imagecolorallocate(): Red component is out of range - php

I have a issue with PHP 7.4.5 and GD. I have an image manipulation script and sometime I get this error:
imagecolorallocate(): Red component is out of range
Anybody has an idea how to avoid this?
$image = imagecreatetruecolor($calcWidth, $calcHeight);
for ($y = 0; $y < $height; ++$y) {
for ($x = 0; $x < $width; ++$x) {
[$r, $g, $b] = $pixels[$y][$x];
$allocate = imagecolorallocate($image, $r, $g, $b);
imagesetpixel($image, $x, $y, $allocate);
}
}


I fixed it with this condition, because sometimes an r/g/b value was 256 and rgb can only have up to 255:
[$r, $g, $b] = $pixels[$y][$x];
if($r > 255) { $r = 255; }
if($g > 255) { $g = 255; }
if($b > 255) { $b = 255; }
if($r < 0) { $r = 0; }
if($g < 0) { $g = 0; }
if($b < 0) { $b = 0; }

Pie chart problem does not show if data is missing

I have a PHP pie chart which uses data from Mysql to show the chart. However if one data is missing the whole chart turns to one color. For example for grading if the input is A, B, D and F(pay attention C grade input is missing) then the whole pie chart is in one color like Orange or red.
Can you please help me with this? Thanks

Replace a color with another color in an image with PHP

Yes I know there are related questions available on stackoverflow but they are not perfectly work as per my need. I am trying to replace a color of an image with another color. In below code I am replacing (255,0,255) with (0,192,239).
Below code works but not perfectly replacing new color over pink(255,0,255) color some minor dots or border of pink color is still remaining as you can see in output image.
How can i get its perfect solution ?
<?php

$out = imagecreatetruecolor(imagesx($im), imagesy($im));

imagefill($out, 0, 0, $transColor);
for ($x = 0; $x < imagesx($im); $x++) {
for ($y = 0; $y < imagesy($im); $y++) {
$pixel = imagecolorat($im, $x, $y);

EDIT :
Better solution - determine if color needs replacement (using this method). Determine replaced color's hue (I have no idea if it's correct term, what I mean is lightness and darkness). Apply it to replacement color to give it a shade or AA feeling.
So, as I have said in my comment, you need to determine if this color is really ping (dark, light, etc.). Easiest solution is to apply absolute error method for specific color channels. There may be (there definitely is) better universal method, but I hope this will do:
$color = [255, 0, 255];
$colorAbsoluteError = [150, 0, 150];
$replacementColor = [0, 192, 239];
$filename = 'img/Mascots_Aviators_General-copy.png';
$im = imagecreatefrompng($filename);
$out = imagecreatetruecolor(imagesx($im), imagesy($im));
$transColor = imagecolorallocatealpha($out, 254, 254, 254, 127);
imagefill($out, 0, 0, $transColor);
for ($x = 0; $x < imagesx($im); $x++) {
for ($y = 0; $y < imagesy($im); $y++) {
$pixel = imagecolorat($im, $x, $y);
$red = ($pixel >> 16) & 0xFF;
$green = ($pixel >> 8) & 0xFF;
$blue = $pixel & 0xFF;
$alpha = ($pixel & 0x7F000000) >> 24;
if ((($red >= $color[0] - $colorAbsoluteError[0]) && ($color[0] + $colorAbsoluteError[0]) >= $red) &&
(($green >= $color[1] - $colorAbsoluteError[1]) && ($color[1] + $colorAbsoluteError[1]) >= $green) &&
(($blue >= $color[2] - $colorAbsoluteError[2]) && ($color[2] + $colorAbsoluteError[2]) >= $blue)){
$red = $replacementColor[0];
$green= $replacementColor[1];
$blue = $replacementColor[2];
}
if ($alpha == 127) {
imagesetpixel($out, $x, $y, $transColor);

Using PHP to grab a simplified colour palette from an image?

So far I have found examples on how to grab all the RGB values of each pixel in an image but I want something that will break down an image and give me a simplified color palette.
Is there a way to use imagetruecolortopalette to somehow spit out the reduced palette colours, or to break an image into 25 x 25 blocks and then grab the average value of that block?
Maybe there is an alternative I'm missing? I basically just want to be able to find the most common colors within an image.
Thanks in advance.

Hmm, well I have had created something like this for a client. The screenshot is below
The complete code is as follows

the looping around is more complex, as I have to get the pallet from the DB and to match the colors with them, and also the template parser is used which is full custom code, and will not help you.
Just ignore the Required Weight column from this, the single occurrences and multiple occurrences are calculated, if there is a single pixel, for example RED, RED, BLUE, RED, RED it will be 1 single occurrence and 2 multiple occurrence

I find this code on http://code.google.com/p/fluxcp/source/browse/branches/fluxcp-1.0/modules/guild/emblem.php?r=696
Can you help me.
EDIT::
A solution
from binascii import unhexlify
import zlib
import Image
from cStringIO import StringIO
data = StringIO(zlib.decompress(unhexlify(sdata)))
i = Image.open(data)
i.show()

The solution (in collaboration with OP) is:
import PIL
from binascii import unhexlify
import zlib
from cStringIO import StringIO
sdata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
fh = StringIO(zlib.decompress(unhexlify(sdata)))
image = PIL.Image.open(fh)
PIL is the Python Imaging Library, and using StringIO, I pretend to have a file-like object.

Piechart creation in pdf file using fpdf in php

I want to create piechart in my pdf file created using fpdf. already i had created pdf with fpdf . then i want to create pie chart in that using same table data, is there any option to create pie chart using fpdf ?

Thanks in advance

Try this make changes in code as per your requirements:
You can display following view file on your pdf using pdf helper.
you can use dom pdf helper download it from following link.
