How would I get images to stay in the imagecreatetruecolor, so I don't have to see the black?

Please provide a less obscure description of your problem...

How would I have the width and height set to where it fits the image color, using imagecreatetruecolor, the background is black, and no matter how much I try when using imagecopyresampled, it will show the background imagecreatetruecolor

imagecreatetruecolor() returns an image identifier representing a black image of the specified size.

in order to change the background colour you can use the following script.

PHP Code:


			
$bg = imagecolorallocate($im, 233, 14, 91);

Place right after the imagecreatetruecolor()

I know that, but you don't get what Im saying.. I mean Im getting the image from a database. And I hate black backgrounds showing up, ya know, so yeah.

I'm guessing your trying to do transparency images?

You dont need to be rude about it i am sorry if you are not very clear on what exactly you want

How about giving everyone a visual example (starting images [yes, from the database], resulting images [with black backgrounds] and the appropriate code you're using [or all of it])?

Sorry Rendair, hang on, lemme try to make it better..

Say that the black was the imagecreatetruecolor width and height, when cropping images, it does this to me, when just resizing it, its fix, how would I get this? Say, to a certain point of which the image width ends, I dont want imagecreatetruecolor width's black, I would it to be stopped, how would I do this?

Or shall I delete this thread, and figure it out myself? I don't know what else to say. :/

Well, I'd suggest you calculate the thumbnail dimensions BEFORE creating the virtual image to store the thumb into. Then, you wouldn't have problems with imagecopyresampled. If the image has some transparent pixels around it, run a function on the image to see where is the image ending (imagecolorat).

I have done that. I took the width and height and list() them and then put them in the database like so 000x000, then I went and explode() the x and made $foo[0] and $foo[1] thus gave me the width and height.

Mind posting your code :D & db table example
