I need help with picture resize

duni · October 13, 2011

Hi all! I am new in this programming language and i need some help. I'm trying to make a program that collects a number of pictures in a folder, it comes out the screen to give you the option to put a new resolution, the resize according to what you put and keep them all in a different folder and resized, but I can not . I have to use ImageMagick.

Let's see if someone can put a script on how to start or some script similar to what I have to do.

Thank you very much for the inconvenience and sorry for my bad english

Regards,

Duni!

P.D:It is similar to the script that I put, but need not be an image but were several.

The problem is that this script its only for a one picture and i need it for a complete folder of pictures.

I try the next script but i have one problem, the pictures dont appear in the folder. WHY?? any solution??

resizer2.au3

duni · October 14, 2011

Yeah, that function is where I drew but I need one that you can choose your pixels that you want ,not those who enter the program, on a screen that asks you the width and height.

Are you understand me??

duni · October 19, 2011

I have this scrip and I still don´t work . I need to do what i put in the previous post, resize the pictures but putting in a different window the new pixels. I would appreciate if someone help me because its vital for me do this.

Okay, you got something. Now I only need to instead of me screen out of pixels for each picture, leave only once. I do, with one for? Any suggestions? Thank you for the inconvenience!

I leave here the script:

;======================================================================================

; Function Name: ResizeImage

; Description: Loads an image and scales it to desired width or height

;

; Parameters: $fImage: image file to be loaded

; $iW: new image width. If $iW = 0 then default values is 96

; $iH: new image height. If $iH = 0 then default values is 96

; $fDestFolder: destination folder where the scaled image should be saved to

; $fExt: image output format (can be jpg, png, bmp, gif, tiff) - default is PNG, -1 to keep extension

; $fPart: filename part to separate it from orignal name. Default is .resized. -> filename.resized.ext

;

; Requirement(s): GDIPlus.au3

; Return Value(s): Success: True, Error: see below

; Error codes: 1: no filename given

; 2: filename doesn't exist

; 3: image couldn't be resized

; 4: resized image couldn't be saved
