I need to be able to save out extremely large images, and FreeImage just isn't doing it :/ It saves the images up to a certain size, but won't go any higher (gives a "Failed save" error) Any ideas?

What do you mean "FreeImage" isn't doing it?


Tyler(Posted 2005) [#3]
The free image library that saves out JPGs, TGAs, and PNGs


Grey Alien(Posted 2005) [#4]
I must be dumb, but I still don't know what you are talking about, sorry.


Tyler(Posted 2005) [#5]
S'alright, I need to figure out how to get a 22,000+ wide by 16,000+ tall image to save without an error, lol.

Maybe add some ram to your computer? You are talking about a requirement of 1.5 Gigabytes for that resolution.


Tyler(Posted 2005) [#7]
I have 2 GB :/


Grey Alien(Posted 2005) [#8]
that's pretty big (said the nun to the bishop)

Given FreeImage will be trying to allocate it's own copy you're going to need double that. Also, seeing as compression would seem to be a completely pointless waste of time (as in why introduce huge delays when you obviously have the resources to manage uncompressed sizes) you would be better off IMHO to just save the raw image:

ok, I think I got it, thank you! Since the images are such high resolution, I can half it and it works beautifully. Thank you for the link too!

Tyler, I don't get your sig. When I click it, I just go to the start page for a forum with no mention of the alphabet that I can see...

P.S. is a sequence of letters with Q and R removed, are you a programmer or what? ;-)


Russell(Posted 2005) [#13]
Sorry, not following you. Is the answer in the link or in the sentence?

Russell


Russell(Posted 2005) [#14]
Ok, if you mean P * * S (q and r missing), then the sig is still wrong.

P.S. This is what the alphabet would look like if Q and R were eliminated


Actually, the alphabet would look like abcdefghijklmnopstuvwxyz. But I'm splitting hairs, I know ;)

See, that was more of a programmerly response :D BTW, if you're having trouble with images being too big for blitz to handle ... use the FreeImage library by Mr. Snarty! Thank you again!
