Hi,

I'm trying to export file as a png form.

But it seems loosing some image quality.

How can I avoid this?

I did increase dpi 300 and 600 but there was no difference.

I also attached the file that I want to export to png with high resolution.

How can I increase resolution just like svg file?

Thank you in advance.

* I'm using the newest version of Inkscape and Mac OS Ventura 13.0.1

You´re saying eg 1500px vs 3000px don´t make any difference? I don´t get it

I mean perhaps there is a difference but for me it looks the same.

This is what I've got from inkscape with 300 dpi.

and I doubt that I could use this resolution for publication or official usage.

If I zoom in pixel then I can see squared pixel in the outline but in Inkscape even I zoom in the outline is very smooth.

But this is exactly the difference between vector- and raster-graphics. If your target application allows SVG go for it - otherwise: Your stroke width is just 0,189 of a pixel.

yeah that resolution is what I want.

I've tried to export PNG with 300 pHYs dpi. but still same poor resolution.

But if I export to PDF with 300 dpi the resolution is also very good.

I don't understand why my png export has a low resolution while pdf file has desired resolution.

How can I get those good resolution of png ? (the left, below one)

My setting is image size with 274 width px, 129 Height px. and set to 96 dpi but in advance setting I set it into 300 pHYs DPI.

The main dpi setting, for png is really just a helper function - it simply is a convenient way to set the image resolution x and y values.

Use that dpi setting

---------

pHYs dpi is an advanced option, it should not be confused with simple dpi.

I would leave it set a default values, unless you can read and understand the link below - or have been told to use it for a specific target display system.

Thank you so much!

It's solved.
