Convert OTF to Bitmap

former_member96324 — Fri, 01 Apr 2016 08:45:18 GMT

Hi All

How to convert OTF data to Bitmap. Already searched in SCN and there is no thread with complete solution.

Basically, i am using program sapmssco to convert barcode data to OTF but unable to download to .bmp or .jpg or any image extension.

In the program, we have bitmap data but if i download this bitmap data to desktop and when opening the file, it gives error "This is not a valid bitmap file, or its format is not currently supported".

You are trying to do something not provided by SAP. I think the OTF only contains the general barcode parameters, not the graphics, which are in fact generated by the OTF driver (while sending to the printer, it converts the OTF to the Page Description Language of the printer). I don't even know what the OTF driver triggers, ABAP program or system program.

If you just need barcode bitmap image, check how the barcode printing example program (RSPO0031) works. It generates the bitmap image to show that in the print preview.

Subroutine: brltest_preview, renderbarcode.

This is also called when you try to convert OTF to PDF. OTF data for barcode is converted to a bitmap image to be included in the PDF file.

Hence, I feel that, the conversion routines from barcode OTF to its bitmap, exists in ECC.... just need to be explored.

Thanks, Juwin

Hi Juwin

Thanks for your reply. The program and code you mentioned are the same which i mentioned in my original post (sapmssco).

As i already told, bitmap data exist but if i download this bitmap data using GUI_DOWNLOAD, then upon opening file it gives error ""This is not a valid bitmap file, or its format is not currently supported"'.

It seems, need to add additional header details to download into proper bitmap which i am not able to get. If you have any other inputs, let me know.

I guess the returned format contains the bitmap, but is not exactly a BMP file. SAPMSSCO adds a header which is only for OTF ("OTFbitma..."). Instead, we should add a header part for BMP files -> https://en.wikipedia.org/wiki/BMP_file_format

I don't even know what exact BMP format is returned by RENDERBARCODE subroutine (monochrome probably...)

Hi,

Have a look at subroutine FILL_BMFILE_FROM_BMP in program LSTXBITMAPSF03. It has decoding logic to read from BMP file. Probably you may be able to reverse engineer and encode the BMP header.

Thanks, Juwin

Beautiful.....!!!

In the code snippet above, the field symbol name is missing. Please correct it.

data length type i.

data hex type xstring.

data bitmap3 type xstring.

FIELD-SYMBOLS <fs> type x.

clear: hex, bitmap3.

loop at otf.

length = otf-tdprintpar+2(2).

assign otf-tdprintpar+4(length) to <fs> casting.

hex = <fs>(length).

concatenate bitmap3 hex into bitmap3 in BYTE MODE.

endloop.

Thanks.

I really hope you're not suggesting that a field symbol should have the name <fs>. That would make me sad.

@Juwin, sorry I don't have the edit button anymore to correct it

(that's because I need to workaround the SCN editor which doesn't work well with my IE 11)

@Matt, my code is often very ugly when I rush!

Sandra, don't worry: Nobody loves the SCN editor as it just doesn'do what we can expect.

Time to dump it!

Just look at the downgoing usage of SCN after it tried to be facebook 🙂

Sorry, couldn't resist.
