Non-Horizontal Text Labels Poor in GD and Mince in AGG

[crispinatime]

Hi,

Please see attached screen grabs for text rendering issues.

Both the AGG and GD images were generated from the same server and data just with a server stop, editing the serverconfig.ini and restarting to ensure a level playing field.

Two main items: GD - Vertical line labelling - the red line is the geometry and the label obviously is falling off the bottom of the line. Possibly one of those unhandled special cases where the delta-X in the line is zero?

AGG - All the words of the text string have been stacked on top of each other!!! The angled line also renders poorly compared to GD.

Pictures are nice, but can you also attach the layer definition which gives this behavior? That would greatly help us to track down the problem.

Thanks!

Hi - I understand... please see below...

I have also seen labelling issues on horizontal lines where the first word of a label string appears above the line (correctly) but with a short line the second word in the string is rendered upsidedown and in reverse along the bottom of the line... which I can understand but think it should be rendered in the same direction as the first word.

I tried your style on a simple SDF data set that had some horizontal and vertical lines, and the labels looked ok. This was using the current open source code.

What version(s) of MapGuide are you seeing the problems with?

Since this may be data-dependent, would you be able to create a small package?

[crispinatime]

Hi, - I always assume that FDO makes things data independant but I will try and export the source data from Oracle into SDF to recreate as a package. Off this week so there will be a delay - thanks for trying to recreate though...

Please re-test against 2.1 and let us know - and send test case - if this is still an issue, or close if has been fixed. Will close this ticket if no response by next ticket cleanup cycle.
