Re^3: Centering Text with GD::Image

Of far greater concern, is posting code like:
new GD::Image->stringFT(...)

Hi Ken,

Thanks for your wise words and useful link. I don't write this form in code that I formulate from scratch...but, no doubt it came from the GD Documentation. I think, but I'm not sure, that this code actually came from an example somewhere on the web rather than directly from the documentation.

Your memory serves you well!
I did post Adding a watermark to an image with GD::Image some time ago and the code I posted was the same code shared above. The indirect syntax was in the original part and you did mention it at the time...I had no idea what the term meant then and didn't get around to looking at it further as getting the watermark colours (the subject of the question) showing correctly was the priority.

I wouldn't use indirect syntax in code I produce from scratch. I don't know why...I just wouldn't do it that way. I will be sure to look more at the links you shared to find out why I shouldn't do it that way...

Fortunately, the code was helpful to djlerman. Hopefully, he will also look into your links...

G'day Bod, "Thanks for your wise words and useful link." You're very welcome. When you get around to reading the documentation to which I linked, you'll see the very good reasons for avoiding indirect syntax. You will still encounter `new Some::Module` on CPAN and elsewhere; I just write `Some::Module::->new()` and move on. Code like `new Some::Module->method()` can be difficult to understand and, in my opinion, should never appear in modern Perl code. As the doco explains, Perl itself can have trouble parsing indirect syntax code. [By the way, you might want to take a peek at my response to pryrt's reply.] — Ken	[reply] [d/l] [select]
