I'm trying to rotate a string file by utilizing flash.geom.matrix but I'm clueless. How do you essentially input data into a matrix? I know that you can input data into a, b, tx, ty, etc. but these affect skewing, enlarging, and other stuff. I simply just want to create a M X N matrix with some data that can be rotated. Any help? ...
Is it possible to slowly rotate parts of a page (in this case a single class) via CSS? My current code: .c1 { -webkit-transform: rotate(170deg); -moz-transform: rotate(170deg); -o-transform: rotate(170deg); } Unfortunately there is no way to use javascript for this, with the amount of access I have. Is there a way to rotate this c...
I am currently rotating a UIImageView by touching, dragging, and releasing. I am rotating the object by the function: -(void)rotateForTime:(CGFloat)time distance:(CGFloat)distance { CABasicAnimation* rotationAnimation; rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"]; rotationAnimation.toVa...
I have a partial answer. Starting with: newHeight = Height * cos(radians) + Width * sin(radians) newWidth = Height * sin(radians) + Width * cos(radians) I can reverse the equations to get: temp = sqr(cos(radians)) - sqr(sin(radians)) Height = newHeight * cos(radians) - newWidth * sin(radians) / temp Width = newWidth * cos(radians)...
I have an iPad Split View Application that brings up a modal view to display certain content. When I bring up the modal (in PageSheet style) and then change from Portrait to Landscape (or vice-versa) and then dismiss the modal the orientation of the detailViewController (the parent of the modal) turns 90 degrees. So if I am in landscape...
Hello, I have an object which has a position, a rotation angle and a scale (x and y). The overall transform matrix is as follows : QTransform xform; xform.translate(instance.definition.position.x, instance.definition.position.y); xform.rotateRadians(instance.definition.rotation); xform.scale(instance.definition.scale.x, instance.defini...
I found some good resources for rotating a bitmap in android here and elsewher eon the net. I am close to getting my code to work but apparently I don't fully understand how the Matrix Translations work. The following is three main functions from my sprite class. THey worked great before I added things to facilitate the matrix rotatio...
I'm currently just bliting a rotation matrix onto the screen. The source of which is "RT" from; SensorManager.getRotationMatrix(Rt, I, accels, mags); Where accels and mags are from the sensors. The getRotationMatrix, and its display, are triggered once for every update of the acceleration sensor. Question; How often should get...
In my UIViewController class, I created an UIImagePickerController like this : -(BOOL)startCameraPickerFromViewController{ if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) return NO; UIImagePickerController* picker = [[UIImagePickerController alloc] init]; picker.sourceType = UII...
Hi, I am working on a image editing tool where user can pan / rotate and zoom the image. I am using Matrix to apply rotation and zooming effects. Now the probelm is that if image is not rotated, its panning works perfectly. But once the user rotates it, panning functionality goes for a toss. Here's the line of code i am using to drag (p...
Hello, I have a UIViewController that inherits all the delegation for the UITable. I have a UITableView called table that is set in my simple_tableViewController.h. I have set - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } but the main view rotates but the table does ...
Hi gang, I am trying to do a very simple animation, but it is giving me much grief... I must be doing some simple thing wrong and just missing by a bit my desired result. As posted here: Rotating around a diagonal axis I was trying to re-create a "Reversi" piece - a square which when activated would rotate about the axis Y=X, and cha...
I am making an Ipad app and im not using the views and view controllers (Except to call my own openGl drawing funcitons) I want the app to be able to change its drawing orientation depending on how the device is held. However with the research that ive done all I can find is how to do it through view controllers and accelerometers. Is ...
Hello, I am working on an app (my first one), which is basically a TabBar app. To be more precise there are: - a login view controller - a tab bar controller (when login is done) - a landscape view controller that is used when the first itel of the TabBar is switch from Portrait to Landscape. So, when I am in the first tab, I need to ...

I have a UINavigationController (Parent) that is pushing a UIViewController (Child). I understand that both need to support: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return YES; //(interfaceOrientation == UIInterfaceOrientationPortrait)...
I'm trying to have one of the children views in my screen (owned by one view controller) not rotate when the device rotates. My view controller allows rotations as it should, and I'm trying to apply a 90-degree rotation to the one "stationary" view to counteract the overall rotation. Problem is, everything seems to rotate anyways, and t...
When the app first loads the table and cells are correct. When you rotate to landscape mode the table cells look like they are still set up for portrait mode. When you rotate back to portrait the table cells are set up for landscape mode. Is there any way to manage this in the code? Thanks ...

When the view gets loaded it is in portrait mode so part of the view is missing and I can see the main view on the right hand side. If I load the subview in portrait mode then rotate the iPhone it rotates to landscape no problem. I have googled this lots and it seems ...
