-12-09 14:22:51] <Erica> You can't switch it to UIImage. It has to be (UIImage *)
[2007-12-09 14:22:53] <Darken> i didnt ask
[2007-12-09 14:22:57] <Darken> just relaying for ya
[2007-12-09 14:23:01] <Erica> Ah.
[2007-12-09 14:23:01] <Drunknbass> warning: assignment from incompatible pointer type

[2007-12-09 14:23:57] <Erica> My bad
[2007-12-09 14:24:12] <Erica> I'm looking at the headers
[2007-12-09 14:24:15] <Erica> And they are not toll free bridge
[2007-12-09 14:24:16] <Erica> d
[2007-12-09 14:24:18] <Erica> I'm wrong
[2007-12-09 14:24:21] <Erica> UIImage *foo

[2007-12-09 14:24:27] <lduncan> i was suspect ;-)

[2007-12-09 14:24:32] <Drunknbass> :(
[2007-12-09 14:24:44] <Erica> foo = [UIImage initWithImageRef:imageref];
[2007-12-09 14:24:55] <Erica> UIImage contains other stuff along with the image ref
[2007-12-09 14:25:01] <lduncan> yeah that's better
[2007-12-09 14:25:20] <Erica> You can also init with an orientation
[2007-12-09 14:25:29] <Erica> - (id)initWithImageRef:(struct CGImage *)fp8 orientation:(int)fp12;
[2007-12-09 14:25:31] <Drunknbass> so how can i fix this so the warning goes away CGImageRef *lowRes = [(id)capturedFrame createLowResolutionFullScreenCGImageRef];
[2007-12-09 14:25:40] <lduncan> does that rotate the view, or the image pixels?
[2007-12-09 14:25:57] <Erica> Dunno, lduncan
[2007-12-09 14:25:58] <Erica> I've used UIImageView in Sensors.app
[2007-12-09 14:26:02] <Erica> With rotating view
[2007-12-09 14:26:09] <Erica> But I haven't tried with UIImage
[2007-12-09 14:26:26] <lduncan> Drunknbass: you need to dereference capturedFrame in the line above where you init it

[2007-12-09 14:27:44] <lduncan> you had: CGImageRef capturedFrame = [mainWindow _createCGImageRefRepresentationInFrame: _contentRect];
[2007-12-09 14:27:49] <lduncan> should be CGImageRef *capturedFrame = [mainWindow _createCGImageRefRepresentationInFrame: _contentRect];
[2007-12-09 14:27:50] <Erica> Drunkenbass: I know you can rotate UIImageView, and have done so (code sample above) but I haven't tried setting the orientation in UIImage
[2007-12-09 14:27:57] <Drunknbass> ooo the *
[2007-12-09 14:27:58] <Drunknbass> in lowRes
[2007-12-09 14:28:06] <Erica> lduncan: Are you sure?
[2007-12-09 14:28:14] <Erica> Usually anything that ends with "ref" is a ref already
[2007-12-09 14:28:18] <Erica> Doesn't need the extra *
[2007-12-09 14:29:03] <lduncan> true erica, no * for refs
[2007-12-09 14:29:13] <Erica> CGImageRef newimg = CGImageCreateWithImageInRect(coreimage, CGRectMake(0.0, 0.0, IMAGE_WIDTH, IMAGE_HEIGHT));
[2007-12-09 14:29:19] <Erica> That's from SendPics

[2007-12-09 14:29:43] <lduncan> yip, so drunk remove the * from lowRes
[2007-12-09 14:29:59] <Drunknbass> k
[2007-12-09 14:30:39] =-= lokkju_ is now known as lokkju
[2007-12-09 14:30:41] <Erica> Why are you casting (id)?
[2007-12-09 14:30:47] <Erica> Isn't that kinda pointless/
[2007-12-09 14:30:52] <Drunknbass> cause it works with it
[2007-12-09 14:30:56] <Drunknbass> doesnt without it
[2007-12-09 14:31:03] <Erica> roger that
[2007-12-09 14:31:28] <Erica> But try it without the id when you take away the extra *
[2007-12-09 14:31:37] <Drunknbass> so at the end of this how can i make sure capturedFrame and lowRes are gone from memory
[2007-12-09 14:31:54] <Erica> release?
[2007-12-09 14:31:56] <Erica> But the iPhone seems to do pretty good garbage collection
[2007-12-09 14:32:22] <lduncan> objective 2.0 garbage collection?
[2007-12-09 14:32:23] <Drunknbass> i just want to make sure cause im running out of memory and crashing
[2007-12-09 14:32:28] <NerveGas> erica: UIImage has a method named imageRef, which returns a CGImage *
[2007-12-09 14:32:32] <Erica> CFRelease()
[2007-12-09 14:32:36] <NerveGas> instead of having to create it in CG
[2007-12-09 14:32:37] <Erica> Yeah, NerveGas, scroll up
[2007-12-09 14:33:02] <Erica> Erica: foo = [UIImage initWithImageRef:imageref];
[2007-12-09 14:33:10] <Erica> Erica: [foo imageRef];
[2007-12-09 14:33:25] <Drunknbass> well its not that simple im trying to access the camera data
[2007-12-09 14:33:27] <Drunknbass> i can only do it some ways
[2007-12-09 14:33:41] <Drunknbass> ilso without the id it says incompatible pointer type
[2007-12-09 14:33:47] <Erica> do you need to do outside the Photo framework?
[2007-12-09 14:34:18] <Drunknbass> i dunno, im trying different things
[2007-12-09 14:34:30] <lduncan> Erica i believe drunk is trying to emulate video capture?
[2007-12-09 14:34:31] <Erica> cc = [CameraController sharedInstance];

[2007-12-09 14:34:44] <Erica> [cc stopPreview];
[2007-12-09 14:34:45] <Drunknbass> i had to modify a header to even use createLowResolutionFullScreenCGImageRef
[2007-12-09 14:35:05] <Erica> Modding headers is part of iPhone programming life
[2007-12-09 14:35:09] <Erica> if you haven't modded headers, you haven't really programmed
[2007-12-09 14:35:15] <Erica> Until Apple debuts the SDK
[2007-12-09 14:35:15] <lduncan> :D
[2007-12-09 14:35:41] <lduncan> lets hope the documentation is complete
[2007-12-09 14:35:49] <Drunknbass> haha
[2007-12-09 14:36:36] <Drunknbass> my app compiles but then in console i see this error

[2007-12-09 14:49:08] <Drunknbass> yea
[2007-12-09 14:49:29] <lduncan> it doesn't work that way
[2007-12-09 14:49:57] <Erica> I think you have to actually be dealing with a real image
[2007-12-09 14:50:05] <Erica> Not just an alloc'ed, inited pointer
[2007-12-09 14:50:13] <Drunknbass> well this looks like it wants a cgimage http://idevdocs.com/function.php?f=21679
[2007-12-09 14:50:55] <lduncan> i think it just returns one from a CameraImage - whatever that is
[2007-12-09 14:51:17] <Erica> Have you tried -(void)cameraController:(id)sender tookPicture:(UIImage*)picture withPreview:(UIImage*)preview jpegData:(NSData*)jpegdata imageProperties:(struct __CFDictionary *)imageProps
[2007-12-09 14:51:34] <Drunknbass> i wasnt actually taking pics because it was too slow for video
[2007-12-09 14:51:35] <Erica> That's what I use for picSnap
[2007-12-09 14:51:42] <Drunknbass> im trying to do video tho
[2007-12-09 14:51:47] <Erica> Good luck with that
[2007-12-09 14:52:04] <Drunknbass> i can get it to work but i can only get 125 frames
[2007-12-09 14:52:11] <Erica> 125 frames?
[2007-12-09 14:52:12] <BHSPitLappy_> Thanks for everything, Erica :)
[2007-12-09 14:52:14] <Drunknbass> so i wanted to lower the quality of the cgimage im storing
[2007-12-09 14:52:15] <Erica> How many per second/
[2007-12-09 14:52:21] <Drunknbass> 40-45 ish
[2007-12-09 14:52:25] <Erica> You're welcome BHSP
[2007-12-09 14:52:31] <BHSPitLappy_> (First time seeing you on IRC, thought I'd get that in)
[2007-12-09 14:52:31] <Erica> That's very nice, drunknbass
[2007-12-09 14:52:49] <Erica> Are you sending them to disk?
[2007-12-09 14:52:53] <Drunknbass> it would be if i could lower the quality im storing of the image so i dont max the memory out soo fast
[2007-12-09 14:53:04] <Drunknbass> putting them in an array
[2007-12-09 14:53:05] <Erica> can you just paste the bit you're working on?
[2007-12-09 14:53:12] <Drunknbass> then after i will encode them
[2007-12-09 14:53:34] <Erica> Why not just dump to disk as images?
[2007-12-09 14:53:39] <Erica> At least while recording?
[2007-12-09 14:53:44] <Drunknbass> dont know how long that would take
[2007-12-09 14:54:03] <Drunknbass> you have a quick code i can use to dump a cgimage to disk
[2007-12-09 14:54:05] <lduncan> too long i'd suspect
[2007-12-09 14:54:10] <Drunknbass> i can have the filename increment with my array
[2007-12-09 14:54:11] <Erica> 15 fps is more than adequate for most video purposes
[2007-12-09 14:54:27] <Erica> If you're doing 40-45 fps, you' should have enough time
[2007-12-09 14:54:30] <Drunknbass> or with my loop
[2007-12-09 14:54:32] <Drunknbass> not array

[2007-12-09 14:56:34] <Drunknbass> thats what i have now
[2007-12-09 14:56:42] <Drunknbass> anything is ok
[2007-12-09 14:58:04] <Drunknbass> if i can dump the CGImage to disk and bypass the array and do it at a resonable speed ill bypass the ram limits
[2007-12-09 14:58:17] <Drunknbass> and will be limited by how fast i can dump the files to disk
[2007-12-09 14:58:46] <Drunknbass> or maybe use both
[2007-12-09 14:59:22] <Drunknbass> have the array dump the file to disk and then release that frame from memory as i have new frames being added to the array, like a buffer
[2007-12-09 14:59:55] <Erica> Do you have it as NSData at all?
[2007-12-09 15:00:09] <Drunknbass> nope
[2007-12-09 15:00:22] <Drunknbass> everything is really hacky right now
[2007-12-09 15:00:36] <Drunknbass> i have a nstimer that runs the function for 10 seconds

[2007-12-09 15:00:39] <Erica> In my code, I either use Apple's dump screen (produces tiff)
[2007-12-09 15:00:40] <anima> both array & dumping, that sounds good, especially if you can detect that the image is not changing so you have a moment to use a freeze frame.
[2007-12-09 15:00:41] <Drunknbass> with a .1 delay
[2007-12-09 15:00:45] <Erica> or the NSData from the callback
[2007-12-09 15:01:12] <Darken> anima the image will change constantly
[2007-12-09 15:01:22] <Drunknbass> well ill try anything to dump the image.. just make sure it can take a cgimage and export an imge from that and i can plug it right in
[2007-12-09 15:01:45] <anima> yep Darken, but by matter of degree is obviously what is meant.
[2007-12-09 15:02:01] <Darken> he won't easily calculate that
[2007-12-09 15:02:11] <anima> yeh , that's the rub
[2007-12-09 15:02:16] <Darken> not on the phone
[2007-12-09 15:02:20] <anima> if!

[2007-12-09 15:19:09] <Darken> # dd if=/dev/zero of=dump.raw bs=8192 count=10000
[2007-12-09 15:19:20] <Darken> 81920000 bytes (82 MB) copied, 21.6039 s, 1.8 MB/s
[2007-12-09 15:19:34] <Erica> CGImageWriteEXIFJPEGToPath([img imageRef], url);
[2007-12-09 15:20:11] <Darken> why is dd lieing to me
[2007-12-09 15:20:11] <_BigBoss_> there any way to change font size for only part of the text on a UITableCell row?
[2007-12-09 15:20:17] <Darken> telling me 1.8MB/s is a bunch of crap
[2007-12-09 15:20:30] <_BigBoss_> like I want to show EDGE then (ip address) where IP is small text font
[2007-12-09 15:20:47] <Erica> Add another text field to the row
[2007-12-09 15:20:47] <Erica> as a subview
[2007-12-09 15:20:57] <_BigBoss_> cool thanks Erica
[2007-12-09 15:21:06] <Erica> I'm sure there's a better way, but *shrug*
[2007-12-09 15:21:32] <_BigBoss_> anyway works for me :)
[2007-12-09 15:23:05] <Erica> night all
[2007-12-09 15:23:27] <Darken> im showing you can easily write 10 raw frames @ 640x480 to the flash drive per second
[2007-12-09 15:25:23] <Darken> almost 2fps of full 2MP images

[2007-12-09 15:25:45] <Darken> and if you can get any minimal sort of compression or processing on the images while writing to disk
[2007-12-09 15:25:55] <Darken> no problem to sustain more than that
[2007-12-09 15:27:39] <anima> g'night Erica.
