<div dir="ltr"><div>Hi Devs,</div><div><br></div><div>Not too long ago, I wanted to address the issue when drawing legend and scalebar on high resolution images, but it looks like I've run into a couple of discrepancies in the concept, which would require further discussion. This is where we are now:</div><div><br></div><div>1. When drawing high resolution images we will set up the resolution factor (resolution/defresolution) greater than 1 and will increase the image size accordingly. This causes that the symbol sizes lines widths are increased proportionally so as to provide the same look of the map image at the greater size. But the issue is that this is not the case with the embedded scalebar and legend sizes and the related parameters. Therefore I wanted to modify the scalebar/legend drawing code to increase the size related parameters (like scalebar sizes, margins, keysize, keyspacing etc.)</div><div><br></div><div>2. However according to a recent discussion <a href="https://github.com/mapserver/mapserver/pull/5035">here</a> I might think that we would want to keep the user specified sizes (like legend keysize) not to grow proportionally with the resolution factor(?) That means if the user specifies the keysize as an 50x50px image that should be always the same pixel size at all resolutions. (On the contrary we let the specified symbol sizes to grow)</div><div><br></div><div>I'm curious to know what folks do think here (ie. which sizes should grow and which not), before taking any further actions.</div><div><br></div><div>Thanks,</div><div><br></div><div>Tamas</div><div><br></div><br><div class="gmail_extra"><br><div class="gmail_quote">2014-11-05 21:50 GMT+01:00 Lime, Steve D (MNIT) <span dir="ltr"><<a href="mailto:Steve.Lime@state.mn.us" target="_blank">Steve.Lime@state.mn.us</a>></span>:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">

<p class="MsoNormal">I've added 2 issues related to the resolution setting in MapServer. According to <a href="http://mapserver.org/development/rfc/ms-rfc-55.html" target="_blank">RFC-55</a> we expect to get the same look of the map when setting the image size and the resolution
to higher values to get a higher resolution (printable) image. But this is not the case for the scalebar and legend according to:<u></u><u></u></p>
