stil / gd-text Goto Github PK

When I am drawing I'm getting a blur(2%) or less clarity text on the image.I checked the ttf and it seems good.Please reply ASAP.

please am new to composer and it really strange to me, please hw can i use these library in my web app .
please help me, thanks

Hi I want to use the project to write text on an image inside a box. So I need a function where I can set max width and height of the text not just max width and height of the textbox. So it should scale down the text until it fits inside the box.

I don't know how to use gd-text, I can't get defined the imageftbbox function. I think I have all php and gd installed but it's impossible to run this.

The error I get:

Fatal error: Call to undefined function GDText\imageftbbox() in /vendor/stil/gd-text/src/Box.php on line 383

Does anybody know how can I do?

Thank you!

Hiya,

I noticed the examples in the README reference a setLeading() method, but it looks like that method doesn't actually exist. Are you planning to implement it?

Cheers, Craig

Great library.Keep it up . I am using it on our site.Very Helpful.Can I add Font Styles like Bold,Italic or give it some Stroke.

Is there a method to change the text color per character?

Maybe this is not an issue but it can be a helpful answer that can save time for programmers who are speaking Persian (Farsi) or Arabic.

As you know, we cannot directly pass Persian (or Arabic) to $box->draw which $box is an instance of GDText::Box.

For example, if we have a text like:

همدان قدیمی‌ترین شهر ایران و از کهن‌ترین شهرهای جهان است. نخستین باری
که اسم این شهر برده شد، در حدود ۱۱۰۰ سال پیش از میلاد بود که نام همدان
را اَمدانه ذکر شده‌است.

and we directly pass it to the box, it will be like:

So we have to use a library like persian phpgd by @slashmili which will return an output like:

Natives know that the output is in reverse order.

را امدانه ذکر شده است
از میلاد بود که نام همدان
در حدود ۱۱۰۰ سال پیش
که اسم این شهر برده شد،
جهان است. نخستین باری
ایران و از کهن‌ترین شهرهای
همدان قدیمی‌ترین شهر

It should be:

همدان قدیمی‌ترین شهر
ایران و از کهن‌ترین شهرهای
جهان است. نخستین باری
که اسم این شهر برده شد،
در حدود ۱۱۰۰ سال پیش
از میلاد بود که نام همدان
را امدانه ذکر شده است

Solution

So changes are required in Box.php:

+     /**
+     * @var reverse_text_lines_order
+     */
+    protected $reverse_text_lines_order = false;

+     /**
+     * @param bool $reverse_text_lines_order To Reverse Lines Order
+     */
+    public function setReverseTextLinesOrder($reverse_text_lines_order)
+    {
+        $this->reverse_text_lines_order = $reverse_text_lines_order;
+    }

Then use the new prop inside draw function:

             }
             $lines[] = $line;
         }
+        if ($this->reverse_text_lines_order == true)
+            $lines = array_reverse($lines);
         return $lines;
     }

In your main class you have to detect Persian (or Arabic) with following regex and then pass a parameter to $box:

   if (preg_match('/.*[چﺞﺤﺨﻬﻌﻐﻔﻘﺜﺼﻀﺸﺳیﺏﻼﺘﻨﻣکگﻭپﺩﺫﺭﺰﻄﻇژ].*/u', $text)){
       $text = fagd($input,'fa','vazir');
       $box->setReverseTextLinesOrder(true);
   }

So the output will correctly be:

Hi,

When creating text within a white background, text shadow gets badly shaped (at least for me). To solve it, i rewrote the "Color->getIndex()" function. It works fine for me now:

/**
 * @param resource $image GD image resource
 * @return int Returns the index of the specified color+alpha in the palette of the image,
 *             or -1 if the color does not exist in the image's palette.
 */
public function getIndex($image)
{
    $color = -1;
    if ($this->hasAlphaChannel()) {
        if(($color = imagecolorexactalpha(
            $image,
            $this->red,
            $this->green,
            $this->blue,
            $this->alpha
        )) == -1){
            $color = imagecolorallocatealpha(
                $image,
                $this->red,
                $this->green,
                $this->blue,
                $this->alpha
            );
        }
    } else {
        if(($color = imagecolorexact(
            $image,
            $this->red,
            $this->green,
            $this->blue
        )) == -1){
            $color = imagecolorallocate(
                $image,
                $this->red,
                $this->green,
                $this->blue
            );
        }
    }
    return $color;
}

What should i do?
thanks..

Do this package support Arabic language, when I write text on image in Arabic , i get inversed direction and letters separated

Hello,

How could I use this code in a basic PHP? I just want to use a form to put name and author and generated.

I had copied and pasted the code into a new .php but apparently this code needs a framework for living.

I just want to use it for a very basic code , how can I use it?

A greeting,
Angel.

Is there any function to setFontSize dependent on image size (px) ?
I want the text to be extended (fontsize set) over the whole width of the image (and height - multiline)

Hi, first really big applause for this amazing work. Actually I need to ask, can we calculate the height and width for given text before drawing?
Mean suppose we got dynamic text, can we get the width and height relative to text?

Like how will I know at which coordinate the first paragraph has an end and set the box size accordingly for the 2nd para and onwards?

Basically, I'm trying to create a dynamic image like this How can I set the box size for "Hello!", then the next line and so on?

Why calculateBox() is not a public method?

Hi, how can I display 2 different fonts in the same text separated by a new line?

$font1 = "font1.ttf";
$font2 = "font2.ttf";
$text1 = "text";
$text2 = "text2";

$box = new Box($im);
$box->setFontFace($font1);
$box->setFontColor(new Color(255, 255, 255));
$box->setTextShadow(new Color(0, 0, 0, 50), 2, 2);
$box->setFontSize(35);
$box->setBox(100, 150, 500, 400);
$box->setTextAlign('center', 'center');
$box->draw($text1."\n".$text2); // here only displays the second text with the font1

Hi, gd-text not supporting utf-8. Promptly it need to fix. Otherwise I will have to choose another framework.

strokeText is very slow for high input (eg 10).

The following code is much more efficient (up to 40 times faster for strokeText = 10)

protected function strokeText($x, $y, $text)
    {
        $size = $this->strokeSize;
        if ($size <= 0) return;

        /*
        // Current algorithm
        for ($c1 = $x - $size; $c1 <= $x + $size; $c1++) {
            for ($c2 = $y - $size; $c2 <= $y + $size; $c2++) {
                $this->drawInternal(new Point($c1, $c2), $this->strokeColor, $text);
            }
        }
        */

        $tmp_box = $this->calculateBox($text);

        $textWidth = $tmp_box->getWidth();
        $textHeight = 1.5 * $tmp_box->getHeight();

        $tmp_img = imagecreatetruecolor($textWidth, $textHeight);
        imagesavealpha($tmp_img, true);
        imagefill($tmp_img, 0, 0, imagecolorallocatealpha($tmp_img, 0, 0, 0, 127));

        imagettftext(
            $tmp_img,
            $this->getFontSizeInPoints(),
            0, // no rotation
            0,
            $tmp_box->getHeight(),
            $this->strokeColor->getIndex($tmp_img),
            $this->fontFace,
            $text
        );

        for ($c1 = $x - $size; $c1 <= $x + $size; $c1++) {
            for ($c2 = $y - $size; $c2 <= $y + $size; $c2++) {
                imagecopy($this->im, $tmp_img, $c1, $c2 - $tmp_box->getHeight(), 0, 0, $textWidth, $textHeight);
            }
        }

        imagedestroy($tmp_img);
    }

I've got problem with drawFitFontSize - works till go closer to border (when fontSize is bigger or text longer) - then 503 error or:

Fatal error: Maximum execution time of 300 seconds exceeded in XXX/public_html/gdtext/vendor/stil/gd-text/src/Box.php on line 476

I'm using #30

Function draw works well
Function should reduce the size of text, but something is wrong and results is 503/statement up^

how is the support for other languages such as Chinese? I have tried on my side but its not working well. It overflows.

I can't find help on how to install gd-text? it looks it's depending on something else.

Hi, first time writing.
Is there a way to set padding to control the background color?
It could be great for styling bloc text deeper.

I have absolutely no problems using this class. Straight in with composer and within 1 hour I'd built a meme generator.

I cannot thank you enough for making this public. If I had to do this with pure GD, I would still be working on the project next month.

Is there any way to align the text as "justify"?

Hello , i was Trying to Make blur to image using intervention images then pass to gd text to add text
was wonder if this possible and how to implement the two libraries to work together maybe to achieve what i want

Hello,

When I am writing hindi text on the image that will show in square block.

Can you let me know how to wrote multi language text on image.
https://ibb.co/17mYqSs

Thanks in advance.

in Arabic language this disconnect letters and change order of lines

I want to have a block of text center vertically and horizontally, and then after it a line that is right aligned, is this possible?

Is there any way to change the orientation from horizontally to vertically?

font: https://fonts.google.com/specimen/Khmer
I have type: ខ្មែរ but working not good

Error: https://www.dropbox.com/s/wyfyuc1erzwei0x/khmer_error.jpg?dl=0

Since we already have a drawFilledRectangle method, this is pretty trivial to do. :) Will make a PR soon.

Could you add the adaptability of the size of the font.
Calculating the size of the font depending on the length of the text. This will allow small texts to see more clearly, bigger.

I don't see anywhere how I can specify using an already indexed color (if I know only the index), can it be done?

Also, what happens if the color palette is already full & you try to assign a new color?

• Installation request for stil/gd-text ^1.1 -> satisfiable by stil/gd-text[v1.1.0].
  stil/gd-text v1.1.0 requires ext-gd * -> the requested PHP extension gd is missing from your system.

can i use this on native PHP ?

Hi background Can I add any image I want?

You script look interesting but there's no example how to use it.

Can you provide some example?

Problem 1:

• The requested package stil/gd-text No version set (parsed as 1.0.0) is satisfiable by stil/gd-text[No version set (parsed as 1.0.0)] but these conflict with your requirements or minimum-stability.

I'm running on WAMP, apache 2.4.23, php 7.0.10. Any ideas?

Would it be possible to have an extra alignment type (fully justified text) ?

Thanks,

Need rounded corner feature!

Is it possible to set the text rotation?

There are several open issues asking for text measurement. I want to propose new API for upcoming gd-text release and I invite you to discuss.
