ImageView2D

Screenshot ImageView2D

thyGraphics ImageView2D is a small fast freeware image viewer with sophisticated basic functions and high-quality image presentation.

The viewer is portable and runs without installation and without administrator rights. Direct access to the graphics card with OpenGL and Direct3D enables a highly efficient visualization. Supported are the standard formats Bitmap, GIF, ICO, JPEG, PNG and TIFF but also 3D-TIFFs with volume data and optional vendor specific formats. Header and EXIF data can be read out. The engine works with up to 64 bit per color channel. Details of such high precision data can be made visible with the brightness/contrast dialog or directly shown for each pixel. As a further highlight the order of the images is taken over from the windows explorer. Together with the windows search this results a powerful tool to analyse or enjoy images.

This program is freeware and free for private and commercial use.

Features and Functions

Cache and Prefetch

Preloading and buffering of data enables fast switching between images.

Hardware Acceleration

Direct access to graphics cards enables a fast and highly efficient visualization.

User Interface

Open file...
Opens the "Open file" dialog. The following file name extensions are known:
  • *.bmp, *.dib, *.rl4, *.rl8, *.rle, *.vga
  • *.gif
  • *.ico, *.cur
  • *.jpg, *.jff, *.jfi, *.jfif, *.jif, *.jpe, *.jpeg, *.jps, *.thm
  • *.png
  • *.tif, *.tiff
Of course, files can also be opened by drag'n'drop. In this case, the order of the images is taken from the windows explorer. If the file format does not match the file name extension, the viewer will try to find the correct format automatically and displays an appropriate warning. Likewise, a warning is displayed if the file cannot be loaded completely.
Previous file [arrow key up]
Jumps to the previous file with known file name extension.
Next file [arrow key down]
Jumps to the next file with known file name extension.
Print file
Prints the current file. This corresponds to a click on "print" in the windows explorer context menu. In particular for TIFF files our decoder supports more formats than windows. So it may be that an image can be viewed with the viewer but not printed with Windows.
Delete file [Delete]
Deletes the current file. This corresponds to a click on "delete" in the windows explorer context menu. Depending on the configuration of the operating system, a dialog appears for confirmation, the file is deleted permanently or moved to the recycle bin. To prevent accidental deletion, the delete function is disabled by default and must first be enabled in the settings dialog.
Insert clipboard [Ctrl+V][Shift+Insert]
Opens the image data from the clipboard if the clipboard contains image data.
Insert screenshot as image/video
Opens the screen as an image source. Currently there are two buttons for a still image and a continuous video.
Save image as...
Saves the brightness/contrast-corrected image as Bitmap or PNG.
Fit view to window size
Fits the zoom factor to the current window size, so that the image is shown format-filling.
Zoom in [+]
Reduces the view down to 1.5625 %, i.e. factor 64.
Zoom out [-]
Enlarges the view up to 25600 %, i.e. factor 256.
