Stamp ToolboxStamps are the Albert's Paintbox clip art. We supply a lot and you can also make your own. An umbrella represents the active stamp – it doesn't mean all your stamps will be umbrellas. Acquiring stamps
Snap a stampThis is a simplified 'copy and paste' routine: the mouse is used to select an area which can then be used as a stamp. The selected area remains highlighted with a marquee and is made into a stamp. It is also copied to the clipboard so you can switch to another program and paste your selected area directly (useful if you've snapped the whole Canvas).
Snip a stampThis works in the same way as Snap a stamp, but is 'cut and paste': the selected area can be moved, leaving a white rectangle. Use the stampClick in the Canvas area to start using a stamp and there will be a ticking noise while the stamp is live. The stamp remains live until you click somewhere else on the Canvas, press enter, or choose another Toolbox. It then becomes fixed. If you press escape before fixing, the stamp on the Canvas is cancelled, although it is still saved in memory. A stamp that has been Snipped, Snapped or Loaded is always available, even if you've moved to a different Toolbox and back: a thumbnail view is shown to the right of the Stamp tools. If a stamp has not been Snipped, Snapped or Loaded, the Use the stamp button is greyed out. • If Use the stamp is inactive, the entire menu is not shown. Stamp backgrounds
Stamps are small pictures within a rectangular frame. Much of the time, the items you wish to use on a stamp aren't shaped like a simple rectangle. When our artist draws an item, he fills the background with a colour that he hasn't used in the picture. If you've selected Background off, Albert's Paintbox takes the colour found at the bottom left-hand corner and makes it invisible. This can have unexpected consequences. If you Snap or Snip a stamp from your picture and have the Background off, your stamp can develop holes because the colour in the bottom left-hand corner is repeated elsewhere in the stamp. To fix this, you need to change the colour of this spot – the Zoom in tool (Picture toolbox) is useful for getting in close to change just one pixel with the Freehand paintbrush. Alternatively, you could choose Background on and use the whole of the stamp. Stamps are Background off by default if you deactivate both buttons. Thin stamps have no backgrounds and behave like Thin paint: the picture shows through when you use them. This can be effective when building layers of stamps or paint. Load or Save Stamps
The Load a Stamp button takes you into the Stamps browser. To protect your system and to avoid confusion, users can't browse outside the stamps folders. The first item is the Clipboard, provided it holds a graphic. Any graphic item on the Clipboard created in another program can be used as a stamp. Remember that any stamp that is Snapped, Snipped or Loaded will also be copied to the Clipboard, replacing anything already there. Albert’s Paintbox is supplied with a number of stamps. If you wish to use clip art from any other source – Sherston, Clicker, symbol files and so on – you must copy the pictures into the proper place. Open the Configurations Editor (CONTROL + F2) and click Stamps folder. This will open the Stamps folder and any pictures you wish to use can be copied into a folder in this area. Stamps created by users are also visible in this browser although they are stored in the logged-on user’s directory: My Documents\Alberts Paintbox\My Stamps Stamps can’t be saved in any other area. They are saved here when you click Save the Stamp and are numbered automatically although the numbers are not used by the program. When a stamp is saved, a short animation is shown to show the process has occurred. To view the stamps from the Desktop, navigate to this folder; if you’re using XP or above, set the View to Thumbnails. Unwanted stamps can be deleted in the usual way. Multiple users with the same logon details will all have their stamps saved in this folder. Flip and Turn
It's bad enough that 99% of clip art isn't suitable, but when you do find something that will do it's often facing the wrong way. These utilities are designed to help. When there is an active stamp on the Canvas, you can Turn it clockwise in steps of 90 degrees, Flip left to right or Flip top to bottom. In combination, this gives 8 orientations for each stamp. Repeats
You may have noticed that the background on the Main Menu changes each time you go to it. Every time this screen is created, the program chooses a stamp at random from the Front Tiles folder in the Stamps area and tiles it to make a repeat pattern. If you press F8 you can cycle through all the designs, and you can load these stamps for your own use from the Front tiles folder. While the Main Menu design repeats a tile in a single orientation, the repeat patterns in the program are arranged in groups of four images.

Text ToolboxClicking on the Canvas creates a new text block that behaves in the same way as a Stamp: the text block is live until you decide to fix it by pressing enter or selecting another toolbox, or pressing escape to cancel. The text block reflects text that is typed into a box at the bottom of the screen – the cursor must be in this area or new type won't be shown. While the text block is live you can change any aspect. Paint
There are three font painting modes, identical to those found in the Paint Toolbox. Each can use solid colour or patterns:

File or Print ToolboxLoading or Saving opens a browser to the user's My Documents\Alberts Paintbox folder. You can browse to any other folder within My Documents, so users with a common login can each have their own folder. Files cannot be saved in any location outside My Documents or saved anywhere else.
Load a picturePictures can be in any graphic format recognised by Windows. If you wish to load any picture into Albert's Paintbox, it must be somewhere in the My Documents folder. Remember that photographs can be quite large. As with any graphics software, the bigger the picture, the slower the program will perform. Canvas sizeWhen Albert's Paintbox is opened, the default Canvas area is 650 pixels by 480 pixels, which is in the same proportions as your monitor (4:3). When you print from Albert's Paintbox, the Canvas is stretched or squeezed proportionally to fit the print layout you have chosen. If you open an existing file, the Canvas will take on the size of the picture and adjust the view to fit. You can specify the size of the canvas used in each Configuration in the Configurations editor. Choose a size from the Canvas drop-down menu. Teachers can create, edit or delete blank canvases by selecting Edit, found at the bottom of the list. This pops up a small window with the canvas editing functions. Any canvas that you create here will be available in the other Configurations, but will not replace the selected size. Naturally, if you delete a Canvas, it’s removed from all Configurations. Save the pictureNew pictures are saved in .BMP format by default. Pictures that have been loaded are automatically resaved in the format in which they were loaded, with the exception of .WMF files which are converted into a bitmap format. It is possible to save pictures in other formats. Click in the filename area at the top of the browsers and press the menu key. This will show a number of filetype options. Unlike most software, Albert's Paintbox never remembers filenames, just in case an important file gets overwritten accidentally. The only place files can be saved is in the My Documents folder. Print the pictureThis opens a dialog box giving the user the opportunity to click one of nine icons showing different locations on a page.
Click the Turn page icon to change the page from landscape to portrait and back. The picture will be scaled proportionally to fit the location chosen. With a little ingenuity, it's possible to print four pictures on one page. In the classroom

Picture ToolboxNo matter how large the picture that's loaded, Albert's Paintbox always gives the picture best fit in the Canvas area. Even if you're not in the Picture Toolbox, it's always possible to zoom in and out of a picture by holding down the shift key and scrolling with the mouse wheel. You can also hold down the shift key and drag the picture round with the mouse when zoomed in.
For younger children – and for those who don't have a mouse wheel – the Zoom in and Zoom out buttons perform the same task. When you are zoomed in as far as you can go with the smallest Brush you can make, it's possible to edit individual pixels. Zoomed in pictures can be dragged around with the mouse when you are in the Picture Toolbox. Flip and Turn
Sometime pictures look better when they're facing the other way. There's that story of the piece of modern abstract painting that was displayed in the Tate Gallery upside down for six years before anyone noticed. These buttons work on the whole picture to let you Turn it clockwise in steps of 90 degrees, Flip left to right or Flip top to bottom. Symmetry
All Painting (except Fill), Text and Stamp tools work with symmetry turned on: Horizontal mirror, Vertical mirror and Vertical and horizontal mirrors. Click No symmetry to turn symmetries off. The lines of symmetry are applied to the entire Canvas, even when zoomed into an area where the lines are not visible. In the classroom
Colours and PatternsColour/Pattern pots are hexagonal. Above them are the Colour picker, the Colour/Pattern maker, the Use colours button and the Use patterns button. The current colour or pattern is highlighted with a white frame. The Colours/Patterns can't be turned off in the Configurations editor, but you can choose to use only Paint or Patterns or both. Use Colours, Use PatternsThe colour pots show either colours or patterns. Click these buttons to switch between the two. Colour PickerThe Colour Picker can be used to copy any colour in the picture. Picked colours replace the colour in the highlighted Colour pot. Colour/Pattern makerThis tool changes function to match the current colour/pattern mode. Colour makerThere are two further means of changing the highlighted colour. The default is a simple colour picker:
At the top of the panel is a rainbow selection of colours and grey. In the centre of the panel is a hexagon showing the Old colour and beneath that another hexagon showing the New colour that will replace the highlighted colour when you click the OK tick button. To the left and right of this hexagon are four darker and four lighter shades of this colour. Click any hexagon to choose a new colour, or click the Cancel cross to keep the old colour. If you have selected Advanced colour mixer in the Configurations editor, you can actively create colours rather than passively picking.
Colour mixing in Albert's Paintbox is based on the additive colour system (the mixing of light) used by televisions and monitors, rather than subtractive colours (the mixing of pigments) used when painting or printing. All the 16 million colours that computer systems can show can be created (even if human eyes can't tell the difference between a lot of them) and they are all made from different mixes of red, green and blue (RGB). The Advanced colour mixer is easier to use than it looks: it needs to be played with to get the best out of it. Seven clickable base colours are offered as starting points: the red, green, blue primary colours; the cyan, yellow, magenta secondary colours; and grey. The Old colour is shown in a hexagon beneath these, and the New colour hexagon is underneath that. In the left-hand side of the dialog box are the Red slider, the Green slider, the Blue slider (RGB) and the Brightness slider. When the red, green and blue sliders are at their maximum, you make white, and black when they are at minimum. Each slider also shows a gradient of all the possible colours that can be made by adjusting that slider while the other two remain fixed; each pointer indicates the same colour. Pick the colour you want from one of the gradient bars by clicking on it or by moving that slider to point to it. All 16,777,216 colours can be made using the RGB sliders, but it is difficult making a colour lighter or darker as it involves adjusting more than one slider. To make things easier, the Brightness slider can be used to adjust the tint of the colour defined by the RGB sliders. Moving the Brightness slider will, of course, adjust the RGB sliders. Do not be tempted to describe the Brightness slider as 'Adding white' when lightening a colour. The Brightness slider is just a convenient way of simultaneously adding or subtracting RGB values. Pattern MakerAll the patterns are based on an 8 x 8 grid and an enlarged version is shown in the box. The colours are on the left, repeated from the Workspace. The selected colour can be replaced with any colour in the grid by using the Colour picker. This is a temporary change and you will not alter the corresponding colour in the Workspace.
Pick a colour and click in a square on the grid. The Old pattern is in the hexagon on the left and your changes are shown on the right. You have up to twenty Undo steps, but if that isn't enough, click the cross to Cancel. Resetting Colours and PatternsColours and patterns are edited at user level: all changes apply for all Configurations, but only for the logged-on user. Edited colours and patterns are stored in: My Documents\Albert's Paintbox\Resources\_Palette. In this folder, patterns are numbered from 0 to 15, colours are stored in files numbered 16 to 31.

Undo, Redo and Bin
Up to 10 Redo steps can be set for each Configuration. The Bin clears the workspace, but a picture can be retrieved by clicking Undo. Additional featuresSome features of Albert's Paintbox are not controlled from the Workspace but are set in the Configurations editor. Generally, these items are on or off. Sound effectsMost tools have their own sound effects when they are used, ideal for children who need some feedback or a cause-and-effect environment. But even the child isolated from the rest of the world with headphones can find them tiresome. Rollover text hintsWith this set on, the name of the button is put on the screen after a short delay. Font, size and weight can be adjusted in the file: Alberts Paintbox\Resources\Language\English\Font.txt
If you change the font, you may need to experiment with the supporting numbers to get a good result. Rollover speech hintsWith this set on, the name of the button is spoken after a short delay. Don't fill blackFor children with poor motor control who are practising filling in area with colour, accidentally filling the outline can have devastating consequences. With this facility on, black cannot be changed. Advanced colour mixerThe Advanced colour mixer is the means of changing colour when this is set to be on. When off, the simple colour picker is used. ScrollbarsWith this feature on, standard scrollbars can be used to control the Canvas view when zoomed in. It's always possible to zoom in and out of a picture by holding down the shift key and scrolling with the mouse wheel. You can also hold down the shift key and drag the picture round with the mouse when zoomed in. UndoYou can set up to 10 levels of Undo.
