3. Rotate an image in image source in html - Stack Overflow

   stackoverflow.com/questions/20061774

   If your rotation angles are fairly uniform, you can use CSS: CSS: -webkit-transform: rotate(90deg); -moz-transform: rotate(90deg); -o-transform: rotate(90deg); -ms-transform: rotate(90deg); transform: rotate(90deg); Otherwise, you can do this by setting a data attribute in your HTML, then using Javascript to add the necessary styling: Sample ...

4. math - How do I rotate an image? - Stack Overflow

   stackoverflow.com/questions/695080

   To rotate an image, you create 3 points: A----B | | C and rotate that around A. To get the new rotated image you do this: rotate ABC around A in 2D, so this is a single euler rotation; traverse in the rotated state from A to B. For every pixel you traverse also from left to right over the horizontal line in the original image.

   You can use a CSS animation to easily, continuously, and performantly rotate your image. In order to keep the animation from playing right away, you can set the animation-play-state CSS property to paused. When you want to make the animation play — to make the fan rotate — you can either unset animation-play-state or set it to running.

6. Matplotlib rotate image file by X degrees - Stack Overflow

   stackoverflow.com/questions/34801342

   11. Because I wanted to be able to rotate tensors I came up with the following piece of code, which rotates a [height, width, depth] tensor by a given angle: def rotate_image_tensor(image, angle, mode='black'): """. Rotates a 3D tensor (HWD), which represents an image by given radian angle. New image has the same size as the input image.

    Quickest 2D context image rotation method. A general purpose image rotation, position, and scale. // no need to use save and restore between calls as it sets the transform rather // than multiply it like ctx.rotate ctx.translate ctx.scale and ctx.transform // Also combining the scale and origin into the one call makes it quicker // x,y position of image center // scale scale of image ...

11. Image scaling and rotating in C/C++ - Stack Overflow

    stackoverflow.com/questions/299267

    I would like to be able to scale this image by an arbitrary factor and get a new image. So, if I scale the image by a factor of 0.68, I should get a new image of size 0.68*1024 x 0.68*2048. some pixels will be collapsed onto each other. And, if I scale by a factor of say 3.15, I would get a larger image with pixels being duplicated.
