Declaration

TImageEnProc = class(TComponent);

Description

TImageEnProc provides image processing and analysis functionality to a TImageEnView, TImageEnMView, TIEBitmap, TImage or TBitmap component. It also handles clipboard operations, undo/redo and encryption.



Generally you will not add a TImageEnProc component directly to your project. It is accessed via the following methods:

1. Using the Proc property of a TImageEnView

// Apply pixelization to the selected area of the image (or whole image if there is no selection)
ImageEnView1.Proc.Pixelize();

2. Using the Proc property of a TImageEnMView

// Rotate the selected image 90 deg.
ImageEnView1.Proc.Rotate();

3. Using the Proc helper property of a TIEBitmap, TIEMultiBitmap, TBitmap or TImage

// Enhance luminosity of an image
bmp.Proc.AutoImageEnhance3();

4. Attached to a TBitmap or TIEBitmap in code

// Load an image rotate it 270 deg. clockwise and then save it
iebmp := TIEBitmap.Create;
iebmp.LoadFromFile('D:\image.jpeg');
proc := TImageEnProc.CreateFromBitmap(iebmp);
proc.Rotate(90);
proc.Free;
iebmp.SaveToFile('D:\output.jpeg');
iebmp.Free;

Note:
◼Pre-built UI is available for most TImageEnProc methods, either as a dialog by calling DoPreviews or a TWinControl component using TIEEditControls.
◼To batch perform effects, editing and color operations use an EffectsChain

Examples

// Prompt user to perform color adjustment on the current image
ImageEnView1.Proc.DoPreviews( ppeColorAdjustments );




// Prompt user to perform image effects on the current image
ImageEnView1.Proc.DoPreviews( ppeSpecialEffects );




// Prompt user to perform editing operations the current image
ImageEnView1.Proc.DoPreviews( ppeEditingFunctions );




// Rotate an image in a TImageEnView 90° clockwise
ImageEnView1.Proc.Rotate(270);

// Reduce the size of an image in a TImageEnView to half its size (so when saved it will be much smaller on disk)
ImageEnView1.Proc.Resample(ImageEnView1.IEBitmap.Width div 2, -1, rfLanczos3);

// Prompt the user to perform image effects on an image in a TImage
ImageEnView1.Proc.AttachedBitmap := Image1.Picture.Bitmap;
ImageEnView1.Proc.DoPreviews([peAll]);

// Increase contrast of bitmap rectangle (0,0,49,49)
ImageEnView1.SelectionBase := iesbBitmap;
ImageEnView1.Select(0, 0, 50, 50);
ImageEnView1.Proc.Contrast(10);
ImageEnView1.Deselect();

// Load an image with a TBitmap, make it negative then save it
bmp := TBitmap.Create;
bmp.LoadFromFile('D:\image.bmp');
proc := TImageEnProc.CreateFromBitmap(bmp);
proc.Negative();
proc.Free;
bmp.SaveToFile('D:\output.bmp');
bmp.Free;
