java - Having trouble with WritableSheet.addImage(WritableImage) -


i'm using jxl (jexcelapi) save excel file, copying existing excel file new file , modifying copy. i've had great success in doing so, except 1 issue.

i'm trying save 2 different png images @ 2 different locations in excel sheet. call following function 2 successive times (once each image), different row index , different pngfile each time:

private static void putpnginexcel(file pngfile, int column, int row, int widthincolumns, int heightinrows, writablesheet worksheet) {     writableimage image = new writableimage(column, row, widthincolumns, heightinrows, pngfile);     worksheet.addimage(image); }

basically, seems if call above function twice, second call should, ie. second png image appears in excel sheet, not first png image. maybe i'm doing silly, i'm wondering if aware of known jxl issue in regard?

i'm not seeing uncaught exceptions being thrown.

i've confirmed valid png files being passed above function both times executed.

i've swapped png file goes each call of above function, , confirmed png associated second function call 1 gets added excel sheet successfully.

i've deleted 1 of calls above function, leaving 1 call, , confirmed see relevant png image on excel sheet should (i tried passing different combinations of png files , row/column indices , worked fine 1 call above function).

i haven't tried more 2 calls, looks recent call above function works.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
