keep RTF formatting when appending RTF files about r2rtf HOT 6 CLOSED

The issue is about this line

https://github.com/Merck/r2rtf/blob/master/R/assemble.R#L64

that needs to be updated as below to avoid duplicate font claim in RTF. Will create a PR to fix the issue.

start <- c(1, vapply(rtf[-1], function(x) max(grep("fcharset",rtf[[1]])) + 2, numeric(1)))

from r2rtf.

Fixed by #129

from r2rtf.

could you attach a few tables that can reproduce the issue?

Please also try the new function in r2rtf, we will need to update r4csr on this topic. Thanks!

sure here is a dummy example:
(1) example_1.rtf has correct formatting (i.e., Arial font both body, header, footer text)
(2) example_2.rtf has correct formatting (i.e., Arial font both body, header, footer text)
(3) example_combined.rtf (use assemble_rtf() to combine example1.rtf and example2.rtf) no longer has correct formatting

Interestingly, the body text is correct (i.e., Arial font) on the first page but reverts to Courier New on the second page. All header and footer font text immediately revert to Courier New.

"example_1"

"example_2"

"example_combined"

from r2rtf.

The code below works as expected.

Table body are both in Courier font from my end.

Could you try the code and see if it works?

For me to find the root cause, please share code that can fully reproduce the issue from your end.

library(r2rtf)
library(magrittr)

file <- replicate(2, tempfile(fileext = ".rtf"))
file1 <- head(iris) %>% rtf_body(text_font = 6) %>% rtf_encode() %>% write_rtf(file[1])
file2 <- head(cars) %>% rtf_page(orientation = "landscape") %>%
              rtf_body(text_font = 6) %>% rtf_encode() %>% write_rtf(file[2])
output <- tempfile(fileext = ".rtf")

assemble_rtf(
  input = file,
  output = "tmp.rtf"
)

from r2rtf.

No problem. See code below. You need to change the "text_font" to something other than Courier (e.g., text_font = 3 below). Courier appears to be the default font the program is reverting to when RTF tables are combined.

library(r2rtf) # Reporting in RTF format
library(magrittr) # Required for %>%

file <- replicate(2, tempfile(fileext = ".rtf"))

file1 <- head(iris) %>%
rtf_page_header(
text = c("Testing Testing Testing"),
text_font = 3,
text_font_size = 10
) %>%
rtf_page_footer(
text = c("Testing Testing Testing"),
text_font = 3,
text_font_size = 10
) %>%
rtf_body(
text_font = 3,
text_font_size = 10
) %>%
rtf_encode() %>%
write_rtf(file[1])

file2 <- head(cars) %>%
rtf_page(orientation = "landscape") %>%
rtf_page_header(
text = c("Testing Testing Testing"),
text_font = 3,
text_font_size = 10
) %>%
rtf_page_footer(
text = c("Testing Testing Testing"),
text_font = 3,
text_font_size = 10
) %>%
rtf_body(
text_font = 3,
text_font_size = 10
) %>%
rtf_encode() %>%
write_rtf(file[2])

output <- tempfile(fileext = ".rtf")

assemble_rtf(
input = file,
output = "tmp.rtf"
)
