I know it's possible... but how is it done?


What I'm trying to do is find an unused file name and the file names have numbers at the end, so i was gonna loop through numbers until I found a file name that didn't exist and could be used.

Example: "Pic7.jpg"

char buf[256];
sprintf(buf, "Pic%d.jpg", num);

Huh... when I do it like that, I get a "buffer overrun" debug message when I escape the program.


It did work, though. So, I'm happy about that.

Awesome, that fixed it much better. Thanks a ton, Zuka!

Now my problem is with the saved file.

Here's my screenshot code: (Saves a screenshot)


The resolution (SW and SH) is 1280x1024. The image gets saved as a 2048x1024 image... which is understandable considering it's in a power of 2, but how do I make it save the image in the correct dimensions?

The only way i could think is to make a offscreen bitmap the same size as the image you need then copy the bitmap you want to save to that one and save that bitmap,and get a image of that bitmap if you need it.

#include <string.h>

char string1 = "pic";
int num = 7;

strcat(string1, dbStr(num));
strcat(string1, ".jpg");

dbGetImage(1,0,0,SW,SH, 1);

the extra flag at the end will tell the GDK to not resize the image for texturing when it is loaded.
