Magento 1.9 – How to Increase Logo Image Quality for PDF Invoices

invoicemagento-1.9pdf

I would like to increase the quality of the logo in the PDF invoices. At the moment I upload a logo exactly 200×50 px in size and with JPG quality 99 and it still looks terrible. I also tried PNG24 without any better results. If I upload a larger logo, it is embedded larger but the quality is still shit.

Could anyone point me in the right direction? I'm familiar with PHP and coding, if that is what it takes.

Thanks!

The key to increasing the image quality is to keep the image uploaded at the same ratio of 200x50px, but at a higher resolution, so a 400x100px image will look better, or a 600x150px image, etc.

I've found if you don't keep the same ratio as the settings it will make the image quality look terrible.

Magento – Totals for emails and pdf invoices

It helps to take a look at how Magento implements it - most totals are added in the sales module in /app/code/core/Mage/Sales/etc/config.xml

For example the subtotal is defined here

<config>
    <global>
        <!-- SNIP -->
        <sales>
            <!-- SNIP -->
            <quote>
                <totals>
                    <subtotal>
                        <class>sales/quote_address_total_subtotal</class>
                        <after>nominal</after>
                        <before>grand_total</before>
                    </subtotal>
                </totals>
            </quote>
        </sales>
    </global>
</config>

and for the pdf here

<config>
    <global>
        <!-- SNIP -->
        <pdf>
            <!-- SNIP -->
            <totals>
                <subtotal translate="title">
                    <title>Subtotal</title>
                    <source_field>subtotal</source_field>
                    <font_size>7</font_size>
                    <display_zero>1</display_zero>
                    <sort_order>100</sort_order>
                </subtotal>
            </totals>
        </pdf>
    </global>
</config>

Use the above configuration in your own module's config.xml file as a start, Adjust subtotal = your total code. Further places to look into

Magento – Can’t generate PDF invoices or packing slips in Magento

as user2694249 said correctly, the problem is a missing backwards compatibility of magento relative to php 5.3/4

The "bug" is already fixed in the newer Zend_Framework 1 versions, but magento has old versions shipped with it.

The bug is fixed with a patch, magento offers. A EE fix is accessable via your internal account area.
