- NAME
- getami - display an RLE image on a Commodore Amiga and optionally
- save it as an IFF ILBM file.
-
- SYNOPSIS
- getami [-w width] [-h height] [-o IFFfile] [-fdlb3H] [input_file]
-
- DESCRIPTION
- Getami displays an RLE image on a Commodore Amiga. The program tries
- to display the image in the best possible way, using HAM mode and
- overscan when appropriate. Both NTSC and PAL Amigas are catered for.
- In addition, the program allows you to save the displayed picture in
- IFF format, using Christian Weber's iff.library.
-
- Getami understands the following options:
-
- -w width Override the screen width computed by getami. Eg., use
- -w 640 if getami selects a screen resolution of 320x400
- (because the picture will fit in it), but what you really
- want is 640x400.
-
- -h height Override the screen height computed by getami.
-
- Apart from the example mentioned above, these two options
- are probably obsolete.
-
- -o file Make getami act as an RLE->IFF converter: after rendering the
- RLE file, getami saves the image in IFF form in the file
- specified, then exits.
-
- -f Render the image flipped vertically. This option is necessary,
- because rleflip -v often requires more memory than available
- on the amiga.
-
- -d This option causes getami to dump the color map it computes
- into file "cmap".
-
- -l This option causes getami to ignore the color map it
- computes, and to replace it with the color map stored in file
- "cmap".
-
- These two options must be used if you are using getami to
- create IFF files to be used as frames for an ANIM file, as
- all frames have to have the same color map.
-
- -b Render the image in black and white. This allows you to
- display pictures at full resolution. (To display in color a
- 640x400 picture with more than 16 colors, you need to scale
- it down to 320x400, not to mention the unavoidable blurriness
- introduced by Hold And Modify.)
-
- -3 Render the image in 4096 colors without using HAM. This is
- achieved by rendering the image in three screens, one for each
- of its r,g,b components, then flipping through them in rapid
- succession. Because of this rapid flipping, the image
- flickers. This is especially noticeable in conjunction with
- interlace. If you are sensitive to screen flicker, please do
- not use this option.
-
- -H Force rendering of the image in HAM mode. Useful in rendering
- animation frames, if getami happens to render some of the
- frames in HAM mode and some in another mode.
-
- MENU OPERATIONS
- You can select the following actions from the menu bar:
-
- SAVE Save the rendered picture in an IFF ILBM file. The picture will
- be saved in a file with the extension ".ILBM". Eg., if you are
- rendering a.rle, the picture will be saved in a.ILBM. If the
- picture you are rendering comes from the standard input, you
- will be asked to specify the name of the IFF file. This action
- can also be invoked by pressing right Amiga-S.
-
- SAVE AS Same as SAVE, but you are always asked for the name of the
- IFF file. To cancel the save, simply give a null file name.
- This action can also be invoked by pressing right Amiga-A.
-
- These two operations can only be invoked if you have Christian
- Weber's iff.library in your LIBS: directory. If you save a
- picture which has been rendered with the -3 option, you will
- actually create three files, with extensions ".r", ".g", and
- ".b", respectively. You can view this image using the show3
- program.
-
- QUIT Exit the program. This action can also be invoked by pressing
- right Amiga-Q, or by clicking on the invisible gadget at the
- top left corner.

- AUTHORS
- Eleftherios Koutsofios (ek@ulysses.att.com) wrote the first version of
- this program, including the HAM rendering algorithm.
-
- Kriton Kyrimis (kyrimis@theseas.ntua.gr) added support for intuition,
- overscan, saving files, the B&W and 4096 color display modes, and made
- all sorts of improvements.
