Opacity in print tool

MatejSkerjanc

I made a print widget out of print task. After few prints i noticed the opaque symbols are rendered non transparent.
Are more complex symbols not supported?

I modified the print sample to use your symbols:

The print output from that page honors symbol transparency.

In your initial post, you said "After a few prints". Does the issue you're describing happen when hitting your print button multiple times? Is it possible that you're adding graphics multiple times which cause them to appear less transparent than you're expecting?

JohnGravois

in a tech support call, Matej and i isolated a problem in REST in which transparency for featureLayer selectionSymbols is not honored in the output created by 10.1 print services. the issue was documented as [#NIM085074 Opacity supplied via a selectionSymbol color tag is not honored in exported web maps. ]. please don't hesitate to contact support if you would like to have your name added to the list of customers affected by the issue.

in the meantime, the best workaround i can think of in this situation is to work with a normal graphics layer instead.

MatejSkerjanc

they dont
Let me show you best example

http://tinypic.com/r/10y2equ/6

left is the application right is the printed png

derekswingley1

http://i50.tinypic.com/14csf7s.png

this is the problem i was refering to, now it's not opaque at all. And i know i had a polygon and i made it opaque once. Now i'm really confused

Should the yellow squares be semi-transparent? How do the symbols used to generate that print output differ from what you posted previously in this thread?

MatejSkerjanc

marked as an answer since i noticed that if i zoom in enough i can see the item is transparent to some extent but really hardly visible. I guess ill have to tone up the opacity factor. Thank you!

MatejSkerjanc

there's only one graphic, no cascading

I think i read about printing not supporting complex symbols, but dont know if source was reliable

oh...just tested your example and it works... Now i have no clue what could be causing it but the dimnished opacity due to cascading was a good call, but it's not the issue here

well the styles for symbols are like this:
pointStyle: new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_SQUARE, 20, null, new dojo.Color([255, 255, 0, 0.5])),
polyStyle: new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol("dashdot", new dojo.Color([255, 0, 0]), 5), new dojo.Color([255, 255, 0, 0.25])),
lineStyle: new esri.symbol.SimpleLineSymbol("solid", new dojo.Color([255, 0, 255]), 5)

And i think this is the JSON you were looking for
f:json

Can you provide an example? The JS used to create your symbol would be helpful, as well as the JSON sent to the print task.
