Solved Can't set user's cape

I am trying to get custom capes from png files with:

PHP:

$image = imagecreatefrompng($this->getDataFolder() . "cape.png");
$data = '';
for ($y = 0, $height = imagesy($image); $y < $height; $y++) {
    for ($x = 0, $width = imagesx($image); $x < $width; $x++) {
        $color = imagecolorat($image, $x, $y);
        $data .= pack("c", ($color >> 16) & 0xFF) //red
            . pack("c", ($color >> 8) & 0xFF) //green
            . pack("c", $color & 0xFF) //blue
            . pack("c", 255 - (($color & 0x7F000000) >> 23)); //alpha
    }
}

and then setting $data to the capedata paramter in the skin class.
I am pretty sure this is for skins only though and not capes because the post I got this from used it for skins and I get Specified skin is not valid, must be 8KiB or 16KiB. The length of the data is only 4096 characters too. How can I get something like this working for capes only instead?

 

According to this thread, capes have to be 8192 bytes.
P.S: I just googled "pmmp capes" to find this.

 

Methinks you mean 8192 bytes.

@aTmG What are the dimensions of your cape.png?

 

Yep, I meant to check that number before I posted but forgot to. Edited.

 

No, it can be used for capes too.

I've checked this code with a simple script (can't check with PM right now, because my MCW10E has updated to v1.5... ) and it should work fine.

PHP:

<?php

$image = imagecreatefrompng("cape.png");
$data = '';
for ($y = 0, $height = imagesy($image); $y < $height; $y++) {
    for ($x = 0, $width = imagesx($image); $x < $width; $x++) {
        $color = imagecolorat($image, $x, $y);
        $data .= pack("c", ($color >> 16) & 0xFF) //red
            . pack("c", ($color >> 8) & 0xFF) //green
            . pack("c", $color & 0xFF) //blue
            . pack("c", 255 - (($color & 0x7F000000) >> 23)); //alpha
    }
}

echo strlen($data) . " bytes!\n";

Could you please post the "cape.png", that you're trying to read?

 

Alright, I've tried both of these

 

Seems like the pngs are the issue, since they are 744 bytes and 808 bytes respectively. I don't even know if that matters though.

 

As I thought, those are not of the right format. Using this template, you can try to convert them, but they are both larger than a usual cape. As for what causing the problem is that those cape PNGs don't have the large empty area and that's why they're smaller when they're uncompressed.

Red - front
Green - back
Blue - top
Magenta - bottom
Cyan - left and right sides

 

Thank you!
