Hello,
I have two questions about the IEVolution .NET (v8.0.0.0) layers.
1. Is it possible to mirror text from right to left or left to right for IETextLayer?
2. When creating IETextLayer, FillColor and FillColor2 are transparent by default, if I change it to a different color, how can I change it to transparent afterwards? Color.Transparent does not work in this case.
Regards,
Deeron |

Hi Deeron
1. Sorry, IELayer.Flip is not available in IEvolution. You will need to convert it to an image layer, then flip the image
2. You should be able to set the FillColor to SysNone ($1FFFFFFF or 536870911).

Hello,
"2. You should be able to set the FillColor to SysNone ($1FFFFFFF or 536870911)."
This is interesting.
This doesn't work for me, the background color will be white, it won't be transparent whatever value I give to Alpha (0-255).
I tried it like this:
IETextLayer iETextLayer = (IETextLayer)ieViewer1.Image.CurrentLayer;
iETextLayer.FillColor = Color.FromArgb(31,255,255,255); //$1FFFFFFF
iETextLayer.FillColor2 = Color.FromArgb(31, 255, 255, 255); //$1FFFFFFF
Unfortunately, this does not work for the IEShape layer either. :(
Regards,

Hi Deeron
What is the default value of iETextLayer.FillColor, i.e. before you set it to a color?

Hello,
"What is the default value of iETextLayer.FillColor, i.e. before you set it to a color?"
FFFFFFFF (255, 255, 255, 255) is the default value for FillColor and FillColor2 and the iETextLayer background is visually transparent.
I honestly don't understand how this default value ARGB Alpha color (FF) can be transparent.
The ARGB Alpha value (255 dec, FF hex) should be completely opaque and the (0 dec, 00 hex) value should be completely transparent, right?
Regards,
Deeron |

Hi Deeron
Because of its Delphi underpinnings, IEvolution does not make use of the A channel of an ARGB value. Does setting the color to FFFFFFFF revert it to transparent?

Unfortunately, does not reverts, the background will be white. :(
If IEvolution doesn't use the Alpha channel of the ARGB value, how is it possible set the transparent background for the iETextLayer (most likely for the other layers as well) after changing the background color?

Hi Deeron
Unfortunately this looks to be an issue in IEvolution. We'll need to address that in the next update.

Hi Deeron
This is fixed in the current beta, which will be released shortly.
You can now remove the background with
myTextLayer.FillColor = Color.Empty;
The same works for FillColor2.
IELayer.FillOpacity will be used to regulate background transparency.
