It has 512kB of dynamic memory and captures colour images from video or camera in real-time (it doesn't need a freezed still frame). Software supports AGA chipset and new @{"graphics modes" LINK TRYBY} - HAM8, 256 colours etc. @ENDNODE @NODE TRYBY "Graphics modes" Graphics modes are dependent on type of computer : @{"Amiga 500/600/1500/2000/3000" LINK A500TRYBY} @{"Amiga 1200/4000 " LINK A1200TRYBY} @ENDNODE @NODE A500TRYBY "Amiga 500 graphics modes" @{b}Amiga 500/600:@{ub} @{u}Width: Height: Colours:@{uu} 320 x 256 16,32,@{"HAM6" LINK HAM6} 368 x 256 16,32,HAM6 320 x 512 16,32,HAM6 368 x 512 16,32,HAM6 640 x 256 16 736 x 256 16 640 x 512 16 736 x 512 16 @ENDNODE @NODE A1200TRYBY "Amiga 1200 graphics modes" @{b}Amiga 1200:@{ub} @{u}Width: Height: Colours:@{uu} 320 x 256 16,32,64,128,256,HAM6,@{"HAM8" LINK HAM8} 368 x 256 16,32,64,128,256,HAM6,HAM8 320 x 512 16,32,64,128,256,HAM6,HAM8 368 x 512 16,32,64,128,256,HAM6,HAM8 640 x 256 16,32,64,128,256,HAM6,HAM8 736 x 256 16,32,64,128,256,HAM6,HAM8 640 x 512 16,32,64,128,256,HAM6,HAM8 736 x 512 16,32,64,128,256,HAM6,HAM8 1280 x 256 HAM8 1472 x 256 HAM8 1280 x 512 HAM8 1472 x 512 HAM8 @ENDNODE @NODE HAM6 HAM6 (@{i}Hold And Modify@{ui}) is a special mode that allows you to produce up to 4096 colours on the screen at the same time. It is possible because the value in the colour output circuitry is held, and one of the three components of the colour (red, green, blue) is modified for each pixels. In this mode there is 16 basic colours in palette. @ENDNODE @NODE HAM8 HAM8 (@{i}Hold And Modify@{ui}) is a special mode that allows you to produce up to 262144 colours on the screen at the same time. It is possible because the value in the colour output circuitry is held, and one of the three components of the colour (red, green, blue) is modified for each pixels. In this mode there is 64 basic colours in palette. @ENDNODE @NODE INSTALACJA "Installation" Use "Installer" to install software on your hard disk or floppy disk. The software needs "fg.font" in directory "FONTS:". If it's not installed, the program attempts to open this font from volume"FG24:". @ENDNODE @NODE KOMPLET "FG24 completation" - @{b}FG24@{ub} digitiser - 25M/25F cable - 3.5" diskette with @{b}FG24@{ub} system software @ENDNODE @NODE OPISPROG "FG24 user's guide" MAIN SCREEN @{"Control panel " LINK WCZYTOBRAZ} @{"Animation " LINK ANIM} @{"Screen Mode " LINK EKRPARAM} @{"Show Picture " LINK WYSWIETL} @{"Open " LINK WCZYTAJ} @{"Save as...

They influance image only during decoding. In the middle is situated a preview window. You can click it or click button @{b}Preview@{ub}. To end preview mode click and release left mouse button. A captured image is shown in the window. You can show it on screen clicking @{b}Load@{ub} (a moire effect is correct and it disappears after decoding image). In an interlaced mode wait time can be sometimes slightly longer as the software attempts to check and (if needed) swap frames (it sometimes gives no result - but very rarely). If there is no FAST RAM the screen will blank during loading data into buffer (in this case the preview window can be a bit disturbed due to stopping the program by custom chips). Now you can @{b}Decode@{ub} data. A suitable palette will be computed. @{b}Palette@{ub} computes new palette, but only after having decoded video signal. It's useful when number of colours was changed but not the resolution of the 24bit buffer (in HIRES and SUPER HIRES modes the resolution of the 24bit buffer is the same - like in HIRES ). @{b}Menu@{ub} shows main screen. Gadgets on the bottom of the control panel : The first one @{b}Filter@{ub} serves to choose kind of filter: Laplacian Gaussian Blur Bas relief Diagonal Horizontal Vertical North North East East South East South South West West North West Wood cut Sharpen 1 Sharpen 2 Sharpen 3 Field @{b}F:@{ub} - determines power of a filter (in percents). Next button, when it is checked, executes a filter between decoding data and computing palette (used only at decoding). @{b}Execute@{ub} - executes choosen filter. @ENDNODE @NODE ANIM "Animation" @{b}Animation@{ub} - this panel enables to control recording and playing frame sequences. There are two possible modes of work: black & white - 320 pixels for 128 lines, max 256 greyscales, colour - current screen (not interlaced modes). @{b}Delay@{ub} - specified in 1/50 of second (a time of displaying one frame) time which should elapse after pressing @{b}Record@{ub} button to start recording of frames. @{b}Number of frames@{ub} - max number of frames (it is limited by free memory). @{b}Interleave@{ub} - coming frames will be stored in memory every frame beginning with frame number given in field @{b}S:@{ub} ( e.g. Interleave = 2, S:1 ==> frames will be stored at following locations : 1, 3, 5, 7 etc. ). New window opens in place of filters window ( you can also acces filters by clicking @{b}Filters@{ub} button on the control panel ). From left to right : - current frame/max frames e.g. 1/5. - @{b}Record@{ub} start recording. - @{b}Repeat@{ub} playing animation in a loop. - @{b}Play@{ub} playing animation once. - @{b}Stop@{ub} stop playing. - @{b}Rewind@{ub} previous frame. - @{b}Forward@{ub} next frame. - S:1 start frame (playing, recording). - N:5 number of frames to recording. After pressing right mouse button we can use @{b}Frame@{ub} menu. - @{b}Cut@{ub} delete current frame and insert for its position next one (for last position clear frame is inserted). - @{b}Copy from buffer@{ub} store current frame in buffer. - @{b}Insert@{ub} copy for current position frame from buffer with relocating following frames (last frame is lost). - @{b}Cut & Copy to buffer@{ub} delete current frame, insert for its position next one (for last position clear frame is inserting) and store it in buffer. - @{b}Copy from buffer@{ub} copy for current position frame from buffer. Displayed frame is destroyed. If you wont to show image without control panel, press key ( it works like right mouse button in non animation mode ). @{b}End animation mode@{ub} - free memory allocated for frames and switch to normal mode. @ENDNODE @NODE EKRPARAM "Screen mode" Available modes dependent on machine: @{b}LORES, LORES LACED, HIRES, HIRES LACED, SUPERHIRES, SUPERHIRES LACED@{ub}.
