Raster image resolution

[SCTINFORMATICA]

I need to read the resolution in X and Y of an AcDbRasterImage inserted into a drawing using ObjectARX

I've tryed AcDbRasterImage and AcDbRasterImageDef but I can't find out the information I need.

Can anyone help?

Thanks

Hi,

You want size in pixels? From documentation:

AcDbRasterImage::imageSize

Returns the raw image size in pixels. (The image size is also available directly from the AcDbRasterImageDef object.)

Does it help you?

Thanks Jonathan,

  I've seen the imagesize function but I need to extract the DPI of the image.

Imagesize reports that the image is xxx pixels high and yyy pixels width but I need to know

how many DPI this pixels are.

Thanks

Flavio

Have you looked at the AcDbRasterImage class in the ObjectARX reference? I see AcDbRasterImage::imageWidth() and AcDbRasterImage::imageHeight(), which appear to be what you're looking for.
