I cannot get the imagesearch to work, even though I know the picture is on the screen. Am I doing anything wrong?


Code:
F2::


ImageSearch, , , 0, 0, A_ScreenWidth, A_ScreenHeight, C:\Users\Chris\Desktop\istest\l158palace.bmp

if ErrorLevel = 2
    MsgBox Could not conduct the search.
else if ErrorLevel = 1
    MsgBox Icon could not be found on the screen.
else
    MsgBox The icon was found.

return
[/code]

Try adding CoordMode, Pixel so it looks at the whole screen rather than the coords of the active window. Also make sure the image you are searching with is cropped to the necessary area only, and make sure you read the Remarks section on ImageSearch

Code:

F2::
CoordMode, Pixel
ImageSearch,,, 0, 0, A_ScreenWidth, A_ScreenHeight, C:\Users\Chris\Desktop\istest\l158palace.bmp

if ErrorLevel = 2
    MsgBox Could not conduct the search.
else if ErrorLevel = 1
    MsgBox Icon could not be found on the screen.
else
    MsgBox The icon was found.

return

1: Dont use BMP's with ImageSearch unless you have read the manual very closely.
2: Put the image in the script directory and try that, Operating system/firewall maybe blocking these from being accessed by other programs.

I recommend using PNG for the imagesearch.

Your coding looks good, except "CoordMode, Pixel " as entropic suggested.
Here are some other areas I have found, some repetition wih previous poster.
1. BMPs must be at least 16 bit (per manual) I usually use 24 bit
2. Is the image you are searching for fully visible ?
3. Is the image area part of your program or another ?
4. is the image im a game or in some other program ? games are sometimes hard/impossible to do imagesearch and pixelseaches on.
5. Try adding a fake image of your own and verify that the search can find it.
Here's example code, place it before your ImageSearch:

Code:
%image%=C:\Users\Chris\Desktop\istest\l158palace.bmp  ; <--- this is your image

Gui, -Caption  gui, margin, 0, 0
gui, add, picture, section vmybutton , %image%
gui, show,xcenter ycenter
