imgmap | Javascript based imagemap editor | Canvas library

I am trying to screenshot a specific portion of a sheet & export the file with a certain name. I've figured out how to properly export the file the way I'd like it to be but I'm having trouble with the naming of said file. The file name is in a cell of the active workbook so I tried using the LEFT function to extract it from the cell. Below is my code:

I need to show the corresponding image according to the checkbox controls selection, it works at the moment of selecting a box and showing its respective content, but if I remove the selection from some of them it doesn't work anymore.

I have Xamarin Forms Cross Platform project with a ListView whose ViewCell contains a StackLayout. I hide and show the StackLayout when the user clicks on an image. There is a known issue with the ViewCell not resizing correctly on iOS and solution I found was to use ForceUpdateSize method on the ViewCell in order to for the app on iOS to resize the cell. This is working from the aspect of resizing the ViewCell - however after calling the method, I loose the three buttons at the bottom of ViewCell. The buttons are in a grid and all the code, xaml and screen shots are below. Any help with resolving this would be greatly appreciated.

I am using C on MS-DOS, specifically Turbo C, and I encountered something strange with my numbers being read here. I have a function called writeBitmap that in essence takes a struct with a path, x and y size, and then offset for a sprite sheet, as well as an array that defines each image using this.

The problem I am having is when I reiterate over the cached image data I get from a file, the output from the array always gets read as if it were an integer if it starts with FF. What I mean by this, is if there is an FF in my array, when I use an if statement to test to see if it's there it acts like it's reading an integer containing the FF, and then the next character concatenated. This means that I can't detect an FF (which is a transparency byte by the way) because whenever it's present, it reads it and then the next byte at the same time, even when casted to a char.

Here is my code, I am omitting some stuff, but up top I have this information:

In WPF , i create button on canvas. like this.

I want to display an image (It can be of any size) only in a table of 1280 x 800 Resolution it will not display on other screens.

Now I'm using an element inside the body, and if the image is small, it doesn't fill the screen and if the image is big, it display it out off the screen.

So the html is this:

I need to load image for a marker from the URL. Until image gets loaded from the URL I need to show the default image.And my map page will be like below:

Marker background image is white and icon(eg: bag and car) in it will come from network URL.

I have achieved relevant output by creating a marker using BitmapDescriptorFactory.fromBitmap.

I am trying to do a function that displays different things when called by different ids in the tag area.

I've read the answers to similar request, but I couldn't figure out my mistakes.
