Magento – How to remove interlacing from the PNG files in magento 2

magento2.2sitemaps

I have added a third-party extension for XML sitemap. When I generate a sitemap, I am getting "Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.". That extension company said,
sitemap generation error is related to your server:

"libpng warning: Interlace handling should be turned on when using
png_read_image"

I googled it found this solution for removing interlacing from the PNG files is using ImageMagick's 'convert' utility:

$ convert in.png -interlace none out.png

but I don't know how to apply it in Magento 2 for all images.
any help would be appreciated

If you mean you want to run this convert command on several png files, you could try:

find . -iname *.png -execdir convert {} -interlace none {} \;

This would be equivalent to running for every .png file:

convert <mypngfilename> -interlace none <mypngfilename>

where <mypngfilename> is, obviously, the name of the png file.

Make sure you try find . -iname *.png first alone to see the results being produced and making sure they are what you need. Also I am also not familiar with the convert command so test it first on one file to make sure that having the <out> file and <in> file being the same name does not cause issues.

That said, I'm quite suspicious that your sitemap would have anything to do with that warning in the first place but I couldn't tell you with 100% certainity.

Magento – Want to remove a specific url from Magento sitemap.xml

Please do not just copy the complete file to app/code/local (as mentioned in the other answer here). This is not upgrade safe and will cause some extra work when upgrading.

It's better to create a seperate module for this, for example YourNamespache_Sitemap with a proper rewrite of the model Mage_Sitemap_Model_Sitemap there.

In your config.xml put the following:

<?xml version="1.0"?>
<config>
    <modules>
        <YourNamespache_Sitemap>
            <version>0.1.0</version>
        </YourNamespache_Sitemap>
    </modules>
    <global>
        <models>
            <yournamespace_sitemap>
                <class>YourNamespache_Sitemap_Model</class>
            </yournamespace_sitemap>
            <sitemap>
                <rewrite>
                    <sitemap>YourNamespache_Sitemap_Model_Sitemap</sitemap>
                </rewrite>
            </sitemap>
        </models>
    </global>
</config>

And in app/code/[local/community]/YourNamespace/Sitemap/Model create the class Sitemap.php which extends the original sitemap model class. You only need to copy and adjust the generateXml() method in there, the rest can stay in the parent class.

class YourNamespace_Sitemap_Model_Sitemap extends Mage_Sitemap_Model_Sitemap {

    /**
     * Generate XML file
     *
     * @return Mage_Sitemap_Model_Sitemap
     */
    public function generateXml()
    {
        //copied and adjusted code from the parent generateXml method
    }
}
