save_as_image alignment issues
rosiebae opened this issue · 2 comments
Hi, this is my first time posting so please let me know if I'm doing anything incorrectly.
I'm using the save_as_image
function to save a table as a PNG file. I've been noticing that in some instances, an alignment issue occurs. Generally, it happens when I merge cells. There's no issue when I view the table in R Studio, but when I save it as an image, the issue pops up. Please see example screenshots below:

Please find a minimal reproducible example below:
library(flextable)
library(tidyverse)
# Create mock data
text <- "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
source1 <- "DATA_SOURCE_A.COURSE_TITLE\nDATA_SOURCE_A.SUBJECT_DESCR\nDATA_SOURCE_A.CATALOG_NUMBER"
source2 <- "DATA_SOURCE_A.GRADING_BASIS\nDATA_SOURCE_A.OFFICIAL_GRADE\nDATA_SOURCE_B.STUDENT_GROUP"
temp_dat <- data.frame(
label = c("Sources", "", "Notes"),
col1 = c(source1, "", text),
col2 = c(source2, "", text)
)
# Create table
temp_tbl <- flextable(temp_dat) %>%
bg(bg = "#FFFFFF", part = "all") %>%
merge_h(part = "body") %>%
font(fontname = "Calibri", part = "all") %>%
align(align = "left", part = "all")
save_as_image(temp_tbl, path = "temp_tbl.png", res = 300, expand = 0)

thanks for opening the issue (it's perfectly reproducible, don't worry)
We improved the rendering of text wrapping (note support for \t
is also improved) but there are still misalignment, especially when the text is right aligned. You can test with the dev version
