Graph DPI forcing large dimensions

Howdy!

I have to create a 1200 DPI TIFF graph for a colleague for a journal submission. The graph is very simple, but the file size is huge (> 100 MB). When I view the properties of the TIFF, it is indeed 1200 DPI. It is also uncompressed. Is there a way for SAS to produce a compressed TIFF file? That might make the file size more manageable.

I can zip it up really well, so no worries if there's not a way.

ods html close;
ods listing style = axis_wall image_DPI = 1200;
ods graphics / reset width = 6.5in height = 4in scale = off noBorder outputFMT = TIFF;
%let xAxis = grid /*type = log*/                   label = "Relative Risk with 95% Confidence Limits" labelAttrs = (family = "Calibri" size = 11pt)  values = (/*0.4 0.5 0.6 */0.7 to 1.8 by 0.1/* 2.5*/) valueAttrs = (family = "Calibri" size = 11pt)  min = 0.4 max = 2.5 offsetMin = 0.03 offsetMax = 0.03;
proc sGPlot data = a dAttrMap = GraphAttrMap;
    refline 1 / axis = x;
    scatter y = group x = PE / xErrorLower = LL xErrorUpper = UL group = noise attrId = Noise errorBarAttrs = (pattern = longDash thickness = 2);

    xAxis grid /*type = log*/               label = "Relative Risk with 95% Confidence Limits" labelAttrs = (family = "Calibri" size = 11pt)  values = (/*0.4 0.5 0.6 */0.7 to 1.8 by 0.1/* 2.5*/) valueAttrs = (family = "Calibri" size = 11pt)  min = 0.4 max = 2.5 offsetMin = 0.03 offsetMax = 0.03;
    yAxis grid discreteOrder = data reverse display = (noLabel)                                labelAttrs = (family = "Calibri" size = 11pt)                                                       valueAttrs = (family = "Calibri" size = 11pt)                      offsetMin = 0.1  offsetMax = 0.1 ;
    keyLegend / titleAttrs = (family = "Calibri" size = 11pt)  valueAttrs = (family = "Calibri" size = 11pt);
run;

From the documentation: about Universal Printing:

SAS supports TIFF 6.0 for RGBA and CMYK colors.

When SAS creates a TIFF image, the image is compressed.

If the NOUPRINTCOMPRESSION is set, the size of a TIFF image file that SAS creates is extremely large.

Have you tried that syntax and that option?
