Auto show area coordinates
If this option is ticked,
then the coordinate display window will be opened every time the area
mode is selected. If not ticked, then the area coordinate window will
not open when the Area mode is selected, but can be opened at any time
by double clicking on the red border of the area (more details below).
Use desktop font
If this option is ticked, Snapper will use the configured desktop
font to show the coordinates in the top bar of the area outline. If
not ticked, then Snapper will default to using the Homerton font at 12
pt.
Note that Snapper uses the ×
(multiplication) symbol in the top bar of the area outline. Some fonts
do not include a full set of characters. When a desktop font is
configured, Snapper checks the 'width' of this character and if it is
very close to zero, probably meaning it is absent, it falls back to
using lower case x. There may be occasions when a font includes a
different character in the position corresponding to the ×
character in Latin-1. If this is the case, then switch off the desktop
font - the ROM based Homerton font will then be used.
Add filetype extension
If this option is ticked, then when saving the snap in either PNG
or JPEG format, Snapper will automatically add the /png or /jpg
extension to the filename.
JPEG quality
This is the compression factor (and hence quality of image) that
will be used when saving the snap in JPEG format. The default setting
is 75, but can be set in steps of 5 between 20 and 95, by means of the
bump arrows, the lower the quality setting, the poorer the quality of
image. Quality settings less than 20 can introduce various artifacts
and banding and are not reccomended. Settings above 95 give much less
compression. If very high quality is necessary, then use a lossless
compression method, ie PNG.
Convert sprite format
Save sprite in RO 3.5 format
ROOL have introduced a new sprite format (newer than the so-called
new format introduced with RISC OS 3.5) and recent versions of RISC OS
5 make use of this. In addition, the latest hardware, e.g. IGEPv5 and
Titanium, have the red and blue colours in the new sprites
interchanged. When you make a screen grab on such hardware, the sprite
generated will be in this new format. This may be of no consequence on
the hardware being used. However, older hardware/OS versions may not
understand the new format. In addition, a lot of older software cannot
display or manipulate such sprites, even on the new hardware. Snapper
therefore offers the option to convert these newest sprite types to
the older RISC OS 3.5 format before saving. The sprites should then be
usable on legacy hardware, OS, and software. This option must be
ticked for the sprite conversion to occur, otherwise the saved sprite
will be in the native format of the hardware and OS version.
Convert 64K to 32K sprite
RISC OS 6 first introduced the 64K colour depth screen mode and
sprites. While these can be viewed on RISC OS 5 and 6, they cannot be
used on RISC OS 4. If you are saving in the RISC OS 3.5 format, then
this option gives you the choice of saving either as a 64K sprite, or
as a 32K sprite. When ticked, the 64K sprite will be converted to the
32K version before saving. Remember, if the option Save sprite in
RO 3.5 format is not ticked, then the saved sprite will be a 64K
sprite in the native format of the hardware and OS version, whatever
the setting of Convert 64K to 32K sprite.
To summarise
If the sprites are being converted from RISC OS 5 format to RISC OS
3.5 format then the following will apply.
- 32-bit 16M colour screen mode
- Converted to a 32-bit 16M colour RISC OS 3.5 sprite with the
red/blue colours in correct positions
- 16-bit 64K colour screen mode
- Converted either to a 16-bit 64K or 16-bit 32K colour RISC OS 3.5
sprite with the red/blue colours in correct positions
- 16-bit 32K colour screen mode
- Converted to a 16-bit 32K colour RISC OS 3.5 sprite with the
red/blue colours in correct positions
- 16-bit 4K colour screen mode
- Converted to a 16-bit 32K colour RISC OS 3.5 sprite with the
red/blue colours in correct positions
