Image displaying

I need to learn a way, using a bitmap, to display an array of tiles (for a map) as colored squares. What is the easiest way this can be done and how can it be done?

Well your going to need to use a graphics libary, I myself am a big fan of allegro.

homeyg · 01-03-2005, 03:16 PM

Is there anything I need to install to use a graphics library?

prog-bman · 01-03-2005, 03:19 PM

Yes you are going to need to install the headers and lib files for a library. This depends on your compiler.

homeyg · 01-03-2005, 03:28 PM

My compiler is Dev-C++.

Check to see if your version of Dev-C++ has an update feature. It might be under help or tools. I know with the current version it not only lists updates put development packs as well. One of them should be Allegro.

Allegro For Dev:

Tutorial:

Good Resource
http://www.allegro.cc

Alright, I downloaded and installed the Allegro Dev-pack. Should that be it before I can use it?

prog-bman · 01-03-2005, 04:48 PM

Everything should work fine start a new project. It will in multimedia

homeyg · 01-03-2005, 04:53 PM

Thanks.

I'm getting some error messages when I try to compile the program in the first tutorial: It's not telling me that the file <allegro.h> is undefined but it is telling me that there are undefined references to all of the functions in the tutorial. They are all classified as linker errors.

MadCow257 · 01-03-2005, 05:10 PM

A random guess is that you aren't including all of the libs in project settings, the specific errors would help

homeyg · 01-03-2005, 05:12 PM

Actually, scratch that. I did what prog-bman said about the projects and now there is only one error: 'no new line at end of file'. What is that supposed to mean?

Hello,

This seems to be a continous error. View this previous thread: No newline at end of file

Kind of a silly error and easily fixed. Make sure each of your code files (.c/.cpp and .h) has a blank line at the bottom.
