[solved] Import a pixellated image (no smoothing)

Postby jspudross » Fri Apr 29, 2016 9:36 pm

Dear all,

I have an image about 50x50 pixels, each pixel is effectively a data point and i want to maintain each of those pixel values, however when i copy and paste or import a file of the image inkscape smooths out the pixels so the initial intensities are lost.

How would i go about asking inkscape to leave the image in its native state. FYI, i will also require to increase the size of this picture so that each pixel is clearly distinguishable upon printing.

Thanks very much!

Preferences -> Bitmap -> Bitmap scale (image-rendering) ?

Are you sure your image is still 50x50px when you paste it ?
Because of Inskcape default resolution, a 50x50px image has a size of 62,5x62,5px when pasted.
Maybe thats why its blurry ?

Attached is the original image (on the left) opened with imagej in which you can see the pixilation i required, however (on the right) when copied and pasted or imported into inkscape, i get the image on the right.

I'm not sure how i would know the resolution 'when pasted' Superficailly, it looks likes there is about 9 to 16 adittional pixels per original pixel, with a smooting effect applied.

Thanks

Right-click on the image, select 'Object Properties' and in the dialog that opens, at 'Image rendering', select 'Optimize Speed'.
