Export to SVG does not uses DPI setting

[Stephane Guerin]

I'm using Designer to produce an SVG used by my CNC (Shaper origin).  It requires a SVG file at 72 DPI. I'm using the Export function and set it at 72 DPI.  However, Designer ignored the value and output everything at 300 dpi. I've included all the files showing the problem. Here the setting I've used.

Hi @Stephane Guerin,

I've opened your 72 and 300 DPI .SVG files on both desktop and iPad, they both appear to report 72DPI when checking within the Resize/Document Setup Menu. When I export out your .afdesign file following your Export settings,  I then open the exported .SVG it reports that the document is 72DPI. However, there was a noticable inconsistency when comparing the SVG export from Desktop and iPad in terms of document dimensions:

- On Desktop, The exported .SVG result re-scaled the from it's original dimensions 3300x2550px to 792x612px @72DPI

- On iPad, the SVG result retained it's original dimensions 3300x2550x @72DPI

I don't believe this is working as expected on iPad as it has retained the same pixel dimensions, causing the physical dimensions (Inches) to drastically increase in the exported SVG. To clarify, Is this the above the issue you're encountering?

Hi @NathanC

An SVG file is a simple text file.  You can open it with any text editor.  I've check my exported files and there is no dpi information stored in it.  So, I think Designer fall back to 72DPI when it does not know the value.  I don't have access to the desktop version. Can you upload a exported files (or check in the text editor)?

I think you are right, the iPad and the desktop version should output the same exact result.

This is the same with my exported .SVG files, no DPI value is visible/embedded within the SVG contents when it's viewed in a text editor, so it would make sense that it's defaulting to 72DPI when it's opened in Designer.

Though, as mentioned previously when exported from iPad it's not re-scaling the pixel resolution within the SVG file when it's exported out as 72DPI to retain the 11x8.5" dimensions as it does on Desktop so i've now logged this with the developers.
