Export bitmap options; scale greyed out

[FrankBlakely]

The bitmap size and dpi are linked in jpg and png export dialog with the scale box greyed out. When exporting a vector image, why can't I scale the dpi independent of the width/height? The manual doesn't say anything about it. I understand if I were trying to export a bitmap image but not a vector one.

Hi Frank, never even noticed the scale greyed out. However this option only works for non-jpg's & non-png's. It becomes active if your exporting as bmp or gif.

Scale: (Dimmed for JPEG & PNG). This lets you scale the bitmap up or down by a percentage. Scale is more suitable than Size if you want, for example, a bitmap 50% bigger than the original.

To scale a jpg or png, export it at greater dpi, 192, 300, 600 etc. This changes the pixel dimensions.

Also remember all the exports apart from pdf and svg no longer remain as vector but become raster images.

Thanks for the reply. It just doesn't make sense that width/height and dpi can't be changed independently before it becomes a raster image on export. Not that important, of course.

width/height and dpi

But Width & Height are linked to dpi & vice versa.

If you need to, scale before you export. Once you export to PNG or JPEG or any other bitmap format, the exported image is no longer editable. It is now a bitmap.

And as far as I know you cannot scale independently in vector formats either.

Thanks guys. Guess I'll just scale in the program. ctrl-k doesn't take long. (making multiple sized versions of my logo, for example.)
