add single image to queue

automatically update the preview if the calculation took only a certain amount of time in milliseconds, e.g. 500 (0.5 seconds) this Slot is for parame

uses a similar algorithm like "soft light" in PS, see http://www.michael-kreil.de/algorithmen/photoshop-layer-blending-equations/index.php

the displacement map is generated with the specularmapGenerator (similar controls and output needed)

Used to scale down the input image if a value less than 100 is set in spinBox_normalmapSize. We have to make sure size is at least 1

change the path the queue exports the maps to

connects gui buttons with Slots in this class

display the last calculation time in the statusbar

displays single color channels of the image (handled by an intensitymap)

fits the preview into the graphicsView

generate a message that shows the elapsed time of a calculation process example output: "calculated normalmap (1.542 seconds)"

load the image specified in the url

load images using the file dialog

transform -1..1 to 0..255

calculates the size preview text (e.g. "1024 x 1024 px")

overloaded version of preview that chooses the map to preview automatically

read window size, position etc. from registry

resets zoom to 1:1

save maps using the file dialog
