Not getting transparent background while rotating an image
php,image,image-processing,imagemagick,image-rotation
Following command worked for me on Debian wheezy 7.5 with mageMagick 6.7.7-10. convert -background "rgba(0,0,0,0)" -rotate 5 images.jpg new.png Specify -background "rgba(0,0,0,0)" it will set transparent background fill for output image. Also make sure to save output image in .png format (which supports transparency) Hope It will help. :) Note:...
I imrotate() an image, draw two lines, rotate back the lines and draw them in orginal image, but don't get the expected result in MATLAB?
matlab,rotation,translation,image-rotation
I found the solution ! Well, what happens is that the built-in function imrotate does not only rotate by default the image, but it does also a translation so that the rotated-image fit in the figure. the solution is to use : I_R = imrotate(I,-45,'nearest','crop'); the important parameter here is...
Java Rotate Image function [closed]
Change if (spiral == null){ spiral = getImage("spiral.jpg"); spiral.rotateImage(45, this); } To if (spiral == null){ spiral = getImage("spiral.jpg"); rotateImage(45, this); } since rotateImage is your own method not an Image method...
Using NSAffineTransform to rotate NSImage results in a file twice the size
objective-c,cocoa,nsimage,image-rotation,nsaffinetransform
I still don't know the root cause of this, but one work around is to save to the JPEG representation instead of the TIFF. The method I wrote is as follows : - (void)CompressAndSaveImg:(NSImage *)img ToDiskAt:(NSString *)path WithCompressionFactor:(float)value{ NSData *imgData = [img TIFFRepresentation]; NSBitmapImageRep *imgRep = [NSBitmapImageRep imageRepWithData:imgData]; NSNumber *compressionFactor...
Image rotation happens too often
java,math,rotation,game-physics,image-rotation
I'm assuming your Graphics2D object is an instance of java.awt.Graphics2D. That said, I think I know your problem: You're using degrees when the documentation for rotate() specifies that you should be passing in a value in radians. As a measurement in degrees is on a very different scale than one...
how i can rotate image by array of byte in java?
java,arrays,byte,raster,image-rotation
After some work, I came up with this: public class ImageRotation { public static void main(String[] args) throws IOException { BufferedImage img = ImageIO.read( ImageRotation.class .getResourceAsStream("Capture.PNG")); JPanel pane = new JPanel(); pane.setLayout(new BorderLayout()); pane.add( new JLabel("Original", new ImageIcon(img), JLabel.CENTER), BorderLayout.WEST); pane.add( new JLabel("Rotated", new ImageIcon(rotateClockwise(img)), JLabel.CENTER), BorderLayout.EAST); JFrame frame =...
Monogame rotating a sprite
Answer: in the new Vector2(x, y) I just had to set x and y values that are within the image.
Rotate an Imagewith Animation
android,android-animation,android-imageview,image-rotation
First of all, what is you minimum SDK requirement? In case it's at least Android 3.0, you can use the newer animation framework, and animate your Image with something like this: imageView.animate().rotation(180).start(); About the flicker: I wouldn't reset the source image of the ImageView after the rotation, I'd just leave...
I have 3 images that do rotate but they don't go back to the 1st one and start over
jquery,css,image,image-rotation
There are many issues with the code, $('#hero div: first'); - Unrecognized expression. It should be $('#hero div:first'); - Notice the space. Change the setInterval call to setInterval(rotateImages,3000);. The reason is "rotateImages()" runs in a global scope. Refer ...
Can we rotate an image in MATLAB filled with background color of original image?
matlab,rotation,image-rotation
Here's a naive approach, where we simply apply the same rotation to a mask and take only the parts of the rotated image, that correspond to the transformed mask. Then we just superimpose these pixels on the original image. I ignore possible blending on the boundary. A = imread('cameraman.tif'); angle...
Rotating BufferedImage in Java without change size
java,image-processing,image-rotation
Rotating a non-square image within the same boundaries will crop the image. You could change the Graphics clipping bounds, but this is dangerous, as you could actually end up painting outside of the visible bounds available to the Graphics context, which results in some very weird and generally not welcomed...
Rotate image by x degrees? - Java [duplicate]
java,image,rotation,image-rotation
I'm not an expert myself but this might help: Java: Rotating Images Here's their answer: `// The required drawing location int drawLocationX = 300; int drawLocationY = 300; // Rotation information double rotationRequired = Math.toRadian(45); double locationX = image.getWidth() / 2; double locationY = image.getHeight() / 2; AffineTransform tx =...
Java - rotate image in place
Okay, assuming that the turret and base are separate images, and the turret isn't the same size as the tank (cause then it becomes complicated....more then it actually is :P) You can use a AffineTransform and compound the transformations... // This is the x/y position of the top, at the...
Is there any easy way to rotate an image about z axis using java without jumping into java 3d?
If you are referring to rotating an image during a Swing paint operation, then the correct way to do this is with an AffineTransform. Graphics2D graphic; graphic.drawRenderedImage(image, AffineTransform.getRotateInstance(Math.PI)); Unfortunately AffineTransform does not support perspective transforms (by definition a transform is only Affine if parallel lines remain parallel). For perspective transforms...
Rotate raw pixel data of an image 180 degrees
c#,image,dicom,image-rotation,clearcanvas
It took a while, but I ended up solving my problem by using a method from a Java library. You can see the class here. string file = @"adicomfile.dcm"; DicomFile df = new DicomFile(); df.Load(file); // Get the amount of bits per pixel from the DICOM header. int bitsPerPixel =...
Rotate and move UIImageView at the same time
objective-c,animation,uiimageview,uiimage,image-rotation
You can do translate and rotation together using successive CGAffineTransformations. - (void)transformImageView { CGAffineTransform transform = CGAffineTransformIdentity; float translateX = orbitRadius * cos(orbitAngle * M_PI / 180); float translateY = orbitRadius * sin(orbitAngle * M_PI / 180); CGAffineTransformTranslate(transform, translateX, translateY); CGAffineTransformRotate(transform, rotateDegree * M_PI / 180); orbitObject.transform = transform; }...
