This section contains test packages that are structured as one folder containing an XML file with bibliographic information, an img folder which contains the image files of a certain type.
Test Set 1
Test set 1 was kindly prepared by a user of the Hague System: Sterne, Kessler, Goldstein & Fox P.L.L.C.

Test Set 2
This test sets is based on IRN DM/226667, which is an IR that was found to meet a certain number of criteria for this test:
- Published registration
- Initially submitted in vector format (through the USPTO, as a PDF embedded image)
- Fine details in line drawings

Zoom in and observe the blurry lines | With a higher resolution, it takes much more zooming for the lines to blur | PNG does not "blur" details. After zooming enough, you start to see the pixels. For line drawings and high contrast images, PNG is better than JPG | SVG does not show any pixelation at any zooming level, which makes it the most appropriate format for line drawings. (Depending on the browser you use, you might see some pixelation due to how the browser renders the image) |

SVG considerations (script, animation, etc.)
SVG format includes a rich set of features, in particular animation and scripting. Here are important considerations when accepting SVG files in the context of design reproductions.
Self-contained: no external reference
The SVG file must not include any embedded or referenced elements, such as an image file, a script, a stylesheet
Behavior disabled: animations and scripts
The SVG file must not contain any animation, scripts or triggers (i.e. "onload" events)
Page definitions
The SVG file must contain a width and height elements, specified in cm, at the top of the header to ensure a consistent representation on various medium.

Deprecated elements
The SVG file should avoid the use of features that are not commonly supported by browsers.
