Invalid image size in PictureMarkerSymbol?

BorisPelakh — Fri, 07 Jan 2011 18:21:44 GMT

I am placing images on a custom layer, and create the PictureMarkerSymbol w/ the following:

PictureMarkerSymbol ps = new PictureMarkerSymbol();
ps.createMarkerSymbolFormFile(esriIPictureType.esriIPictureBitmap, imageLocation);
ps.setBitmapTransparancyColor(color);

I then try to obtain the size of the image from

ps.getSize()

, and I always get 8, even if the size is 16x16 or 32x32. This messes up the scaling code I use during rendering. I also tried

ps.getPicture().getHeight()/getWidth()

, and that gives me completely ridiculous values (> 400).

I previously used

createDynamicGlyphFromFile()

when the rendering used dynamic layers, and it gave me accurate sizes via

glyph.queryDimensions()

. What am I doing wrong with PictureMarkerSymbol?

Also, with dynamic glyph I could apply a color map to the image using IDynamicSymbolProperties.setColor() to apply a color mask to an image, so I could use a single white image and apply any color I wanted to it. This does not appear to work with PictureMarkerSymbol, even though there is a setColor method.
