Flattening bug: Text effects visible border when placed on radial gradient.


Recommended Posts

If you place text with a drop shadow on an object with a radial gradient fill, you will see a border around the shadow of the text after the flattened export (standard X1a preset).

It looks correct in the document and in the export preview.

This only occurs with radial gradients (as far as I can see).

I am attaching documents. If someone could test it, I would be grateful!

Hi @PeterB.,

I believe the issue is caused by the radial gradient being 'scaled', effectively you have an elliptical gradient rather than a radial gradient... If you convert it back to radial by double-clicking the upper scale node it will 'visually' appear radial rather than elliptical and it will export correctly...

I think but can't be 100% sure that this is a known issue with gradient scaling...

@Hangman Interesting, now that you mention it, I notice that if I assign a radial gradient to any rectangle, it doesn't insert a radial gradient but an elliptical one. @NathanCThe radial shouldn't actually have two handles, should it? As soon as I double-click on the dotted handle, it disappears and doesn't appear again. Is there perhaps a bug in the radial gradient function?

Edit: It only occurs when using the fill option in the toolbar. If you first draw a gradient with the gradient tool and then change it to radial with the fill option, the behavior does not occur.

Hi @PeterB.,

It shouldn't do so regardless of the Picture Frame Property setting... though it will do so if you Scale or Transform the picture frame after applying the gradient...

If you transform the object (Re-size, Shear etc.) with a radial gradient applied to it the radial gradient will automatically re-apply itself to fit the object's new scaled proportions, and will show a second dotted axis handle to indicate the transformation, see screenshots below.

1. Standard rectangle shape with a Radial Gradient Applied

2. -40 deg Shear added to the object, radial gradient is applied with Stretched/Transformed proportions.

3. Re-applied 'Radial' gradient to the object, intelligent scaling has now been lost.
