 <p>GraphicEx and PngComponents and pngimage are conflicting. To solve it:</p> <p>1) always put them in uses clause in specific order - first - GraphicEx or PngComponents, last - pngimage.</p> <p>2) build Project. It is not enough to run (or compile) project after uses clause was changed.</p> <p>PS) pngimage installed with PNGcomponent package, BUT this version is outdated </p>
