gif

问题 I am trying to show a gif file in google's colab.research. I was able to save the file in the directory with the following path name /content/BrowniamMotion.gif but I don't know how to show this GIF in my notebook to present. The code to generate the GIF so far, in case someone can manipulate it not to save the GIF but rather to animate it directly into the google colab file was, # Other Brownian Motion from math import * import numpy as np import matplotlib.pyplot as plt from mpl_toolkits

问题 I am working on a service that can do conversions from gif to mp4 files (with ffmpeg ). My problem is some of the gifs have visible transparent areas which end up as white color when I convert them to mp4 video. To avoid that problem I am trying detect if a gif has visible transparent areas so I will avoid converting them to mp4. I tried to use getImageAlphaChannel() function from imagick. if ($imagick->getImageAlphaChannel()) { echo 'transparent image'; } else { echo 'not transparent image';

问题 I'm doing image tracking using AR Kit, once image is detected i'm playing GIF with GIFUhttps://github.com/kaishin/Gifu library. This is successful with below code. In VC i added GIFImageView as below: var imageView = GIFImageView(frame: CGRect(x: 0, y: 0, width: 600, height: 600)) And in ARSceneView delegate didAdd node method is below: func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) { DispatchQueue.main.async { self.instructionLabel.isHidden = true }

问题 I wanted to apply Django's Signals to the following model: class Video(models.Model): created = models.DateTimeField(auto_now_add=True) text = models.CharField(max_length=100, blank=True) image = models.ImageField(upload_to='Images/',blank=True) video = models.FileField(upload_to='Videos/',blank=True) gif = models.FileField(upload_to = 'Videos/', blank = True) class Meta: ordering = ('created', ) The reason why I use signals: Whenever a Video object gets created, we get notified and then we

问题 You know that GIF files support animation, but a GIF image not necesarily must have an animation on it. Is there a way to check if a GIF image has an animation using php or java? Thanks. 回答1: Here is a little PHP script that should be able to determine if an image is an animated gif or not. I have tested it and it works for me. <?php $img="your_image"; $file = file_get_contents($img); $animated=preg_match('#(\x00\x21\xF9\x04.{4}\x00\x2C.*){2,}#s', $file); if ($animated==1){ echo "This image

问题 Through ActiveX Control Microsoft Web-browser , we can trigger the navigation of a GIF file within a web browser box in Excel. I do this by defining a button and assigning a macro to it which gives the local address (or link) of that GIF image for the navigation to be done. The problem with this is, in order to use such an excel file for presentation, you have to carry the GIF file too on any computer its going to be launched. While when we insert an image into an Excel file, it will be
