I would like to convert a powerpoint presentation into a series of images. One per slide specifically so they can be uploaded as an image gallery to a blog. Does anyone know of any libraries that can convert a .ppt into images. Any language is fine as long as it can run on a *nix server, so no C# or .Net dependent libraries.
Even if one existed, and I would guess one does, it can't address animations in a meaningful way. I see more and more ppt presentations making good use of animations to get their points across. Many of these animations will overlap one another. How could such a slide be turned into a single image? How would you prioritize which animated image segments should overlap the others? You may want to keep an eye on this thread: Converting ppt to png using Apache poi
This might get you a solution via php How to work with powerpoint in php?
This might work with python: https://stackoverflow.com/q/4995877/657003

So, I have searched enough, got one or two ways but failed to get an exact solution to my problem. I have an image of a body like this:
Now when tapping on different body parts, those bodyparts will be highlighted like below image:
This is a back body portion image for reference.
Now I have small images like:
To highlight the body parts. Can anyone please suggest me a way how I can achieve this. Just guide me with a way that will be enough. Thanks in advance.
It should be fairly easy, let's say the full human body is 400x800, and you got like 5 body parts, then create 5x 400x800 images with each body parts in the exact location, stack each on top of each other, the invisible layer will match and display the whole body normally.
To highlight, simply switch the image in the corresponding imageView. To handle user touch, you should have a tap gesture to figure the location, then change the correct image layer.

Im trying to create a view that glows very intensely and in the dark even, kind of like what this app here has accomplished (https://itunes.apple.com/us/app/mood-colors/id545822095?mt=8). I tried adding a sprite kit particle to the view and started messing with that but it really didn't take me anywhere and I couldn't get the results I wanted. Any help would be greatly appreciated. Also, incase you want to know, I am working with Swift 4 on a regular single view app and I am a bit of a beginner.
Thanks in advance.
This is only images showed with bright colors. If the images have very vibrant colors this could be achieved. It also looks like there are several shapes that the user can set a color to themself. But please bear in mind that phones using OLED (as iPhone X) can burn the image in and destroy the screen if something is shown very statically.
If you like to draw shapes (like a star) there is a solution That can be found here
Happy coding!

I'm going to be more specific about the situation:
I've captured a screenshot from the game DotA. The information I want to get is what objects eg. heroes (also its name, hp, ...), creeps (also which side), towers, etc. is visible in the image and where they are. A problem come from the fact that in DotA 2 many of these object can be viewed from many perspective, so let's reduce the problem and assume that every object have only one orientation. How might this problem be solved quickly enough, that it can recognise all objects in real time at about 30fps? Any help or suggestions is welcome.
I think that you have the good flags: CNN for image segmentation. So my point is that for so many different objects from different points of view and scale (because I guess that you can zoom in/out on your heroes/objects), the easiest way (but the heaviest in term of computation) is to build one CNN for each type of object.
But images would help a lot to get a better understanding of the problem.

I'm stuck on a problem and needed some help or guide for a possible solution.
Basically in my application there will be a map with several zones.
The user can select any of these areas, at that time this area is filled with a color.
Imagine a map like this one, so i need to be able to change the color of only one country.
Something like what happens in the books of paintings (https://itunes.apple.com/pt/app/colorfly-best-coloring-book/id1020187921?mt=8), or Paint Bucket command in the Photoshop .
Any idea how to get something like this on iOS ?
Thanks in advance
The paint bucket technique you're looking for is a set of graphics algorithms usually called "flood fill". There are different approaches to the implementation depending on the circumstances and performance needs. (There is more at that wikipedia link.)
I have no experience with it, but here is a library from GitHub that purports to implement this for iOS given a UIImage object: https://github.com/Chintan-Dave/UIImageScanlineFloodfill
Re: your question about doing this without user touch: yes, you'll want to keep a map of countries to (x,y) points so you can re-flood countries when required. That said, the intricacies of the county borders might make an algorithmic fill inexact without more careful normalization of the original source. If your overall map only contains a small set of possible states, there are other ways of achieving this goal, like keeping a complete set of possible images (created in ie Photoshop) and switching them out, or keeping a set of per-country "overlay" images that you swap in as needed. (But if the flood fill is accurate on that source image, and performant for your needs, then great.)

I want to dynamically create realistic clouds including their movement and multiplication (density). I found this link which seem to explain more than I can understand. I cannot find a way to replicate the clouds and there is practically no other tutorial online. Does anyone know how can I achieve this result? Thank you in advance!
use scene kit you can make a dynamic particle effect:
https://developer.apple.com/library/prerelease/ios/samplecode/SceneKitVehicle/Introduction/Intro.html
in this example you can find, after the vehicles code, the smoke animation. You can gat all the stuff you need from there, like smoke.scnp, smoke.png.
You need to change some row of code like the smoke color, the light color and the camera position.
But with that i guess you can have one of the best result possible, as real time cloud simulation, in iOS.
(other solution would be using openGL but trust me this is a ton easier)
maybe this guide can also be useful to understand the basis (you just need them to achieve your clouds) :
