SmillaEnlarger is a small graphical tool ( based on Qt ) to resize, especially magnify bitmaps in high quality.

One fascinating aspect of analogue photography is, that by means of an Enlarger, you can pick an interesting part of your photo and blow it up to poster-size. Whereas zooming into a digital photo just leads to a bunch of colored blocks.

My little tool tries to be an easy-to-use equivalent of the analogue enlarger for the digital photography:

You choose an image file, pick a rectangle and decide how big the result should be ( by scaling factor or by giving width or height of the result ), then you press calculate and get an enlarged image with smooth curves instead of blocks, where edges in the original stay ( more or less ) unblurred edges in the result.

And where did Lusteck get the name for his application? “My Siberian Husky is named Smilla, after the title character from the novel Smilla’s Sense of Snow, and I used a photo of her for enlarger testing.”

...kann man Bilder und Bildausschnitte ohne starke Qualitätsverluste vergrößern - durch die eingebaute Vorschau kann man die zu erwartende Qualität abschätzen. Die vorgeschlagenen Parameter sind erstaunlich treffsicher, aber ein bißchen Rumspielen lohnt ...

Changes in SmillaEnlarger 0.8.5:


Some interface improvements

Drag & Drop: drop files and images from other programs onto the enlarger window to open them

Clipboard paste

Help-menu added

Enlarging uses less memory

Code cleanup: algorithm moved into BasicEnlarger<T> template
( where T can be any float-vectorspace-class with dot-product and norm)

Support alpha channel

Added FractNoise slider: modify result colors and contours with plasma fractal noise

slightly changed dithering - should now better preserve original hue

Changes in SmillaEnlarger 0.8.9:

The interface is laid out more clearly using Tabs.

Calculations are now moved into a job queue and processed in the background while you can continue your work at once.

Batch Processing is implemented. When you drop folders or multiple files, they are directly pushed into the queue using the current settings.

The settings of the parameter sliders are saved now.

The Help was improved.

You can use SmillaEnlarger as a command line tool
( use SmillaEnlargerCL.exe ).
