I'm trying to flip a BMP image in C. I ran into a problem where when I try to read the BMP header everything is alright and the values are correct, but when I try to read the DIB header I get all of the values right except for the image size (raw bitmap data). I get a zero, which is really weird considering I got the file size in the BMP header. I tried debugging the code and looking up the problem online but that didn't help much.

This is my code:

Question: How can I know that an image variable has successfully loaded an image from an image url?

The relevant javascript code I have been using is below (I am coding a Chrome extension). I want to grab a random image from an array of images, so I can use (inject) the random image on a webpage. But since I am grabbing the images off some websites that have tons of free images, I want to make sure the random image is not blocked by the free images website for whatever reason (and if it is blocked, then I will try another random image from maybe another site). I need to know that img.src contains an actual image or not. I am new to javascript, reading a book on it I just got yesterday-- do I need the semicolons or should I just ditch using semicolons? (I come from a background coding in C/C++)

Right now it overwrite same cell in Logs I need it to write to next cell and not overwrite the same cell. https://freeimage.host/I/5GIOjs I want to Search for D3=Lumee in the Sheet called Logs in colum A u see all the names. Want it co copy J12 to the specific Name https://freeimage.host/i/5GTLJI

I try to add metadata to an existing JPEG file and saving the image in another file. I'm using Delphi 11 and FreeImage (Delphi wrapper). The image is produced identical to the existing image, without the added metadata tag. No error at all.

Here is a simple stand alone procedure to reproduce the issue:

I have a 16-bit tiff image with no color profile (camera profile embedded) and I am trying to read its RGB values in OpenCV. However, comparing the output values to the values given when the image is opened by GIMP for example gives totally different values (GIMP being opened with keeping the image's profile option; no profile conversion). I have tried also another image studio software like CaptureOne and the result accords with GIMP differs from OpenCV output.

Not sure if reading and opening the image in OpenCV is wrong somehow, in spite of using IMREAD_UNCHANGED flag.

I have as well tried to read the image using FreeImage library but still the same result.

Here is a snippet of the code reading pixels' values in OpenCV

When loading the image with the nuget package, (FreeImage 3.18.0.0) it does not unload memory even if '''dib.SetNull()''' was set.

I'm trying to show an image in a "lightbox" style so that it will fill the available area on screen, in this case 90% of the width of the page and 70% of the height.

Using object-fit: contain; seems to be the de facto way to do that but it's not quite working with border-radius. Is it possible to use object-fit on an and still have the border radius applied as intended?

You'll need to resize your browser window to see what happens when you run the below snippet. I've got the same code running in JSFiddle, as per the below video.

I have to do a task for university in C. The program creates images in PGM format.The program compiles successfully, however, I can't run the program correctly. At the beginning of the main function the if operator needs 2 argc, but every time I try to run the program I just have one argc and I get the result

"Error: missing or bad parameters, usage a3 [imagefile]"

The code is:

Good day to everyone. I am learning javascript. I know these codes I have written are not the best of codes. I am more interested in getting my codes to work at this stage. So, I have three images I setup in HTML and styled with css.

I simply want the images to move to certain positions 3 seconds after page load and slide back to their initial positions 3 seconds interval. The problem now is that I will like to make this repeat every 3 seconds as long as the user is on the page. Here is what I have written:

Currently, the images actually slide how I want them to but I don't know how to make this happen over and over again.
