Any transparency layer gets lumped in with the images pdf layer. ESRI Help From the advanced pdf features section: Layers that cause rasterization, such as transparent layers, or layers that use a picture fill symbology consolidate all the layers below them into a single layer with the name Image .

As per ArcObjects docs IColor.Transparency Property: Transparency is the degree to which a color is opaque. True transparency is only supported at the layer level. For graphic elements, 0 for transparent and 255 for opaque are the only supported values. Use either the ILayerEffects or ITransparencyRenderer interfaces to set layer transparency. For layer ...

You can make transparency vary for each category using a field value if you click the Advanced button in the Symbology tab (EDIT: available in 10.0). Now you have to see what's more convenient between adding and populating a field with the percentage, and duplicate the layer as @artwork proposes. The first option will surely save extra work if you need to ...

As @Brad already answered - not possible. Transparencies are rasterized in the PDF resulting in HUGE file sizes. Very very poor PDF engine in ArcGIS as you no doubt have realized. You can turn the transparencies off then export to PDF and open in Illustrator or CorelDRAW and apply transparencies in post processing. Time consuming but possible. Do not ...

A little python script like this would do it for layer in iface.legendInterface().layers(): layer.renderer().setOpacity(0.2) Just copy and paste that into the python console (which is shown via Plugins->Python console) and hit enter twice. The script will loop through all layers and set their opacity to 20%.

Transparency is not a property of a polygon itself, rather it is a property of the layer containing the polygon (like symbology). Take your polygon data, and store it in an IFeatureLayer. From IFeatureLayer, get ILayerEffects, which is an interface of IFeatureLayer. Transparency (0% to 100%) is a property of ILayerEffects. Also, note this from ESRI ...

From your first link, your features must be polygon features. You have point features. You can buffer your points to create polygons from them, after which you should have the Transparency option in the Symbology-Advanced dropdown: This option should be present in all versions of ArcGIS since 8.1. See also this answer: Creating symbology for multiple ...

Similar to whuber suggestion (using geoprocessing tool) you can create this look by: Create temp polygon shp, and digitize a large feature over all features that you want to mask out. Use the Erase tool to erase the temp polygon from your AOI layer. The resulting layer, from the erase operation, you can load into ArcMap and give it a transparency. This ...

The best way to import symbols in a map document is to use EMF format. This will maintain the vectors, allow resizing in ArcMap without loss of quality. Since there is no "background" to a vector drawing, it will appear correctly transparent in ArcMap. Alternately, you can make the bitmap marker method work by filling the "transparent" background portions ...

The approach you you mention does sounds unorthodox, it is, however, the only way you can do it in ArcGIS. It is actually more efficient doing this inside ArcMap as you suggest as oppose to a 3rd party image editing software outside of ArcMap. The benefit is that you don't have to post-process your cartography in a another application and it is therefore ...

I'm assuming that you're trying to set the IColor as RGBA with the transparency in the colour... that's not how it works, when you create an IColor from RGBA only the RGB is set, the alpha is ignored... see IColor, the options are CMYK, Gray, HLS, HSV, RGB - none of these have Alpha. To get transparency on a layer you need to use the ILayerEffects Interface ...

As far as I know, there is no way to make text transparent in ArcMap. My suggestion for a workaround would be to export to PDF and then add the watermark using Adobe. That's what I do to add watermarks to my maps. The limitation of this would be that it requires Adobe Standard I believe. If you don't have Adobe Standard, here is a link with some other ...

Right-Click Layer Properties and select Transparency tab. You would have a default Row in the transparency pixel list. Delete that Row(Use Icon 3) If you just have to make the White part transparent, Create a new Row(Use Icon1). Enter 255,255,255 for Red,Green and white and Set 100 for percent transparent column. Click Apply and you are done. Some sample ...

It's not MapBox issue it is due to mistake in your code. OpenLayers.Layer.XYZ have three groups of parameters, so you need move isBase layer option into third group: var dark = new OpenLayers.Layer.XYZ( "Dark layer", ["http://a.tiles.mapbox.com/v3/billted98.map-cfmrdwtw/${z}/${x}/${y}.png"], { sphericalMercator: true, ...

Is combining the basemap and the contours in ArcMap and exporting from there not an option? If you haven't tried that, it's where I would start. Otherwise, I would export your contour lines using the PNG format - on the 'Format' tab of the "Export Map" dialog you can specify a color to be transparent or specify the background to be transparent. One of ...

You can definitely do as you mentioned make another shapefile to adjust the transparency http://resources.arcgis.com/en/help/main/10.1/index.html#//00s50000000z000000 However, what I do is: Create map and export as png/pdf/whatever format without creating a legend Create an additional map, turn off all the layers so only your legend is visible Open up ...

This is possible in QGIS using the print composer. You'll need to both: Remove the background color from the map item. This is done by unchecking the "background" option in the map item's properties. (The default is a white background) Set the page itself to a transparent style. This is done through the composition properties tab.

The following works in 10.2.1 and essentially turns the sketch hollow as suggested by Ian. As soon as you stop being in sketch mode it returns to your selected transparency. In the Editor toolbar go to Editor > Options and untick Use symbolized feature during editing.

If you are looking for the simple diagonal hatch method you mention, this can be achieved by symbolizing the home range polygons as unique categories. First use the '10% Simple hatch' symbol for all, and then customize the individual symbol patches. For each symbol, click on the Edit Symbol button where you can modify this line fill symbol's color, angle and ...

There is a 'Transparency' tab in Layer properties. You can adjust transparency for the whole raster or for specific values there.

Herein lies a misunderstanding: "...that is done separately for each band and not for a specific colour." "Each band" and "specific colour" are in fact the same thing. That is, it is the values in each band that, when combined together, make a specific colour. For example the RGB triplet 255,0,0 is the specific colour of pure red, comprised of band-red at ...

If you have an RGB map, you can use the pansharpening option in the symbology (RGB composite) of your RGB, selecting the Hillshade instead of a panchromatic image.

Is it possible to use an annotation feature class for the 'DRAFT' text, manually editing the text, and setting the transparency for the layer at 50%? This allows you to see the features under the text, and it is not necessary to export the document for use in another program.

You can only set the transparency if you symbolize say a point feature as a chart which in your case is pie chart. Please see the Symbology tab of your feature class. After this, you can set the transparency of your feature class from the Display tab and this will reflect on the pie charts.

The problem is not in the code, but on the image itself. The Geotiff has 3 bands, and the nodata value is set to 0 Band 1 Block=508x8 Type=Byte, ColorInterp=Red NoData Value=0Band 2 Block=508x8 Type=Byte, ColorInterp=Green NoData Value=0 Band 3 Block=508x8 Type=Byte, ColorInterp=Blue NoData Value=0 However inspecting the image in QGIS, it ...

Arcmap has the ability to save with transparent colour for those image formats that support a transparent colour: GIF and PNG, of these two the PNG (Portable Network Graphic) is the better format as it supports 24bit colour and transparency where GIF only has 8bit palette colour and transparency. To make the export transparent select in the export dialog ...

You can set the page background to transparent by creating a transparent symbol and setting the page background to use that symbol: transparent_fill = QgsFillSymbolV2.createSimple({ 'outline_style': 'no', 'style': 'no'}) c.setPageStyleSymbol( transparent_fill ) There's also a few other things wrong with your script: First, mapRenderer = ...

Have you tried '-t' flag? Its there in 6.4.1.

When you need your polygon symbol to be fully transparent, assign a null color to the fill symbol as others have suggested. Another way would be to set the Transparency of the fill color to 255, which has the same effect. You can also set your simple fill style to hollow. All this can be done for graphic elements so your drawings persist in the map. If you ...
