You could attach the image (as a pixmap) to a label then add that to your layout… … QPixmap image(“blah.jpg”); QLabel *imageLabel = new QLabel(); imageLabel->setPixmap(image); mainLayout.addWidget(imageLabel); … Apologies, this is using Jambi (Qt for Java) so the syntax is different, but the theory is the same.
I suspect the path is not correct. As mentioned by user7412219 ubuntu and windows deal with path differently. Try to put the image in the same folder as your Notebook and use:  On windows the desktop should be at: C:\Users\jzhang\Desktop
First, you have to get an API key. If a maximum of 50 uploads per hour is sufficient, and you don’t want to register an account, get an anonymous API key. Instead of binding a left-click event handler, which may interfere with a page, I suggest to add a contentmenu entry using the chrome.contextMenus API. … Read more
This is not supposed to be a solution, but rather an explanation and a possible, although ugly workaround. From time to time there are reports to the gnuplot mailinglists about this issue, but it seems to be related to the viewers. It has to do with the way gnuplot creates the surfaces plots. These are … Read more
Your row/col sizes are reversed. Since MATLAB arrays are column-major, and raster images are usually stored row-major, you need to read the image as a [col row] matrix, then transpose it. row=576; col=768; fin=fopen(‘m-001-1.raw’,’r’); I=fread(fin, [col row],’uint8=>uint8′); Z=I’; k=imshow(Z) The image replication is happening because you’re short 768-576 = 192 pixels per line, so each … Read more
Since no one has posted a complete OpenCV solution, here’s a simple approach Obtain binary image. Load the image, convert to grayscale, and Otsu’s threshold Remove horizontal lines. We create a horizontal shaped kernel with cv2.getStructuringElement() then find contours and remove the lines with cv2.drawContours() Remove vertical lines. We do the same operation but with … Read more
This function implements the reverse blend described by Mark Ransom, for an additional small but visible improvement: reverseBlend[img_Image, alpha_Image, bgcolor_] := With[ {c = ImageData[img], a = ImageData[alpha] + 0.0001, (* this is to minimize ComplexInfinitys and considerably improve performance *) bc = bgcolor}, ImageClip@ Image[Quiet[(c – bc (1 – a))/a, {Power::infy, Infinity::indet}] /. {ComplexInfinity … Read more
There is an api in Express. res.sendFile app.get(‘/report/:chart_id/:user_id’, function (req, res) { // res.sendFile(filepath); }); http://expressjs.com/en/api.html#res.sendFile
JPEG steganography If you want to save your image to jpeg, you have to follow the jpeg encoding process. Unfortunately, papers most I’ve read say don’t do it justice. The complete process is the following (wiki summary of a 182-page specifications book): RGB to YCbCr conversion (optional), subsampling of the chroma channels (optional), 8×8 block … Read more
You can easily load multiple images with same type as follows: function Seq = loadImages(imgPath, imgType) %imgPath=”path/to/images/folder/”; %imgType=”*.png”; % change based on image type images = dir([imgPath imgType]); N = length(images); % check images if( ~exist(imgPath, ‘dir’) || N<1 ) display(‘Directory not found or no matching images found.’); end % preallocate cell Seq{N,1} = [] … Read more
