Best way to use google image search? [SOLVED]
I would like to download the first 5 images in a folder. THX.
#include <INet.au3> #include <String.au3> #include <Array.au3> Global $sSource, $aImgURL, $sKeyWord $sKeyWord = "pug" $sSource = _INetGetSource("http://www.google.com/search?q=" & $sKeyWord & "&tbm=isch") $aImgURL = _StringBetween($sSource, 'src="', '"') For $x = 1 to UBound($aImgURL)-1 ConsoleWrite($aImgURL[$x]&@CRLF) Next
tesseract doesnt detect the easiest image *image to text*
i have this picture here *attached* and this script here:
$ImageToReadPath = @MyDocumentsDir & "\GDIPlus_Image2.jpg" $ResultTextPath = @MyDocumentsDir & "\Result" $OutPutPath = $ResultTextPath & ".txt" $TesseractExePath = @MyDocumentsDir & "\Tesseract.exe" ShellExecuteWait($TesseractExePath, '"' & $ImageToReadPath & '" "' & $ResultTextPath & '"', "", "", @SW_HIDE) If @error Then Exit MsgBox(0, "Error", @error) EndIf MsgBox(0, "Result", FileRead($OutPutPath)) FileDelete($OutPutPath)
but tesseract doesnt recognized the correct word... and gives me trash back...
this is the image >>
and the result was >> "samm"
the image was an normal jpg and generated with this code here:
_ScreenCapture_Capture(@MyDocumentsDir & "\GDIPlus_Image2.jpg", 712,268,853,284)
Could anybody give me a hint what i can do better to get this easy image to text?
thank u very much!!!
Edit: i also tried to capture the screen as bmp with a higher resolution... nothing changed...
_ScreenCapture_SetBMPFormat(4) _ScreenCapture_Capture(@MyDocumentsDir & "\GDIPlus_Image.bmp", 712,279,853,295)
Image quality is bad compared to paint

Any idea how to make the quality better?
Thanks in advance

Getting image dimensions
Hi there. Sorry to bother again. I don't get the tutorials and examples...
Let's say I want to display an image "E:\img\123.jpg" in a GUI. Usually I'd do that by using GUICtrlCreatePic($path, $x, $y, $width, $height).
Unfortunately, the width and height are changing with every picture and they are unknown as well...
First of all, how I can get the width and height of a given picture?
And is there any way that doesn't require me to constantly delete and create that window from scratch?
