Visual Image Effect (GUI)

[GreenCan]

Following to my Image Crop Tool, this is a new function to visually apply effects on an image

Version 1.0.0.1

  Visual Image Effect UDF 1.0.0.1.au3

Features:

• Brightness/Contrast
• Hue/Saturation/Lightness
• Blur
• Color Balance (RGB)
• Levels (HMS)
• Sharpen
• Tint
• Undo (New)

Similarly to _CropImage(), _ImageEffects(() will scale the image down to get it visible on screen, all effects are implemented and stacked into an Effects History array, and replicated to the original image while saving.

Clicking the OK button after having moved the sliders, implements the filter!

Some particularities:

Blur and Sharpen effects give different results with the same radius, this issue has been taken into account.  The maximum radius of 255 will therefore be limited if using a scaled image, so that the final effect is guaranteed the same on screen as on the bigger sized image file. (see $h_Blur_Btn and $h_Sharpen_Btn and in _SaveLossless() how I rescale the Radius to get it right in the big image)

The function saves to images for demo purpose

• _SaveClone() will save the image displayed into the GUI (You can remove this line as only for demo purpose)
• _SaveLossless() will save the original sized image with all applied effects

You will see that the result is identical on both created image files.

BugFixes:

• After applying a filter, I forgot to reset the filter values, fixed

Enjoy

PS as from tomorrow, I will be offline for a week...

You could add a pre viewer for directly see changes applied.

​Not sure what you mean.. , the whole GUI is a preview already, when you move the sliders, you see the effect of your change immediately. 

What i will add in the next version is an undo panel (a bit like Photoshop). because I keep an history of all the changes, I can easily rebuild the effect from step one to the last step.  As you know most of the effects are destructive but with the history stack, it's easy to workaround the issue.  Example of stack:

Row|Col 0|Col 1|Col 2|Col 3
[0]|8|||
[1]|Tint|-76|-54|
[2]|Sharpen|13|47|
[3]|Levels|87|-11|0
[4]|Blur|8||
[5]|HSL|-11|11|0
[6]|Blur|12||
[7]|BC|16|7|
[8]|ColBal|-2|8|0

​The two scripts are way too different to be integrated into one GUI, I don't know how I would manage the cursors, crosshair and shading if using while combing the functions of this script. But I can add a 'Crop' button in this script calling the Crop tool for the current image, that would be no issue and is even a good idea.

Before you ask, I have no intention to rewrite Photoshop

..ok, I'd like that

from there matching the coordinates and over imposing to the original image would allow for blurring an area and apply the, now filter, to any area I'd like to blur or apply any of the effects that this script provides.

V 1.0.0.1 already implemented.

Now possible to Undo filter step by step backward (Photoshop alike undo)

Fixed an issue with resetting filter values.
