Lightweight image viewer powered by OpenGL.

I use this viewer daily for:

• Quickly browsing through a list of images.
• Determining the parameters of the area occupied by a sprite on a texture.

Advantages:

• Compact and fast.
• OpenGL support for smooth operation.
• Simple interface for quick image viewing.
• Sprite parameter determination feature.

Wide range of supported formats:

• Graphics formats: PSD, AI, EPS, PNG, XCF, JPEG 2000, JPEG, TIFF, ICO, DDS, GIF, BMP, TARGA, PNM, XWD, XPM.
• Image formats: SCR (ZX-Spectrum), WebP, OpenEXR.

Additional features:

• Multi-page TIFF.
• PNG frame support in ICO.
• View each GIF frame separately.

Advanced features:

• ICC color profile support: Ensures accurate color reproduction using embedded ICC profiles.
• Image file information: Access EXIF and other data stored in the image file (<e>).
• Smooth loading: Loads images in a separate thread with a progress indicator.
• Convenient navigation: Creates a file list and allows quick navigation to the desired position.
• GIF animation support: Plays animated images in GIF format.
• Pixel information: Displays the coordinates and color of the pixel under the cursor (key -p or <p>).
• Area selection: Allows selecting a part of the image with a frame to determine coordinates and area size.
• Quick zooming: Convenient zooming of the image using the keyboard or mouse.
• Automatic scaling: Automatically adjusts the image to fit the viewer window.
• Multi-page images: Views multi-page images using the PgUp and PgDn keys.
• OpenGL: Utilizes OpenGL for high performance and smooth operation.
• Large image splitting: Splits large images into multiple textures for performance optimization.
