Subject: Re: [office-comment] Insufficient description of output filter draw:luminance and draw:contrast
Regina, Thanks!Do you have suggestions/pointers to better definitions for luminance and/or contrast?
Thanks! Hope you are having a great day! Patrick On 03/11/2013 10:35 AM, Regina Henschel wrote:
Hi all, compared with draw:blue the description of draw:luminance and draw:contrast is not sufficient to implement these attributes. Please read the specification of "20.94 draw:blue" and then compare it with those from "20.105 draw:contrast" and "20.135 draw:luminance": "The draw:luminance attribute specifies a signed percentage value that sets the output luminance of a bitmap or raster graphic." "The draw:contrast attribute specifies a signed percentage value that sets the output contrast of a bitmap or raster graphic." These attributes do not "set" luminance or contrast. But both attributes are used in a mapping of the original RGB-values to the output RGB-values, together with the draw:red, draw:green and draw:blue values. Kind regards Regina
