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 ...

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 ...

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 ...

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 ...

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 ...

The easiest way is to edit the aplha for the fill

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 ...

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 ...

I did not understand what specific question you have, since you only described your problem. I m quite new to GIS but I think I may be able to help. Can you please form a clear question that requires a clear answer? Note* I know that this is rather a comment than an answer, but I m currently still unable to comment. Edit: Ok; If I get you right you want to ...

Here is what I did: Created big_aoi featureclass Created small_aoi featureclass (the real area of interest in the middle) Unioned the two (but Erase will work better as artwork21 points out), got big_aoi_Union featureclass Deleted the inner polygon from the union to get the donut Set big_aoi_Union to dark grey with 50% transparency And I got: This ...

You should use two different STYLE blocks, one for the fill and one for the stroke: CLASS STYLE OUTLINECOLOR r g b #stroke WIDTH 3 END STYLE COLOR r g b #fill OPACITY 50 END END Ordering is important, you'll get different visual results if you swap the order of the STYLE blocks.

Assuming you're trying to use it within a GIS-system, QGis does the trick. It's a free GIS-system, and you can set transparancy layer-based, toggle layers on and off, switch around the order, ... Whereas - to the best of my knowledge - Arcview or MapInfo's Proviewer do not offer the option to combine layers. That said, transparancy and opacity are not ...

There is a Knowledge Base document entitled FAQ: What is the best format to use when inserting logos into a map document while maintaining transparency? which says: Logos are usually designed in a vector illustration package such as Adobe Illustrator, and then exported to a pixel-based format. However, exporting the logo as EMF will maintain the ...

You can enforce real nodata on the file using GDAL translate utility, look in your QGIS install location bin\ folder. GDAL_Translate -of GTIFF -a_nodata value InTiff OutTiff Substitute your own value for value. NoData does not have to be the highest or lowest value in the file you can set it to any value. Only one value is supported though so if you have ...

This is more of a strategy than a proven answer. This assumes that the black triangles are part of a rectified image. Can you save the image file in a format that supports transparency such as png format. That would enable you to set the white to transparent as well as manually select and delete the black triangles using an image editor. Deleted parts ...

maybe this will work for you: Insert or draw the graphic in Data View Drawing toolbar: covert graphics to features (delete graphics after conversion) Feature is added to TOC; then set transparency % in layer properties please note: In order for the text box to work feature with transparency I had to drawing toolbar > New Annotation Group > Activate ...

@baens you're right that it's in Symbology > Advanced > Transparency. @Mapperz is right that it's in 10.1, but not in 10.0, but not about the location of dialog. This is the dialog that comes up. Edit: Just looked again at 10.0. It's there, but I only see it for polygons -- not points or lines -- may be what's causing the confusion.

I just tried adding two shapefiles (one polygon over the top of another which was lines) to ArcMap 10.0 SP5. The polygons were displayed using a solid fill. I then adjusted the transparency of the polygon layer using both the Layer Properties and Effects toolbar methods described here. In both cases the symbol used for the polygons became transparent in ...

Open the Layer Properties of the image, go to Colormap, set the colorinterpolation to 'exact', delete the white entry (0.0000) and you are done.

OK, I found the solution (work around). I realized, that I was working with an old version of gdalwarp, where the -cut_to_cropline option was not supported! Anyway I got an upgrade done and it seem to accept this option. I still got the "Cannot compute bounding box of cutline" error, that obviously has something to do with my cutline shape file. I removed ...

Try the combination of options from the link below. It worked for me and shows the correct transparency in QGIS. You can grab the gralwarp command-line from there or try using the UI. Clip a Raster in an Irregular Shape using QGIS
