| Summary | 0029350: Visualization, OpenGl_Text - add Aspect_TODT_SHADOW text style | ||||
| Description | Aspect_TODT_DEKALE style makes text readable on arbitrary background by drawing contour of different color. However, due to current limitations, the visual result is not very good and performance is also suboptimal - the text is drawn 5 times to achieve effect (4 times with pixel shift in each direction). The visual representation of Aspect_TODT_DEKALE style can be improved by using more advanced approach, but for now another style Aspect_TODT_SHADOW is proposed to be added. Within new style, a shadow will be drawn with 1 pixel shift in bottom-right direction (thus 2 times to draw whole text), which is less expensive than Aspect_TODT_DEKALE and looks more natural. | ||||
