graphic file conversion

[1/5] from: galtbarber:mailandnews at: 4-Aug-2000 19:42

Hi, I just did a screen snapshot in windows, then pasted it into paint and the saved and you get an enormous uncompressed windows bmp. Could I use some trick in Rebol/View to turn it into a gif file or other nice format? I know View must be able to read gif jpg and maybe some others in order to render them on faces. Can it write them, too? Is there some lousy gif patent that lets you provide gif readers but not gif writers? -Galt

Hi Galt, there is a patent (owned by unisys). My understanding is that unisys does not charge any royalty fees if the software is free, however. At 07:42 PM 8/4/00 -0400, you wrote:

Sadly - it can't. Although REBOL's philosophy is - load and save, and you have to get the same result. Try loading some image though, and you will recognise 'save will save it in rebol format, rather than back to .jpg e.g. REBOL lack something as we know as Amiga datatypes. Hmm, now they are saying they go for e-commerce. Hmm, some e-commerce products know how to deal with various formats. I wonder if we will not get something like Amiga datatypes, as Carl surely knows the value and openess of such architecture. Current image format manipulation is really a toy for quick builds of reb-forms, catalogues, etc., just don't try to save back to .jpg, .gif or .bmp ;-) PS: leaving for one-week vacation to The High Tatras ... see you guys next week ...

Hi, actually I think there is a REBOL program that can compress and write JPEGs, and it's the webcam at http://demo.rebol.net/webcam/ It overlays webcam image with REBOL logo and current time. At least I think it's a REBOL program, quoting Carl from message 220407: [carl--rebol--com] wrote:

But I don't know how to do it with released REBOL versions. -- Michal Kracik [Petr--Krenzelok--trz--cz] wrote:

I would recommend a better screen shot tool myself. Paint is the program that's messing you up. I'd recommend spending a little money on something like HyperSnap-DX that will give you fantastic screen grabbing capabilities. You can find it at: http://www.hypersnap-dx.com/hsdx/ I just yesterday wrote an image browser in REBOL/View that takes advantage of the auto save features in Hypersnap using one of many different output formats, bmp in this case. This permits me to browse through a series of images I snapped and write descriptive text for every snap. Just stay away from the lame Microsoft software and everything is good.
