The control bar situated to the left of iconview has a cursor, rectangular selection, textual input, pencil, brush, eraser, bucket and gradient tool.
The pencil control is always 1x1 pixel in size, that is to paint pixels of a larger radius, the brush tool must be selected. The size of the brush or the eraser is determined by the slider that appears on the top toolbar whenever either of these control types are selected.
The bucket fill control type can be used to quickly and accurate fill a region of pixels which are equal to and connected to the origin pixel selected when the tool is initialised. The value of the fill is equal to that of the primary colour selected.
In this instance to the left, the primary colour is light red and the secondary colour is black. Historical colour values appear in the palette and they may be quickly recovered by clicking on each.
Which will in turn hot swap the historical colour back as the primary colour. Primary and secondary colours can be changed by clicking on each and selecting a new hue set from the dialog which appears.
When icons are saved into the ico file format. If the save is a fresh file then Iconmake if permitted will export multiple variants of the same icon which is typical in a ico file format. For example a 48x48 will be saved as a 48x48 and will be accompanied with a 32x32 and 16x16 variant to support ico readers which use distinct variants to support multiple resolutions.
The scaling option can be toggled via the configuration module within NPro Power Tools in addition to how the brush control type manipulates neighboring pixels.
