Text shadow

[Roder51]

I use xnview a lot but lately I've noticed when I embed say a white text on a green backgroud it creates a shadow of a kind. Has anyone else had this problem and if so how did you fix it.

With 'Add text'?

With 'Add text'?

Yes Pierre

[xnview]

could you post a screenshot?

[Roder51]

Notice the shadow of small white dots around the text. I used image>add text to do it.

[xnview]

could you send me original picture?

Aren't those compression artifacts caused by the sharp contrast between pure blue and pure white?

An even higher level of compression might help, or saving as a .png might be better...

Note: When there is a sharp colour transition, having resampling when zooming enabled can also produce artifacts, even on a .png which preserves the pure colours.

I have no idea what you're saying Cday. Here is another picture. An imported screenshot from Microsoft word.
Now that I've imported the picture into PICASA there don't seem to be a lot of difference whether I write on
the picture in Word or XNVIEW. Would love to know what's going wrong though. I will try uninstalling
and re installing the program. The 6th and 7th lines are the same size fonts as above. I dunno why it looks to be bigger.

It's the problem of JPEG compression, try to use PNG for example

Yes, the "shadow" are definetely compression artecfacts, see the explanation and examples on Wikipedia. Using a lossless image format like PNG will avoid the problem.
