Changing image hue

Recommended Posts

Mikeman27294

Hey everyone.

I want to add a theming engine to a program of mine, so that there is multiple hues, ie red, green, orange, blue and so on. I also want to be able to change the brightness of the background, ie you can choose between a range oflight greys through to dark greys.

I have searched the forum and came across this:

#include<Array.au3>

#include<Color.au3>

#include<GUIConstantsEx.au3>

However, I dont quite understand the hue changing function in this, or the brightness function. Are there any easier ways to do something like this? Otherwise, can someone please help me make sense of the hue and brightness functions?

Thanks.

Finally the autoit tags are working so there u go. Sorry bouth that, it was only showing the first few lines and then it swallowed up the edit button and all those buttons and so on.

Try passing the code, after first switching the post editor in code mode. An post it in that mode to(if posting in normal mode also screws things up.) ...

Erm: Yep ... Don't post in Normal mode ;)

Grr: ... don't even switch to normal mode ... :graduated:

      MapIt is a tile world editor.  MapIt was built around the concept of reversing Dragon Warrior map images.  MapIt can take image input and produce a tile and world array.  
      Changing and replacing tile / world data is easy.  B/c tile world editor.

      CTRL+R in image above to signal replace tile action and I use "G" to Get the tile under mouse.
      A full list of hotkeys can be assigned in the: Help Menu\Hotkeys
       
      MapParser is a C++ project that scans images for unique tiles. 
      MapIt can be downloaded without MapParser. MapParser can be toggled off in the Scan_Image dialog. Without MapParser, MapIt will use the Scan_Tiles() function written in AutoIt ; which is 100 * slower Idk. If MapParser.exe will not run for you:      Installing Visual C++ Redistributable for Visual Studio 2015 should fix it: https://www.microsoft.com/en-us/download/details.aspx?id=48145   
      You can start with example world and tiles.
      Example world was made following these steps:
      Started with a tile map image of DragonWarrior3 town of: Reeve From MapIt World Menu \ New \ Scan_Image dialog, I set the area to exclude the key legend to the far right of image. After scanning the map image to world and tile array.  I removed a few of the map artifacts.  More work could be done on this world; removing unwanted tiles, but it is fine for now. I saved my world to disk.  This creates folder: Worldname: Containing folder of Tiles and a Worldname.txt. Using The Gimp, I edited some tiles to have a transparent color: Stairs, Trees, Desk Tables, Chest-of-drawers, Chairs, Signs, Doors, Beds. I changed the world layers to 2: World Menu \ Properties. F9 Finds all selected tile on current layer and changes to a new selected tile on new layer. I used F9 to change all Trees on layer: 0 to Trees on layer: 1. Then I used F9 to change all Trees on layer: 0 to Grass on layer: 0  
      In this video you can see how I used the Tile Menu \ Replace From Disk option to remap tile images to my custom tiles.  Conveniently my tiles already have a transparent pixel.
      See video for how that was done:
      To use the example world:
      First unzip the world save file: http://songersoft.com/programming/mapit/worlds/Reeve_Swapped.zip From the World Menu: choose \Load Navigate to the Reeve_Swapped.txt located in the extracted zip. Or you can scan any image.
      The map images I used are here: http://www.realmofdarkness.net/dq/games/nes/dw3/maps/world
      For download, videos, and example of created world file data; please visit the MapIt webpage: http://songersoft.com/programming/mapit/mapit_about.phtml

      Howdy, I've gone through a lot of au3 forums, and I once had a working Imagesearch script that I got from here.  However, and i'm just totally not sure how but my imagesearch scripts aren't working anymore.
      I'm not new to au3 but i'm not the most experienced with it's syntax/commands.

      Anyways, I've looked over the big threads involving imagesearch.

      Does anyone have a working Imagesearch x64 for win10 that is currently working as of the date with the post.

      Dll's and what not is fine, just when I tell the script to run, I want to be able to find the image on the screen!
      Can't find a working copy so if anyone has one please send it my way lol.

      I've taken all the imagesearch downloads and what not and have played with them but I can't get any of them working on my end, despite others saying they're working.
      Thanks.

      I would like to know if it's possible to pass an image recognition (captcha) system.
       
      What are the ways to achieve this?
      Just the references or links is enough for me by now.
       
      Thanks by now!
       
      Thanks!

      Dear AutoIT Community.
      I am currently working on a program that will display lots of images in a scroll down GUI.
      I create the GUI based on the number of images, which works fine.
      But all images I place using GuiCtrlCreatePic above a threshold of around 32000 pixels (cant say exactly) are placed at negative locations and finally will reach 0 again
      and will then populate on top of the images placed there before.
      For $i = 1 To $Images[0] ; Get picture dimensions $hImage = _GDIPlus_ImageLoadFromFile($ImgRep & $Images[$i]) $iX = _GDIPlus_ImageGetWidth($hImage) $iY = _GDIPlus_ImageGetHeight($hImage) _GDIPlus_ImageDispose($hImage) ; Resize & place images in GUI $Pic[$i] = GUICtrlCreatePic($ImgRep & $Images[$i], $Spacer, Round($yPos, 0), $MaxImgWidth, $MaxImgWidth * ($iY / $iX)) $yPos = $yPos + $MaxImgWidth * ($iY / $iX) + $Spacer $log = $log & "|" & $yPos $currentlut = $Images[1] Next I have found a limit at 32767 pixels for some GUI elements when googling around.
      Can someone tell me how to circumvent that?
      thanks!
      cheers
      Felix
