- This is Draw to Sprite, an application to convert draw files to bitmaps. (As the name suggests.)

- Using the Program
- ===== === =======
-
- Load the application by double-clicking its icon in the directory display. For users with just
- a floppy drive the program disc may have to be accessed while converting, so keep it handy.
-
- The icon bar menu has the following items:
-
- Info Standard info window
- Sprite Sprite property window - see later
- Processing Processing window - see later
- Reprocess Reprocess the current image
- Quit Terminates the program
-
- To load a draw file, simply drag the required file to the icon bar icon or to the output window.
-
- Once the draw file is loaded it is rendered using the current settings.
-
- The sprite settings window will be different for users of RISC OS 3.1x and 3.50.
- In the former case the sprite options are:
-
- Sprite Width
- Sprite Height
- Sprite Mode
-
- So, for example to create a 16 colour sprite choose mode 12 or 20, for a 256 colour one choose
- 15 or 21.
-
- The palette 'radio' buttons beside the sprite property group determine the colours for the
- output sprite.
-
- For RiscOS 3.50 (or greater) users, the sprite options are similar to those found in !Paint's
- (version 1.84) create sprite window. It is possible to choose the xdpi and ydpi for the sprite
- as well as render to a 32000 or 16M colour sprite. xdpi and ydpi values of 90 correspond to
- vga resolution. See your user guide for further details.
-
- For all users:
-
- The options in the 'Processing' dialogue box determin how the file is to be rendered.
-
- Automatic scaling means the draw file is stretched or shrunk to fil the given sprite.
- If this is not selected it is possible to enter the scaling in the writable icons below.
- If desired, the values can be incremented and decremented by the arrows beside them.
-
- 1:1 aspect, when selected, ensures the file is rendered 'square'. If this is not selected
- the file fill be stretched in both directions to fit. This means that circles may be rendered
- as ellipses.
-
- If 'Use dithered colours' is selected the computer will dither the colour available to match
- them as closely as possible to those in the draw file. Note that this makes no difference in
- 16M colour modes!
-
- The palette definitions are stored in a sub-directory as 1x1 sprites with the appropriate
- palette. This enables the user to tailor the palettes to his/her needs. Load the file into
- !Paint and alter the palette entries to your requirements.
-
- To save the rendered image, click 'Menu' over the output window. The first menu item's submenu
- is the standard save dialogue box. Drag the spritefile icon to where you want to save the file
- or type in the filename and click 'ok'.
- The other menu items in this menu are functionally identical to those in the iconbar menu.
-
- Known Problems
- ===== ========
-
- There are a few of known problems, but it's getting close to my finals and I don't want to
- be worried by them at the moment.
-
- 1) 2, 4, or 16 colour sprites aren't displayed properly if they have no palette. Select 'mono'
- or colour palette in the sprite dialogue box to get around this.
-
- 2) The hourglass tends to increment in large jumps, giving the impression that not much is
- happening. Just give it a chance - it's probably just rendering a sprite.
-
- 3) The path buffer for the draw file has a maximum of 20Kb. This is sufficient for most
- files, but some, noteably graphs, may be too complicated to render.
-
- 4) Text areas are not supported. This isa bit complicated so it may never get done. However,
- all other text is (rotated/stretched etc).
-
- 5) Could be faster...
-
-
- Please report any bugs to me at the address below. In particular whether the menus widths are
- OK. Risc OS 3.5 sizes them for you, so I can't check. Grrrr. I've left the !RunImage file
- un-squeezed so you can see how it works (if you really want), something which I wish more
- people would do. (Not mentioning authors of SampleCD at all...)
-
- If you have a drawfile which does not convert correctly please send me a copy and I'll see
- what I can do about it.
