lordfrikk Posted March 25, 2008 Share Posted March 25, 2008 PHP (GD2, that is) can't handle BMP files, unfortunately. You can write your own BMP handling function, though (lol).

darkywarkey Posted May 25, 2009 Share Posted May 25, 2009 Can someone lead me to a good resource to learn how to write a conversion program? I want to properly convert BMP's to JPG's when they're uploaded. BMP's are almost always much larger files, and it would be far more efficient to use a JPG version. Any experts out there that can help?? ??? Link to comment https://forums.phpfreaks.com/topic/97795-how-to-convert-bmp-to-jpg/#findComment-841633 Share on other sites More sharing options...
Axeia Posted May 25, 2009 Share Posted May 25, 2009 I'd disallow uploading of bmps to in the first place, don't think anyone would actually benefit from uploading a many megabytes big bmp. imagick seems to support nearly every image format btw.

Kieran Menor Posted May 25, 2009 Share Posted May 25, 2009 Disallowing BMPs altogether seems like a better solution. BMP mostly only seen when saving images from MS Paint without changing the file type in Windows versions older than Vista. Just because of this, implementing BMP support seems like an awful waste of time to me. Besides, as you just said, BMPs are larger and as such, users will be annoyed by the longer upload times. It really isn't hard to save an image as a PNG instead of BMP, but if you're concerned, you could add a small guide on how to choose a different file type in MS Paint. Not exactly what you asked for, but an opinion nonetheless.

darkywarkey Posted May 26, 2009 Share Posted May 26, 2009 I'm on a shared hosting environment, as such not sure how to set up imagick on it. tried before, didn't get much customer help - but I think you guys are right. I may just disallow it, I doubt anyone will be using it anyways. And I dont wanna kill the bandwidth of my site from 2megabyte image uploads for the 2 people that will use it. Thanks..
