giv, the G(reat|tk|NU) Image Viewer, is an image and hierarchical vector viewer. It was designed especially for scientific vision and computational geometry.
Release Notes: This is a minor bugfix release which fixes a bug in the display of binary tiff images. It is also the first release to provide a 64-bit Windows binary installer.
Release Notes: This major bugfix release solves display discrepancies in the marks viewer, in the state of balloon popups, in caliper-text on windows and in other places. It adds several new features, including multi-line text annotations, shadows below the text, and persistent settings for auto-contrast, sub-pixel coordinates, and auto-fit. It changes the behavior of mouse wheel zooming so the coordinate below the mouse stays fixed when zooming.
Release Notes: This version adds remote control of giv through a JSonRpc protocol. This makes giv suitable for a remote viewer for a running application. There are commands available for changing the image and the vector view of an already running giv, as well as prompting the user to click on a coordinate and retrieving the pixel coordinate.
Release Notes: This is a minor enhancement and bugfix release with the following new features. A pixel grid has been added that may shown at high zoom factors. A new tool allows counting the number of marks in a region. The auto-contrast on file loading may now be turned off. A bug related to multi-slice images in the fits plugin was fixed.
Release Notes: This version contain several small enhancements. The measurement tool now allows dragging the caliper for fine adjustment. The pixel size tool recalculates the distance when toggling between different pixel size modes. The histogram in the contrast tool now shows an indicator of the current gray level when hovering over the image. The TIFF plugin has been extended for floating point and 1-bit images. A PNG (including 16bit) plugin has been added. Alpha transparency for marks may now be toggled on and off. This version also fixes a bug in 64-bit compilation.
