Readme-file for ArtPaint 1.3

1. Introduction
This file describes what improvements ArtPaint has received from version 1.2.3 to 1.3. ArtPaint 1.3 is a minor update that fixes a few bugs and adds a couple of new features.

2. New features
	-	Ability to rotate the canvas by 90° either clockwise or counter-clockwise. 
		This is especially good for digital photos that are taken in portrait orientation.
		Look in the canvas menu for new items for doing this.

	-	Tool selection by hotkeys. The painting tool can be selected by pressing a key 
		on keyboard while the paint window is active. The keys are defined as follows:

			a		Airbrush
			b		Brush
			c		Color selector
			e		Eraser
			f		Free line
			h		Hairy brush
			i		fIll
			l		Line
			n		traNsparency
			p		elliPse
			r		Rectangle
			s		Selector
			t		Text
			u		blUr

	-	Pressing down alt activates the color selector tool for the duration that the alt
		is held down. After the alt is released, the tool that was previously active is 
		again activated.

	-	Pressing down control key while using the line tool restricts the line angle to
		mulriples 45 degrees.

	-	Selecting a brush from the brush window automatically activates the brush tool

	-	The pop-up-menu in the layer-window no longer requires the right mouse-button.

	-	Pressing TAB hides or shows all of the floater windows.

3. New add ons
This release includes three new add-ons as compared the previous version. These add-ons were released  a while back as a separate package. Now they are included with the program (note that they are currently available only on x86. PowerPC versions of the add-ons wil be released if there is enough demand for them). Short documantation for those add-ons follows here:

Gaussian Blur:

	This is a filter that blurs the image. It is quite similar to the included blur filter, but
	it allows for more precise control of the blur and the resulting blur will be somewhat
	better looking than the other blur filter. To use the filter adjust the blur amount with
	the slider. When you let go of the slider the image is calculated. The calculation may
	take some time, and the bigger the blur size is, the slower the calculation is.


Sharpness:

	This filter allows you to adjust the sharpness of the image. It actually works by
	increasing contrast near the edges. There are two sliders to use. The top slider
	adjust how much sharpening should be applied. It reflects the change on the image
	as you move it. The lower slider affects how far away from the edges the effect
	will affect. This slider takes effect when you release it and then it will take some 
	time to calculate the new image.


Painter:
	
	This is the most interesting of the new add-ons and it is an effect that allows you to
	turn the image into something that looks a bit like a painting. This is still in development 
	stages and the next version of ArtPaint will have an improved version of this. There are
	numerous controls to play with and you may freely try them to find out good settings. As 
	the effect takes very long time to calculate, it only displays preview for a small area of the
	image at a time. To change the preview area click on the image and move the mouse. One
	that should be mentioned is that this uses various sized brushes and the brush-size determines
	the radius of the biggest brush. The brush count determines how many different sized brushes
	will be used and brush ratio determines how much the next brush is smaller than the previous.



4. Bug fixes
This release includes numerous bug fixes, some of which were crashing bugs.
