SVG picture is returning black image in flutter inspite of giving a color image from assests

But finally, I solved it with the help of this software, svgcleaner. Download the application into your OS, from here After installation, import your SVG. Click run. Success! Here you … Read more

Get coordinates of local maxima in 2D array above certain value

import numpy as np import scipy import scipy.ndimage as ndimage import scipy.ndimage.filters as filters import matplotlib.pyplot as plt fname=”/tmp/slice0000.png” neighborhood_size = 5 threshold = 1500 data = scipy.misc.imread(fname) data_max = filters.maximum_filter(data, neighborhood_size) maxima = (data == data_max) data_min = filters.minimum_filter(data, neighborhood_size) diff = ((data_max – data_min) > threshold) maxima[diff == 0] = 0 labeled, num_objects … Read more

“Parameter not valid” exception loading System.Drawing.Image

I had the same problem and apparently is solved now, despite this and some other gdi+ exceptions are very misleading, I found that actually the problem was that the parameter being sent to a Bitmap constructor was not valid. I have this code: using (System.IO.FileStream fs = new System.IO.FileStream(inputImage, System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite)) { try { using … Read more

Stretch image to fit full container width bootstrap

In bootstrap 4.1, the w-100 class is required along with img-fluid for images smaller than the page to be stretched: <div class=”container”> <div class=”row”> <img class=”img-fluid w-100″ src=”#” alt=”” /> </div> </div> see closed issue: https://github.com/twbs/bootstrap/issues/20830 (As of 2018-04-20, the documentation is wrong: https://getbootstrap.com/docs/4.1/content/images/ says that img-fluid applies max-width: 100%; height: auto;” but img-fluid does … Read more

Similar image search by pHash distance in Elasticsearch

I have simulated and implemented a possible solution, which avoids all expensive “fuzzy” queries. Instead at index-time you take N random samples of M bits out of those 64 bits. I guess this is an example of Locality-sensitive hashing. So for each document (and when querying) sample numberx is always taken from same bit positions … Read more

Got an error Invalid src prop (‘here is a link’) on `next/image`, hostname “localhost” is not configured under images in your `next.config.js`

const src = `${API}/user/photo/${blog.postedBy.username}`; <Image loader={() => src} src={src} width={500} height={500}/> Here, loader is a function that generates the URLs for your image. It appends a root domain to your provided src, and generates multiple URLs to request the image at different sizes. These multiple URLs are used in the automatic srcset generation, so that … Read more
