Comment on Peak Oil Doomsday… Apocolypse no? by badpirate

J Lee – Not given up. We are making many more strides in the right direction. Technology moves pretty quickly. Solar and Battery (Lithium-whatever) technology seems to have taken a lead at the moment, but I’m not really sure if the rare earth minerals required for their production are as sustainable as we’d like. I think that many environmentalists were pacified by Obama taking office (Right around the time I was making this post originally), in hopes that he would have a more progressive energy policy then his predecessor…. and we were right ($90 billion for green energy). But the problem is not gone yet for sure.

I’m not the woman in the video, but her video stirred me into some momentary activism. And at the very least, I added to the noise of people demanding change on the subject. And will continue to do so as needed.

Consider this my +1 to you since you don’t have a G+ button with which I could otherwise commend you.

OK, obviously, the EXIF data (eg reorientation) should not be applied to the image data. I’m also using a non-lazy loading image method (via an UIImage category) that ignores the orientation and the other meta data…

Good job!
I’m using this code to get the image data:

NSData *imageData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageSampleBuffer];
UIImage *image = [[UIImage alloc] initWithData:imageData];
self.stillImage = [self scaleAndRotateImage:image];

I find it really interesting that the EXIF information is stored unused in the UIImage (as I understand):

UIImageOrientation orient = image.imageOrientation;
switch(orient) {

How can I know if the reorientation is already applied to the image data or not?

Sorry… It never panned out. I pitched the idea to the other party and the decided to just go with posting the source as a new application (screw the customers). Meh. I think it would work though

Hi Kevin,

Regarding what you said at the end of: http://stackoverflow.com/a/6024688/997905 what was the result? did Apple finally approved the app update? The curiosity is killing me

Thanks, have a nice day!
