Abstract

The embodiment of the present invention discloses a text display method and device based on a shared surface, which is used to solve the problem of using GDI to draw text in the prior art, so that the edges of the text will have very obvious jagged edges. If it is enlarged and displayed on a large-scale splicing wall, Jagged edges can be a more noticeable technical problem. The method in the embodiment of the present invention includes: creating a texture according to the D3D device, and obtaining a shared surface from the texture; creating a text drawing target according to the shared surface, setting the text format and layout and creating a text drawing brush; using the text drawing brush according to the text format and layout Draw text on the shared surface.

Description

technical field [0001] The invention relates to the field of computers, in particular to a text display method and device based on a shared surface. Background technique [0002] With the rapid development of society, the transmission of information has become more and more important. Both government agencies and civilian fields have paid more and more attention to the establishment of an information platform for monitoring and management. The large-screen splicing wall has the advantages of clear pictures and good visual effects. Has become the display side of most platforms. In order to manage the signal in a unified way and make it more logical, users usually mark text on the signal image, or play emergencies or the latest information on the large screen in the form of scrolling subtitles, so that the staff can understand in time, so , how to clearly and accurately display static or dynamic text on the video wall to facilitate the daily work of users has become an urgent...
