Graphic Form Text

remymunich

Hi Folks,

I am a newbie progger and I would like to make the following:

I have scanned a Original blank (Print)Form and saved it as a jpeg.
Now I would like to create a form, which could be filled out and send. When it's send, the Input should be placed onto the original jpeg on several position in the form and then it should be created a new jpeg, which should be printable. This new Form must be a mix from the inputs from the formdatas and the original Form jpeg.

Now my question: what are the functions, to create a new image form the original and the input datas from the online form? and how to position the texts on this form?:rolleyes:

You'll need GD installed. See http://www.boutell.com/GD/ for more information.

You said you're using a JPEG, so you'll need to use:
$im = imagecreatefromJPEG("/path/to/original.jpg");

Then, to add text, you can use either of two methods, one obviously being easier than the other:
imagestring(image,font,x,y,string,color)
imagettftext(image,size,angle,x,y,color,fontfile,text)

Color is supplied by allocating a RGB value:
$color = imagecolorallocate(image,r,g,b);

Now, output the final image:
imagejpeg($im);

In a whole, use something like this:

<?php
$im = imagecreatefromjpeg("original.jpg");
$white = imagecolorallocate($im,255,255,255);
$black = imagecolorallocate($im,0,0,0);
imagestring($im,1,10,100,"text at (10,100)",$black);
imagedestroy($im);
?>

wow, this was verry quick.... :eek:
Thanks ... I will try it!!!

When I'm bored, I sit around on here... I have nothing better to do. 🙂

I hope you can use the code well.

remymunich

WOW, it functioned!
Thanks again!
what does the number 1 mean in the Function :

imagestring($im,1,10,100,.....

and can i use more than one string to place it in this jpg?

just like:

<?php
$im = imagecreatefromjpeg("original.jpg");
$white = imagecolorallocate($im,255,255,255);
$black = imagecolorallocate($im,0,0,0);
imagestring($im,1,10,100,"text1",$black);
imagestring($im,1,40,200,"text2",$black);
imagestring($im,1,40,280,"text3",$black);
imagedestroy($im);
?>

The "1" is the font. There are 5 built in fonts (1-5), each differs in some way. You can also use imageloadfont() to change the font.

And yes, you can use it as many times as you want.

do most servers had GD Installed?

Mordecai

There's no real way to say. It's not naturally installed, but I'm sure a lot of servers do allow for their users to have it.

Thank you Mordecai,

I think gd is not installed on webaccount, but I will ask this.
The other one functioned with multiple text.

So I have only one question left...

The image, which is being produced is too large, but I need it to be large, that the Form is readable. But how can I let this form print out, fitting a printer page (I had to reduce the output to 40% of the original size).

Are ther any functions to resize the image only for printing, like the width and height tags in HTML, if I only want it to be displayed smaller?

Mordecai

Through PHP, all you could do is resize the image entirely. Through HTML, you could use the width and height.

If you want to resize the image in PHP, use this little function:

function imageresize(&$im, $width, $height) {
$buffer = imagecreate($width,$height);
$origw = imagesx($im);
$origh = iamgesy($im);
imagecopyresized($buffer,$im,0,0,0,0,$width,$height,$origw,$origh);
imagedestroy($im);
$im = imagecreate($width,$height);
imagecopy($im,$buffer,0,0,0,0,$width,$height);
imagedestroy($buffer);
}

Note: This will destroy the original image. (Not the .jpeg, but $im.)

Is there a way to have a visitor enter info into a form and choose the color? I'd like to have a textbox, a choose font face dropdown and a choose font color dropdown. I have the first two figured out, but the last one just keeps giving me black and the font color with no deviation. Anyone? Please.
