 |
|
Greetings!
I am trying to find the height and width of an image with this little program,
| Code: | import std.stdio;
import std.string;
import dfl.all;
void main() {
auto picture = new PictureBox;
picture.image = new Picture("psipmain.JPG");
writefln("width = " ~ std.string.toString(picture.image.width));
writefln("height = " ~ std.string.toString(picture.image.height));
//picture.dispose();
} |
I see the dispose() function there and I am wondering how is it use? I am opening thousands of pictures and all I am doing is just getting their size and then creating an HTML report on the whole directory structure. When do I use dispose to clean the memory? Or is this even what this function is for?
thanks,
jose |

| The dispose method releases the internal image resources. You can call it when you're done with a Picture instance. |

| If I do use it, for example, in the code above, if I uncomment it, the height and width never get displayed. So, perhaps I should use it at the beginning. |
