Conflicting demands arise in the implementation of class Fl_Xlib_Graphics_Driver for drawing images with the XRender library : 1) Issue #163 leads to use a bilinear filter to draw-and-scale images. 2) This tends to blur the edges of drawn areas which is bad for tiled images (that is because the edges get alpha values, even for an opaque source image). This commit resolves the conflict adding a means to detect whether the library is busy drawing a tiled image. If so, the bilinear filter is not applied, drawn areas don't have blurred edges, resulting in a nice tiling. With this commit, these test apps perform correctly: - tiled_image is correct at all scaling factor values also when modified to use a depth-3 or a depth-4 Fl_RGB_Image as tile; - unittests - Drawing Images is correct at all scaling factor values; - pixmap_browser scales correctly up and down JPEG and PNG images. |

README - Fast Light Tool Kit (FLTK) Version 1.4.0
WHAT IS FLTK?
The Fast Light Tool Kit ("FLTK", pronounced "fulltick") is a
cross-platform C++ GUI toolkit for UNIX®/Linux® (X11 or
Wayland), Microsoft® Windows®, and macOS®.
FLTK provides modern GUI functionality without the bloat and
supports 3D graphics via OpenGL® and its built-in GLUT
emulation. It was originally developed by Mr. Bill Spitzak
and is currently maintained by a small group of developers
across the world with a central repository on GitHub.
