Dear Fop-developers, continuing on the improvements of support for image plugins in Fop (particularly MathML plugin), there are two more things that need to be addressed. I am quoting from a previous mail to jeuclid-devel:

This would be great. Unfortunately I have no idea how it would be done in detail. >> - Baseline offsets > Should be doable. I have found a spot where this information would be placeable: FopImage.ImageInfo. Unfortunately, changing this class could probably mean that all plugins will have to be recompiled. Here's my idea: - add a new attribute baselineOffset, default to 0 AbstractGraphics would provide a hook "getAdditionalAlignmentAdjust", and getAlignmentAdjust would use this value; InstreamForeignObject could then use "getAdditionalAlignmentAdjust", to provide the additional offset needed for inline objects. So would it be feasible to change ImageInfo, possibly introducing an API change? And if so, the current API uses fixed-point sizes only (e.g. all sizes can only be complete pixels). IMO this should be changed to support float or double values, as some vector graphics have a higher resolution.
