Issue with viewing SVG files

Post by cday »

SVG files opened in XnView MP using the included plugin open at reduced pixel dimensions, in the case of the attached example file at 100x100 versus 450x450 pixels when opened in another popular freeware software.

As originally reported in the following thread: svg to png: bad quality

Edit: As a vector file as no associated DPI value until it is rasterised when it is opened, presumably the file is being opened at a lower DPI value in XnView software, due to a value set in the addon used or set in XnView software.

A parameter in the SVG file, so no way to view at higher resolution using the included plugin?

It is a surprise that a vector file format specifies viewing pixel dimensions.


Edit:

A web image standard, rather than a typical image format:

On further investigation, SVG is evidently more than a vector image format, the specification allowing other forms of image content including bitmap content:

Wikipedia - Scalable Vector Graphics


It remains unexplained why the 'other' software renders the same file with significantly larger pixel dimensions, and correspondingly much improved image quality... :?:

I am encountering the same issue. In other softwares, when loading an SVG format, you get usually prompted for import resolution during the rasterisation process. I think XnConvert is ignoring the "Resolution" property from the "PS/PDF" tab of the "Load Format Setting" which should be the intended behaviour...
