backend

问题 I'm working in Spyder with matplotlib.pyplot and want to save numpy array to images. The documentation of imsave() says, that the format to which I can save depends on the backend. So what exactly is the backend? I seem to be able to save .tiff images, but f.e. I want them to be saved as 8-bit tiffs instead of RGB-Tiffs. Any Idea where I can change that? Greets Joni 回答1: If you are trying to save an array as a tiff (with no axis markers ect) from mat, you might be better off using PIL. (this

问题 I'd like to implement something like the powerpoint image below. A gradient that goes between three values. It starts at A (-1) , the mid point is B (0) , and the end is C (1) .

But I'm stumped (despite googling) on how to get from one colour to another - ideally in the RGB colour space. I'd like to be able to

问题 I was trying to recreate the cocoapi demo script by copy pasting it into my own local script instead of running it on a Jupyter notebook. Everything works fine and there's definitely an image read and can be displayed because I've tested it with openCV's imshow() function (and the image pops up). However, when I tried opening the image with plt.imshow() and plt.show(), the image would not appear. I went online to search for solution at they suggested its a backend issue? However, when I ran

问题 I've never used Google App Engine backends and I'm very confused by lack of samples and detailed documentation. Let's say I have a voting app. I want to collect votes in regular stateless GAE servlet and then pass the data to backend instance that is resident and it processes my data. How can I pass data from regular servlet to backend servlet ? How do I assign what servlet class is normal servlet and what servlet should be handled only in backend instance?

问题 Hi first of all i have to confess i really don't understand how the whole Passbook topic really works. So here's my situation: I have a backend system which creates .pkpass files stores them and creates an URL. When i open this URL in my browser it directly starts to download the pass file.

Webservices can send your pass data in base64(NSString) format and you decode

问题 In the backend I want to display some configurations of the plugin the editor has selected. Like in powermail or news plugin. How can this be achieved? 回答1: You'd apply the same logic as for a custom preview of any custom element: You can use PageTS to register a custom Fluid template: // Register preview for a custom content element mod.web_layout.tt_content.preview.my_content_element = EXT:my_ext/Resources/Private/Templates/Preview/MyContentElement.html // Register preview for a plugin mod
