- About Hatchback
- ===============
-
- Hatchback is a clever utility which allows the colours of objects in Draw
- files, compressed Draw files, and Poster files to be replaced with patterned
- fills. Any objects, with the exception of single lines of text, text areas
- and sprites, may be processed. Hatchback treats all objects as individual
- objects so group objects do not have to be ungrouped in order to be edited.
- Objects with no fill colour may also be filled.
-
- Although designed primarily to allow files to be prepared for mono printing,
- Hatchback does allow you to use colours instead of the default black on
- white. In addition to providing palettes for 16 colour and 256 colour modes,
- Hatchback also provides 256 shades of grey and a RGB colour cube which
- provides a vast range of colours. You may choose colours from the palettes
- or from colours which are already in use in a picture. They may, therefore,
- be copied from one picture to another.
-
- Edited files may be saved as:
- a) Draw files
- b) Poster files
- c) Compressed Draw files which may be loaded into Poster, Chameleon or
- Vector.
-
- The Undo and Redo facilities allow changes to be cancelled and then restored.
-
- Zoom and Magnification facilities allow accurate editing of small areas.
-
-
- Loading Files
- =============
-
- Any Draw file, Poster file or compressed Draw file may be loaded into
- Hatchback by dragging its icon onto the Hatchback icon on the icon bar. If
- you wish to load files into Hatchback by double-clicking on them you will
- need to change the default configuration using the Choices option on the
- icon bar menu.
-
-
- Using Hatchback
- ===============
-
- Load "example 1" into Hatchback.
- Click on the top right icon and then click on one of the objects in the
- picture.
-
-
- Using the other tools you can fill the remaining objects with different
- patterns. You can then change any of the filled objects by applying a
- different pattern. One of the objects has no fill colour. Click on its
- outline to apply a pattern.
-
- The tool at the top of the middle column of icons is the solid fill tool.
- Instead of providing a pattern it allows you to change the colour of an
- object.
-
-
- The Tool Box
- ============
-
- The tool box is divided into four sections:
- 1. Target area: (left hand column) defines which objects will be affected by
- operations.
- 2. Patterns: provides a choice of patterns for filling objects.
- 3. Colour box: shows the currently selected colours.
- 4. Magnifier: shows an enlarged view of the area beneath the pointer (when
- the pointer is over the picture window). The circle at the centre marks the
- position of the tip of the pointer. For accuracy, you can use the arrow keys
- to move the pointer one pixel at a time.
-
-
- Target area (left hand column)
- ===========
-
- This defines the area which will be affected by the editing operations.
- There are five types of area:
-
- LOCAL: only the object beneath the pointer will be changed.
- GLOBAL: all objects having the same colour as the object beneath the pointer
- will be changed.
-
- The other three target areas require a box to be dragged into position and
- sized as required.
-
- WITHIN BOX: changes will be applied globally to objects which are entirely
- enclosed by the box.
- BENEATH BOX: changes will be applied globally to objects which are either
- within the box or overlapping the edges of the box.
- NOT WITHIN BOX: changes will be applied globally to objects which are NOT
- entirely enclosed by the box.
-
- A new box can be created by pressing Select and dragging the pointer. The
- box may be moved by dragging the top left corner, or its size may be changed
- by dragging the bottom right corner.
-
-
- Pattern parameters
- ==================
-
- Pressing menu over any of the pattern icons opens a box which allows you to
- set the parameters for that pattern.
-
- There are three parameters:
-
- ANGLE: The pattern is rotated to the specified angle. Clicking on a value
- with Adjust makes the value negative.
- DENSITY: The ratio of foreground to background colour is controlled by the
- density value. The higher the value the darker the pattern will be.
- FREQUENCY: This controls the size of the pattern. The value specifies the
- number of times the pattern is repeated per centimetre, inch or point. The
- higher the value the smaller the pattern.
-
- Warning! High frequencies may require lengthy processing times (depending
- upon the complexity of the object) and will result in larger files. A fill
- operation can be abandoned by pressing Escape.
-
- A pattern which has already been used to fill an object can be ‘picked up’
- (and made the default pattern) by double-clicking on the object with Adjust.
- This allows you to copy a pattern from one object to another (even if they
- are in different windows) and means that you can create files to store
- patterns for specific purposes.
-
-
- Colour box
- ==========
-
- Two colours are shown in the current colours box in the toolbox. They are
- represented by a cross on a background. By default, the foreground colour is
- black and the background colour is white.
-
- To change the foreground colour click on the cross and to change the
- background colour click on the background. (If the solid fill tool is
- selected, only the foreground colour is shown.)
-
- A colour can be selected by:
-
- clicking on one of the 16 colours,
- entering or editing the RGB values,
- adjusting the RGB sliders, or
- using the up and down RGB arrows.
-
- You can also select foreground and background colours from an object. Click
- on any object with Adjust and the colour beneath the pointer will become the
- currently selected colour. This allows you to copy the colours from one
- object to another or from one Draw file to another.
-
- If you wish to use the 256 colour palette select 256 colour palette from the
- colour box. You will find it more convenient to change the Desktop mode to
- one which supports 256 colours.
-
- The RGB colour cube provides subtle changes of colour. The x and y axes of
- the matrix provide the Green and Blue components while the vertical slider
- allows the Red component to be changed.
-
-
- The Hatchback Main Menu
- =======================
-
- The menu is opened by pressing Menu while the pointer is over the Hatchback
- window.
-
-
- Tools
- =====
-
- Lock (F7)
-
- When Lock is selected you cannot make any changes to the picture. This
- facility is useful when you have loaded a file in order to copy its patterns
- as it prevents you from accidentally making changes.
-
-
- Full View (F5) and Zoom
-
- When Full view is selected, the complete drawing is rescaled to fit the
- window whenever the size of the window is changed. If you click on the
- Toggle size icon the window will be enlarged to fill the screen. Clicking on
- it again will reduce the window to its original size. Each time the drawing
- is rescaled to fit the window.
-
- You can make fine adjustments to the window size by dragging the Adjust size
- icon. Each time you change the size the drawing will be rescaled. Pressing
- F5 will also select and deselect Full view.
-
- If you deselect Full view the drawing remains unchanged when the window size
- is altered. Clicking on the Toggle size icon will now have no effect on the
- scale. You can, however, adjust the scale of the picture using the Zoom
- facility. Follow the Zoom arrow to open the Magnifier dialogue box.
-
- This allows you to choose any scale between 1/16 and 16/1. You can either
- click on the up and down arrows to change the values, or enter them directly
- at the keyboard (pressing Return to finish).
-
- Alternatively you can change the scale using the Page Up, Page Down and Home
- keys. Page Up doubles the size of the drawing, Page Down halves the size,
- and Home returns the drawing to its default scale ie 1/1.
-
- When a picture is zoomed the point beneath the pointer remains in the same
- position so that it is easy to zoom in on a particular area.
-
-
- Undo and Redo (F8) (F9)
-
- If you have made any mistakes you can rectify them by choosing Undo from the
- Tools menu (or pressing F8). Each time you choose this option a change will
- be undone. If, for example, you wished to undo the last six changes you
- would press F8 six times. Choosing Redo (F9) will restore the changes.
-
- Note The number of changes which can be stored is controlled by the size of
- the undo buffer.
-
-
- Save (F3)
- This option is not available in the demo version.
- A file may be saved as a Poster file, Draw file or Compressed Draw file. All
- three types may be loaded into Poster, Chameleon or Vector. Choices
-
-
- Choices
- =======
-
- The Choices box is opened from the icon bar menu.
- Clicking on OK will make any changes take effect immediately. Clicking on
- Save will make the current settings (including pattern parameters) the
- default settings which will be used the next time Hatchback is loaded. The
- current save options are also saved.
-
- Double-click loading
-
- If this option is selected, Draw and Poster files can be loaded into
- Hatchback by double-clicking on their icons (as long as Hatchback is loaded
- to the icon bar before any other application which loads Draw files by
- double-clicking). If the option is not selected, the files must be dragged
- onto the icon bar icon.
-
- Save simple drawfiles
-
- If this option is selected, saved Draw files and compressed Draw files can
- be used and manipulated in other applications but subsequent editing in
- Hatchback will not be possible. If the option is turned off, saved files can
- be loaded back into Hatchback for re-editing but may not be completely
- acceptable to other applications.
-
- Margin size
-
- When a file is loaded into Hatchback, it is centred in the window with a
- margin surrounding the picture. By default, the margin is set at 20% (of the
- width or height, depending upon which is the greater). This can be changed
- to 50% or any value of your choice.
-
- Undo buffer
-
- The Undo buffer is the amount of memory reserved for storing information
- about the changes which are made. The larger the buffer, the more changes
- will be stored. You can set the size of the undo buffer to suit your own
- memory requirements. If memory is very tight you should choose None but, of
- course, this will mean that the Undo facility will not be available to you.
- The Ridiculous option is available for those with vast amounts of memory.
