Yes, it is.
Do you add this before 1.0 release?

------------------------------------------
This should work in 1.0, with BMP, PCX, PNG, and TIFF:
{code}
Map params = new HashMap();
params.put(SanselanConstants.PARAM_KEY_PIXEL_DENSITY, PixelDensity.createFromPixelsPerCentimetre(300, 300));
Sanselan.writeImage(image, outImgFile, format, params);
{code}

Damjan Jovanovic commented on SANSELAN-67:
------------------------------------------
You are meant to set DPI using parameters passed to Sanselan.writeImage(), as shown in the example below:
{code}
Map params = new HashMap();
params.put(SanselanConstants.PARAM_KEY_X_RESOLUTION, Integer.ValueOf(300));
params.put(SanselanConstants.PARAM_KEY_Y_RESOLUTION, Integer.ValueOf(300));
Sanselan.writeImage(image, outImgFile, format, params);
{code}
But this only works when writing BMP and TIFF images at the moment. I'll have to add it to other formats like PNG as well.
