Image Map

210 Recognized Expert New Member
I have a US map image in my page. My application is supposed to highlight the states that an individual have visited. For example if i have visited state MO, IL , KS then in the image the states MO, IL and KS needs to be highlighted with a color. I am trying to use image maps but i am being unsuccessful to highlight it even though i have the coordinates.

I have been researching on this and have not found any help so far. Is there a different approach to this ? Please advice

I'm not sure how you would achieve this.

You could consider having a regular, unhighlighted map showing by default...and a "master image" (something like described in this article about Sprites)...and if the user has visited the State then grab the highlighted State image from the "master image" and move it over top of the default map.

Or you could consider creating the image server side using the graphics tools that .NET provides (I'm not great with this though and I'm not sure how you would highlight a "State")

I figured this out. I created the image using graphics tool and then highlighted the state accordingly. Learned something new.

I'm implementing some image processing algorithms in C++. I created a class called 'image' (see declaration below), that will take care of the memory allocations and some basic (mathematical) stuff. The class will behave like a std::vector (copy constructor and assignment create a deep copy), but with 2D indexing. Now I also need a 'view' class that will behave like a reference to an 'image' (can only be constructed from an existing...

Hi, I'm trying to create a grayscale image class that reads and writes grayscale Targa format. This works well with smaller images, but corrupts larger images and creates a "Segmentation fault (core dumped)" error. I am at a loss as to why this works only part of the time. I hope it's proper etiquette to post the code below (3 files). Can someone please show me what's wrong with the following code? I
