New version of Pixopedia 24 released!

Click here to download Pixopedia 24 2.0 Alpha6 (ZIP file, cca 8MB).

Alpha version does not require username and password and does not expire!!!

Here are news in Alpha 6 build:

1. Some internal program changes. Shell components changed (used for browse and slideshow). Now, there is no nag screen at program start.
2. LUA scripting added. You can create and run various image effects using Lua language scripts. All lua scripts packed with Pixopedia 24 reside in userdef_xml directory together with filters, brushes, etc... You can change and modify LUA scripts as you wish.

   If you want to create your own LUA script, you must pay attention to some Pixopedia_24 functions, constants and variables:

   variables:

   1. vp24_height - height of current image
   2. vp24_width - current image width

   image_flag constants:

   1. image_OUT = 0 - flag to output image
   2. image_INP = 1 - flag to input image

   functions:

   1. fp24_getImageRGB(image_flag, x, y) - returns red, green and blue channel respectively
   2. fp24_setImageRGB(image_flag, x, y, r, g, b) - sets a new red, green and blue channel value
   3. fp24_getImageLuminance01(image_flag, x, y) - returns scaled luminance value [0, 1]
   4. fp24_getImageHSV(image_flag, x, y) - returns hue, saturation and value
   5. fp24_setImageHSV(image_flag, x, y, h, s, v) - sets new hsv value
   6. fp24_showProgress(current_value, max_value) - show perentage of work done. Often used as fp24_showProgress(y, vp24_height), where y is current scanline.
3. New segmentation methods added:
   1. RGB decomposition
   2. HLS decomposition
   3. XYZ decomposotion
   4. YCrCb decomposotion
4. Limited tablet supoort added: pressure only! You can specify to control brush size with pen pressure or brush capacity (or both) You can also turn off and on pressure control. If there is no tablet installed, pressure is always set to 1.

Here are news in Alpha 5 build:

1. MRU/RUF list implemented.
2. Create V/A stream and Close V/A stream removed from main menu. Replaced by mode switching: standard, standard with animation, wavelets, and master/slave mode (currently disabled).
3. Wavelets decomposition added. Currently, this operational mode is intended strictly for artistic effects, not for any kind of image processing and analyzing. Actually I can add some options to perform image analyzing....hmmm....painting program with possibility to analyze CT images...nice idea.
4. Image segmentation added: Laplacian pyramid, Gaussian pyramid, Cheops pyramid, etc. Again, currently this mode is intended for obtaining various artistic effects, not for image processing and analyzing.

   Now, how to work with 3. and 4. When entered this mode, select type of decomposition or (in case of wavelets) filter bank and decompose image. You'll get 4 images Lv0 - Lv3 and they can be of various sizes. To modify segment (level), select the level and click on the thumbnail. Image will be copied to IMA. Now do some modifications (filters, autobrush, etc...). To save modified Level, click on save changes. You can now select some other level and perform some other modifications. To reconstruct image click on reconstruct button. To see what has happened, click on reconstructed thumbnail to get full image in IMA. Tadaaaaaa...you've probably got some crap. Try again.

5. Quadtree method added in Ornaments (actually modified Quadtree). Perform various quadtree recursions on image. Well, this thing needs more explanation but I'm not in the mood today. Just create new image (let's say 600x600), go to Ornaments and draw something on the image. Switch to Quadtree and click Quad it!...complete image is "patterened" according to matrix rules. Now, undo your work (ctl+Z), increase depth to let's say 5 and click on Matrix button. Select some new pattern, click OK and then press again Quad it! button.

   Undo again your precious work, click again on Matrix button and select some pattern. You can probably see some large + and X signs in the boxes. Now imagine that all those boxes are actually your image. X sign in some box means: draw the image (resized of course) in that area of the new image. + sign means: split that image area in 4 parts and iterate. If the box is empty, that means: do not draw nothing.

   Every group of 4 boxes represents one quadrant of the image (subdivided in 4 subqadrants). So, when some subquadrant (let's say 3) in 1st quadrant contains + it will be replaced by 4 subquadrants from quadrant 3, etc...etc....blah, blah, blah....

   If some subquadrant is again subdevided (create and save, ctrl+left mouse button) it will not be replaced with other quadrant, but will be replaced by itself in all subsequent iterations.

   So...just play with various patterns and you'll get it.....I'm quite bad in explanations...maybe some PDF with pictures and step by step guide would be nice.

   NOTE: You can find a lot of informations on quad trees on the web, but its' often used for image segmentation and clustering not for recursive drawing.

   If you want to play with your own patterns, go to Create and save and click with your mouse buttom a little bit around and see what happens.

6. Is there anything else....mmmmm...let me see...Oh yes, I've added help, but the content is still from version 1.0.5...sorry.
