Thread: new idea....need help!

hey there...this is my first attempt at this kinda project...just came to my head...i need to project abt a 100 jpeg images over a period of time on a projector...they need to be in a random order and they need to appear one after the other very very quickly..

so the first time i kick off the program it selects say any 50 out of 100 images and projects them on the screen one after the other in a loop, say till i press stop...

second time it does the same thing but with a diff set of images...and so on...

writing the program part i can do...but how do i get in to run...would it treat individual images in a specified folder as seperate files?...so can i use fopen to display?...how do i ensure it comes on the screen (full screen)?...any guidance on the logistics would be appreciated....cheers!

I don't know which environment you are using. But I could imagine you should do something like: compile and link and then type the programs name. Then it should run.

Depends on your own ideas. You can do it whatever you want. Since it are JPEGs, they are seperate files.

>so can i use fopen to display?

No, fopen can't be used to display a JPEG file. It can only be used to open a file. Then you need to decode the JPEG file and display the picture.

you could convert all the images to bmps and use allegro to display them.

That's what I would do if I didn't have much time.

somebody mentioned fopen is out of question...so allego is the way to go...could any1 tell me where i could read up on allego with regards to projecting images on a screen...i am pretty new to this stuff and haven't quite come across that term...

would this solve the problem of picking up images from a specified folder and then displaying them full screen?...any help would be greatly appreciated...cheers!

It's Allegro instead of Allego. You can find info on it by using a search machine. But anyway:
