Which file formats you need suppored image processing program?
To me 24bit IFF,PNG,JPEG mainly. I talk writing side my project verylkely loads files using Datatypes. Even maybe writing if i understand how is done...

@Vanhapolle

PSD with layer, paths etc.

@Vanhapolle

BMP for all those bitmaps out there i cannot use

@Vanhapolle

Raw formats such as CR2 and NEF for Photo editing

@Vanhapolle

- Animated gifs AnimGIF standard, view anim, reverse play, view frames, extract frames, optimize frames and colors.

- Animated PNG APNG standard, so then a viewer/elaboration software could be used as MIME into OWB that lacks viewing of APNG.
Also here it should view anim, etcetera.

- 96Bit images also RAW taken from high fidelity scanners
(they must be imported files as Amiga/AROS/MorphOS still don't support drivers for 96bit colors scanners)

- HDR images

Such a program should also have features of extract Alpha channels from files, and also capability of saving extracted alpha as separate files.

96bit processing sounds nice idea but expect needs writing very custom code i dont even understand how such values can be processed with c i mean how write and read 24bit red value for example expect maybe i do such way but even then i must reducre colours to 8bit per rb value to previews..... and currently my idea is going no alpha chanel support (there is no reason support it) and process whole image in time. i dont have ideas how do tools which allows modifying only single areas what users "paint" like photogenics. actually many other things. actually i want do brush (some which are unavailable elsewhere i think and some which we have old photgenics 1.2a "if my algorithm simulation in my head works correctly" i can of course code such thing but becouse i cannot do brush tools at least yet i dont have point do such parts) stuff but i dont yet have skills do such ideas. one parts of my idea is possible but userinterface side is hardest side which i dont understand how this painting window is done. GUI coding is hardest part allready even more when i think how do window what we have in SketchBlock. Actually somehow is easier do such modules for another program but there is no such program which has api which allows made custom brushes etc. brushes dont mean same what they mean in Deluxe Paint and Personal Paint.
ps. i look what i can add but bmp support sounds good.

Some users have nice ideas but not fore freeware programs.

Mickymouse soft...

I think there are some good 96 bit imaging algorithms in the Open Source circuit.

There are excellent free image processing software in the PC Wintel circuit, such as XNView and IrfanView, why not try freeware for us too?

Alternatives:

- You can distribute your software as Giftware so any amigan could donate you money.

- Distribute it thru Amistore: People will purchase it from Amistore, so you can earn money and your work will be rewarded then.

- Insert publicity advertising in it.

Convert everything to floating point. Final conversin to to 8bit perchannel for display is then as simple as

float inv255 = 1.0/ 255.0

Colour.argb_Red * inv255 etc

Ofcourse such may be slow on classic hardware but should be okay on AmigaOS4 MOS AROS and WinUAE. You'll need to put a lot of thought into optimising though.

and currently my idea is going no alpha chanel support (there is no reason support it)

Really?
Quote:

and process whole image in time. i dont have ideas how do tools which allows modifying only single areas what users "paint" like photogenics.

By alpha blending with a mask or more simply a singe transparency bitplane.

actually many other things. actually i want do brush (some which are unavailable elsewhere i think and some which we have old photgenics 1.2a "if my algorithm simulation in my head works correctly" i can of course code such thing but becouse i cannot do brush tools at least yet i dont have point do such parts) stuff but i dont yet have skills do such ideas. one parts of my idea is possible but userinterface side is hardest side which i dont understand how this painting window is done.

For painting in the window in real time, you need to come up with a scheme for only redrawing what has been modified. Keep track of the "damaged" area. And only blit that much into the screen at one time. I have serveral rastports / bitmaps that are off screen and only combined at the point of display.

PS I hope you won't mind this feed back, but as your english is not strong ( no critcism there it's not your first language) you could make your posts much easier to read by splitting up into short paragraphs.

Maybe even leave a line between each thing you have to say.

This makes it much easier to fiollow, especially on a computer monitor.

I try use paragraphics if rememer. and is not my first language,and i few have afasia,cerebral palsy,autism i think which can maybe get own part why i am me not anyone else. and i can rember wrong a starting diagnoses. these are so many but i dont mean anything like aids.:)
ps.at least what i know feed back is writen feedback...

@broadblues

i know paiting in window needs these things to such thing unerstading is not problem but putting itscode is hard part. its like writing english but i say my native tongue is also hard write to me actually if you dont know my native tongue is one world hardest languages what i heared but still i heared also 2nd language what computer talked.
BUT:
main problem is write painting window i mean how do window which shows part of bitmap or maybe magnified part of bitmap.

Alphachanel support hymph i must think it at least then i someday get brushes working... and maybe i allow use it to mask to effects.(another chocie is maybe user selected picture). And i say again i code mainly my personal needs and things what i can easily do. somethings indeed have point decimal numbers but they need convertting back before display. which is maybe bitslow.
btw i care winuae if possible i even want code programs dont work with it.:) i am joking becouse if my amiga goes cr*p is good solution then before i get maybe again real hardware maybe depends price etc...and this project unlikely goes supporting classic amiga becouse wants truecolor data form datatypes no only this (this not biggest problem) but needs some things writen old amigaOS and Amigaos4.1 final way. I still actually dislike this new way: IExec->OpenLibrary(GagToolsLibrary);
ps. GagTools is not typo is funny? joke!

Also i maybe have idea for main window which shows selected area of picture 100%. Now is hardest part do only left.:) to me hardest.

@Vanhapolle

I would like to use PNG, JPEG, animGIF.
(and legacy anim and iff is nice extra, then CDXL and HAM6, HAM8)

@Vanhapolle

So ask a right price for your work! There's absolutely nothing wrong in closed source, commercial software, nor in prices you might apply to the port of a open source project, if you feel you needed to spend important hours of your life working on it. The Amiga world is plenty of examples of open source programs developers had asked to pay for, so yours would not be a newcomer. Don't expect, though, to get rich. Obviously a brand-new, written from scratch application would be more welcome in the paid arena.
