Based on work I started in PureBasic Interface to OpenCV.

[ Click anywhere on the image to set a new X/Y position, resetting the effect. ]

Image Waves:
- Drag & Drop image uploading
- Press the 'Enter' key to toggle the Wave Map
- Press the 'Spacebar' to trigger the effect from the last location
- Right-mouse-click the display area to open a context menu
-- Open New Image
-- Toggle Wave Map
-- Trigger Waves
-- Open Control Panel
-- Close Image Waves

Hi idle,

Thank you for your kind words, and for confirming compatibility to the Linux OS.

----------------------------------------

Fixed an issue reported by AAT.

Updated:
- added 1 menu item
-- Open Control Panel: adds the ability to fine-tune the ripple effect

NB*: Settings are save to an ADS (Alternate Data Stream) attached to the default image (only available in the Windows OS).

Hi walbus,

Thank you, I'm glad you liked it.

-------------------------------------

Updated:
- fixed a couple issues with the Control Panel
- added tooltips to the Trackbars

Nicely done.

I think there is a nice movie in the make... this code, your spider code...

Hi Joris,

Thank you. I'm not sure about a movie though, unless it's about a programmer who drinks way too much coffee while creating useless programs :lol:

----------------------------------------------

Updated:
- added an additional setting to the Control Panel
-- Wave Distance
- refined some settings for a smoother effect

NB*: Renamed the program to Image Waves.

There's even there any words, to describe your splendid and numerous works ??? :oops:

Thanks a lot for sharing

Hi Kwai chang caine,

Thank you for trying the program and posting a comment, it's very much appreciated.

--------------------------------------

Updated:
- applied a few program and cosmetic changes

NB*: To see a slightly altered version try the example cv_water_ripples.pb located in PureBasic Interface to OpenCV.

Thank you JHPJHP for this program and the spiderweb program. i see you convert some programs from the PureBasic Interface to OpenCV to a standalone programs, i think this is good and appreciable, since it is in this way will be available to a more users.
regarding the image waves, i can't change the blue back ground since i barely see the black waves in the wave map section. in fact i am lost trying to figure out where is that canvas background color lines.
thanks for all your efforts

Hi applePi,

You're very much welcome.

You're correct that one of the reasons why I converted the programs from PureBasic Interface to OpenCV was to bring them to more people, but also to bring more people to the interface.

The colors blue and black are a result of the byte-order determined by the OS; Windows is BGR while OSX is RGB. The color value is part of an algorithm used to determine the X/Y displacement, so this cannot be adjusted without affecting the output.

WaveMap / LUT (Lookup Table):
- the declaration in the Procedure BlendWaveAndImageLUT includes the WaveMap image, making a ProcedureReturn statement redundant
- SetWaveMap is one of the variables in the main window loop determining which image is drawn on the CanvasGadget

NB*: The program has been updated removing redundant ProcedureReturn statements, including a few optimizations.

It would be great if the interface was cross platform since OpenCV is available not only on Windows but als on OSX and Linux.

Hi wilbert,

A cross platform version of PureBasic Interface to OpenCV has been on the back of my mind for awhile. I don't think I would recreate the entire interface (200+ examples), but maybe an OSX and Linux version of PureBasic Interface to OpenCV :: Demo (32bit / 64bit) :?:

agree multi-OS demo would be supercool

You don't have to recreate all 200+ examples.
If you can do a few cross platform examples and maybe make new examples cross platform, that would already be great
