gif

问题 I was just wondering, if there's some way how to automatically save the content of the cell (including the cell output) to a PNG/PDF/JPG/GIF. I'd be happy with any of the alternatives. For documentation purposes I'd like to save the state of a VBox/Hbox containing multiple iPython Widgets. There are many possible combinations of the widgets settings, I can iterate over these settings with my code, but I'd like the corresponding visual setting of the widgets to any of the possible above

问题 I have a list of .png (PIL) images I want to string together into an animated gif To do this, I am currently using the imageio library However, I cannot find a way to do this to produce good quality gifs As far as I know, there are two types of settings I can change. The imageio.imread() settings for reading .pngs, and the imageio.mimwrite() settings for writing gifs. According to imageio.help() , imageio.imread() has one read paramter only for PNG-PIL , ignoregamma which takes a boolean.

问题 I hope you guys can help me with this one. I'm not sure if it is a bug in Java or if I'm doing something wrong, but I'll go with the latter. I want to turn a BufferedImage into a GIF image. I then wish to keep the GIF in the memory in the form of a byte array. (I do not want to save the file to disk) The program should capture a screen segment (just to create a quick image) and turn it into a GIF byte array using ImageIO ImageWriter and ByteArrayOutputStream. The code below will show you the

问题 I just spent an infuriating day trying to make a gif out of a series of jpg files in R. I installed ImageMagick to run the following code: system("convert -delay 40 *.png example_4.gif") but I get the following error message: Warning message: running command 'convert -delay 40 *.png example_4.gif' had status 4 which looks like a path error. Now I've looked for convert in the Imagemagick download and can't see it anywhere. Does anyone know where it is? Alternately, is there another easier

问题 I'm using the below to grab an animated gif off the web. However, upon saving this to disk, I lose the frames in the gif, and it no longer animates. Not sure whether the problem is in the below method, or whether it's when I'm saving it, but any feedback on why the below wouldn't work appreciated. The method is working - just not creating a proper animated gif file. public Image getImage(String url) { HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url); HttpWebResponse
