[PHP] Image Generation
Hi, I need to generate an online proof for vinyl lettering. Customers specify the text, font, colour, maximum frame size (mm) (ie the width and height it must fit into), and whether or not they want to keep aspect ratio (ie not distort the lettering). I want to represent all this on a single image. So it would display a border with their width and height on, and inside this would be the text in the appropriate colour and font – if they decide to keep aspect ratio the text would not be distorted. If they do not, it would be. The image would always be 300px wide by 150px high (these would need to be constants that I could change from time to time). I’ve got a very basic proof working using a GD wrapper, but I don’t think GD is powerful enough to do it all, nor do I recon my programming skills are up for it. Has anybody got any advice on how to tackle this, even if it is just bits of the problem?? Thanks, Alex Chamberlain No virus found in this outgoing message.

Re: [PHP] Image Generation
I don't think GD has a built-in function to scale an image the way you are asking, and to do it on a pixel by pixel basis from within a function is going to be a very time consuming and memory costly process. Have you thought about using ImageMagik to do this? I know that you can exec() out to this from within Windows and Linux, and ImageMagik is free to use (as far as I'm aware) so it could be just what you need.

GD can do all this, although I hear said that ImageMagick does more and has
somewhat
better output.
you'll only be able to offer fonts that you have installed on the server, also
image generation works in pixels so you'll have to come up with a way to
'convert'
millimeters to a pixel value for display purposes.
I offer you a class that you might be able to use, at least for inspiration ...
the pertinent functions used are ImageColorAllocate(), ImageTTFBBox() and
ImageTTFText()
?

Just to clarify some points, there is no need for this to be of
print quality - it is an online representation of the vinyl they will
recieve in the post.
Also, the main problem I've got with GD, is generating text that is
stretched? Do I need to generate a text image then stretch this using
normal resize functions??

that has no direct bearing on the image file itself.
Alex will have to figure out the bounding box ratios of the

If Alex requires pixel perfect representation of print output in a

then he
is going to have to resort to some kind of vector based image
representation
(e.g. Adobe Illustrator) but scripting that with php is possibly
going
to be very
tricky, either using a COM object or shelling out to something
like
AppleScript
(which I know you can use to do some really crazy Illustrator
scripting
with)
and to do it on a pixel by pixel basis from within a function is
going
to be a very time consuming and memory costly process. Have you
thought about using ImageMagik to do this? I know that you can
exec()
out to this from within Windows and Linux, and ImageMagik is free
to
use (as far as I'm aware) so
Re: Re: [PHP] Image Generation
Yes, if you wish to stretch text in this way then you will have to
create the image and stretch. You can create the image in memory and
perform the stretching on it there if you are worried about writing too
many temporary images to the server.

Just to clarify some points, there is no need for this to be of
print quality - it is an online representation of the vinyl they will
recieve in the post.
Also, the main problem I've got with GD, is generating text that is
stretched? Do I need to generate a text image then stretch this using
normal resize functions??

As for quality, I've found that GD offers comparable quality

advantage
ImageMagik has is with functionality; quite simply, it can do much
more

I'll take your word on that, I've never played with imagemagick,
having found
GD to produce quality good enough for my needs.

Re: Re: [PHP] Image Generation
Hi Alex,
I did reply to this, but it apparently didn't get to you. You will need
to create a separate image with the text in, as GD offers no function to
create text already stretched (actually, it's text offerings are sparse
to say the least). You can create this image in memory if you are
worrying about creating a lot of files on your server though, and then
perform resizing operations on the image in memory.

[PHP] Image Generation: Centering Text
Hello, I am using the following code. ?php $img_number = imagecreate(100,20); $white = imagecolorallocate($img_number,255,255,255); $black = imagecolorallocate($img_number,0,0,0); $grey_shade = imagecolorallocate($img_number,204,204,204); imagefill($img_number,0,0,$white); $number = $_GET['text']; Imagettftext($img_number, 10,0,4,15,$black,'arial.ttf',$number); header(Content-type: image/jpeg); $rotate = imagerotate($img_number, 270, 0); imagejpeg($rotate); ? But I need to center the text in the image that is generated. As I am using the same font and it is fixed at 10px I was thinking of doing something like: (Get Length of Text in Chars * Width of Average Char) DIV 2. (Width of Image DIV 2) - Above = starting point on the x axis. or can anyone think of a better way to do it?

Re: [PHP] image generation issues
Adrian, If you're using the code displayed, you need to use $im before you destroy it. If you want to deal with it as a .png then use: ImagePNG($im,some_name.png,100); and then pick up the file anytime using img src=some_name.png You can later remove it from the server using: unlink(some_name.png); hope this helps.

[PHP] Image generation scripts
Hi there! I'm writing some stuff for a non-profit site as voluntary help. Does somebody have any PHP image generation scripts (GD) that could be used to pretty up a statistics page. The produced image should be a chart, pie, bars or something similar that could visually represent various statistical information. It would be great if one could specify background images etc. The image should be a bit more beautiful from the pie chart at http://skydiving-org.freeservers.com/stats.htm A bit more customization and visual attraction would be great.

[PHP] Image Generation Library
Hi to all, I need to create web pages containing images which should be updated periodically, but the image contents may vary as data coming from a database varies. What is that?, well the image will contain dynamic objects and static objects. The dynamic objects can be text (representing database data) and lines, where you can change attributes like color, position, etc. The static objects can be filled ellipses, circles, lines, static text. The image format can be a jpeg, gif or another type supported on html. Does somebody know some Library with functions for create such above images? Does somebody know some links to find something? I will apprecciate your attention to this. When you come to Mexico and Guadalajara City I will pay your help inviting you a bunch of Mexican Tacos. Atte. Ignacio Estrada F.

[PHP] Image generation
Hi, I'd like to write some scripts that resize high-res jpegs and gifs into smaller jpegs and gifs. What are the best tools for doing this? I've heard of the GD library and ImageMagick. Which one is better? Are there others? I'll definitely have to generate gif's, so png support by itself isn't sufficient. I'm looking for high quality image manipulation that can be done ideally from PHP, or at least Perl. I'm looking for freeware and we're running PHP4 + Apache on FreeBSD. Thanks for the help.
