How do you overwrite the view.xml in vendormagentomodule-swatchesetcview.xml in your own template?

I want to overwrite the sizes for swatch_image and swatch_image_base. I tried putting the code in ...mythemeetcview.xml and in ...mythemeMagento_Swatchesetcview.xml but it does not work.

The other theme stuff works, so the theme is correctly set up.

Changing the values directly in the original view.xml works as well.

Edit: Full Code in appdesignfrontend\Vendor\themeetcview.xml

<?xml version="1.0"?>

 <image id="swatch_image" type="swatch_image">

 </image>
 <image id="swatch_thumb" type="swatch_thumb">

</view>

You have to apply changes under app/design/frontend/Package/themename/etc/view.xml file.

For changes value of swatches you have to add your tag inside view.xml files

<media>
 <images module="Magento_Catalog">
 <image id="swatch_image" type="swatch_image">
 <width>30</width>
 <height>20</height>
 </image>
 <image id="swatch_thumb" type="swatch_thumb">
 <width>110</width>
 <height>90</height>
 </image>
 <image id="swatch_image_base" type="swatch_image">
 <width>30</width>
 <height>20</height>
 </image>
 <image id="swatch_thumb_base" type="swatch_thumb">
 <width>110</width>
 <height>90</height>
 </image>
 </images>
</media>

You can keep your specific field inside images tag.

Now applying changes you have to clear cache and var folder.

Looks like M 2.1.x has some issues with this.
Not only is needed to add your own <media> tag in app/design/frontend/Package/themename/etc/view.xml as already mentioned:

<media>
 <images module="Magento_Catalog">
 <image id="swatch_image" type="swatch_image">
 <width>30</width>
 <height>20</height>
 </image>
 <image id="swatch_thumb" type="swatch_thumb">
 <width>110</width>
 <height>90</height>
 </image>
 <image id="swatch_image_base" type="swatch_image">
 <width>30</width>
 <height>20</height>
 </image>
 <image id="swatch_thumb_base" type="swatch_thumb">
 <width>110</width>
 <height>90</height>
 </image>
</images>

but, as is written in this issue https://github.com/magento/magento2/issues/6382, you'll need to add a DI to override for MagentoFrameworkViewConfig::getViewConfig() in your module. Make you own class VendorThemeFrameworkViewConfig and copy the getViewConfig() method from the original class.

You should replace line 74 from

$config = $this->viewConfigFactory->create($viewConfigParams);

to

$config = $this->viewConfigFactory->create();

I've tried myself and worked after cleaning the cache.
