Drawing Text or Strings on Camera Frames with RockRGA in rkipc
Posted: 2024-11-22 14:39
I am currently modifying the rkipc app and working on adding the ability to draw text or strings on camera frames. There is a function in the app (path: video/video.c) that draws lines to create a bounding box:
imfill function on rockrga:
I want to use a similar approach to draw text or characters on the camera frame. Has anyone worked with RockRGA to render text or strings on the frame in a similar manner?
Thank you for your attention, and any information would be greatly appreciated!
Code: Select all
static int rga_nv12_border(rga_buffer_t buf, int x, int y, int width, int height, int line_pixel,
int color) {
im_rect rect_up = {x, y, width, line_pixel};
im_rect rect_buttom = {x, y + height - line_pixel, width, line_pixel};
im_rect rect_left = {x, y, line_pixel, height};
im_rect rect_right = {x + width - line_pixel, y, line_pixel, height};
IM_STATUS STATUS = imfill(buf, rect_up, color);
STATUS |= imfill(buf, rect_buttom, color);
STATUS |= imfill(buf, rect_left, color);
STATUS |= imfill(buf, rect_right, color);
return STATUS == IM_STATUS_SUCCESS ? 0 : 1;
}Code: Select all
