Hi all,

I am experiencing a problem when I use one of these tools, but it is a strange problem and I find some difficulties in explaining it. Nevertheless, let me try....

If I select the paintbrush and I draw a random curve on my picture, every now and then some of the pixels of the curve are "displaced" either horizontally or vertically. The effect is more visible with a not so small brush (either soft or hard) and when the image is zoomed at least at 1:1

By itself this is quite annoying but it is not all: the effect is, in fact, an illusion. The line, in reality, is well drawn and I can realize this by the fact that if I zoom in and then out the effect disappears!!!

Did anybody experienced the same thing? What is the cause? How can I correct this?

Thank you for your help

Fabio

PS: I also have a problem in compiling gimp 1.2.5 under mandrake 9.0: all needed devels packages are installed, ./configure says everything is ok and compilations starts ok and goes on for 10-15 minutes, then I get an error.
But, for this, maybe it is better if I include in another post the last few lines of compilation output...

Hi,

This is a known bug which is fixed in later 1.3 releases and if I remember correctly the fix has been backmerged to version 1.2.5 as well.

You remember well: in 1.2.5 it is fixed. So, now then I come to the other problem: compilation of 1.2.5... What follows at the end of the message is the error I get when compiling: does it give anyone a clue on what is wrong? I want to stress that ./configure gives no errors and, moreover, compilation was fine on another desktop on which I have the same distribution (mdk 9.0) with _exactly_ the same *devel*.rpm packages.

If I will succeed in compiling, then the only wish about paintbrush would be to see its size, but I know I am not the only one wishing this and we have still to wait a little... :-(

Since I am talking about paintbrush, I have another question: in its "Tool options" box, there is a voice: Pressure Sensitivity
with four choices:
Opacity Hardness Size Color
Well, I must admit that I can't see any difference in the behavior of the paintbrush whichever mode I choose.
I also looked on the gimp manual and on "grokking the gimp", but I couldn't find any explanation about this.

Thank you very much

Fabio
