Moving the window while a user is holding a button down is quite problematic

Can't you just move the window away from the insertion point as soon as the window opens? Maybe even leave the insertion point cursor in its original position? Making the window transparent would help if there were several lines of text, but the most important thing is to see at least the first line. Moving the window down and right by 100 pixels would be enough in many cases, though if the cursor is already at the right or bottom of the IV window so that the text window won't fit on the desktop, then it would need to move down and left, or up and right, up and left instead by a 100 pixels from the bottom corner of the insert text dialogue.

I wrote down an algorithm that works this way:

• it calculates a "forbidden area" where the dialog must not be in this way:
  

  	RECT forbiddenRect;
  	forbiddenRect.left=insertPoint.x-200;
  	forbiddenRect.right=insertPoint.x+200;
  	forbiddenRect.top=insertPoint.y-60;
  	forbiddenRect.bottom=insertPoint.y+40;

  ;
• then it checks if the window rectangle intersects the forbidden area; if it doesn't, does nothing;
• otherwise, it searches a good position for the window, first trying to put it under the forbidden area, then over, then on its right, then on its left; if in all these cases the window gets out of the screen, it's left where it is; otherwise it is moved to the first good position.

Do you think it's OK or should I change something (especially the size of the "forbidden area")?

I wonder if you need a bigger gap above the insertion point for large font sizes? The first line of text might be hidden by the dialogue if it is above the insertion point.

I'm not sure if you need to move the dialogue horizontally at all, since if the user can see the first line of text he/she can see if the insertion point is in the right place. The horizontal position seems to work best for left, right, and centre aligned if the dialogue is centred horizontally on the insertion point.

Moving the dialogue depending on the text alignment might be complex as the text alignment can be changed after the dialogue is opened.

version 59 is great

MItaly
many thanks for version 59

I choir with Al.
This is a job with nice progression. And the addition of tolerance is a big step.

Cloning Screen Capture

Here it is, an image of the two cursors and a cloned spot. The cursors look the same whether the clone tool works or not; I presume this is how they are supposed to look. I understand now how the ghost cursor functions-- quite clever-- but that has no bearing on my recurrent problem, at least none that I can figure out.

I still wonder, is there a memory cap on this function: when so much RAM is utilized in alterations, the tool works slowly or not at all? Is that possible? The trouble never occurs at first, only after considerable use on an image.

[matera]

A couple of questions. How much RAM do you have, how much is usually free, and how much difference does cloning make? You could check that out easily enough with a resource meter, some small free ones can be downloaded here and there. What else is using a lot of graphics resources, are you into animated wallpaper (LOL just kiddin' there)? What version of Windows and how much other background activity, processor speed, lots of factors to consider if that is causing the difficulties.

What I see in the attached picture is an area being cloned onto an almost identical area. It doesn't tell me much.

[Sam_Zen]

The attachment tells me that it is a very zoomed-in segment of a far more bigger picture, where the function is executed.
This means a lot of mem-refreshment, so no wonder it takes some time.

[MItaly]

But in the picture attached the cloned circle on the green part has been done previously or you are showing that IP clones in the wrong place?
For the memory thing, I'm working on it.

[Vorchek]

Nor do I derive much information from the picture. Based on one comment, I'd gotten the notion that the ghost cursor took on the appearance of the spot being cloned from. I presume that is not true. Otherwise, I suppose the parts of the picture look the way they should.

I am now fairly certain that I do not have a RAM problem. I have 2GB of RAM on my XP, Duo Core 2 machine; 1.4 is usually free, dropping to 1.2 while fussing with pictures. I do not do anything else graphics intensive.

[Vorchek]

"The attachment tells me that it is a very zoomed-in segment of a far more bigger picture"-- Correct. "This means a lot of mem-refreshment, so no wonder it takes some time."-- When the cloning works, it does so instantaneously. When it doesn't, it isn't just slow; nothing happens, no matter how long I wait.

[MItaly]

Based on one comment, I'd gotten the notion that the ghost cursor took on the appearance of the spot being cloned from. I presume that is not true. Otherwise, I suppose the parts of the picture look the way they should.

The ghost cursor with the X in the middle should always be on the portion of image being cloned; the cursor with the + is always on the destination of the cloning.

When the cloning works, it does so instantaneously. When it doesn't, it isn't just slow; nothing happens, no matter how long I wait.

Does IV hang when the clone tool don't work?

comparison between drawing with IrfanPaint and PhotoFiltre

I have compared the method "drawing arrows and/or lines" in IrfanPaint with PhotoFiltre!

And I've determined some differences!
The quality of drawn lines and arrows is better with PhotoFiltre!
Drawn with IrfanPaint is not so fine! Not correct lines!
You can see all pixels individual! (Similarly like gradate stairs!)

see:


Is it possible to improve this method in IrfanPaint?

[MItaly]

This is because IrfanPaint still doesn't support antialiasing, but it's not a simple feature to implement at the current state of work.

"Does IV hang when the clone tool don't work?"

No.
