I have updated your description to point to issue 3529 rather than 3530. If you feel it should be 3530, please explain why. You need to include a unit test to demonstrate that your code is working as desired. It might also be helpful to include a sample so that we can see the practical effect of your change on the output file. |
I have added a unittest at tests/PhpSpreadsheetTests/Writer/Html/MemoryDrawingOffsetTest.php |
|
Thank you for supplying the test. I have a few minor changes that I would like you to make to it, but won't be able to document those until tonight. |

Changed a sample to illustrate how to add header/footer in Mpdf using setHtmlEditCallback. This uses custom Html tags, and, like body, it appears that these must be defined in the first writeHtml. Adjust writeMpdf to permit this by using a new constant `SIMULATED_BODY_START`, defined as an Html comment, as a delimiter. Sample 21c_Pdf, to which the header/footer code is added, had been introduced with PR PHPOffice#2434 to ensure that the body tag was always in the first chunk. However, PR PHPOffice#3016 accidentally invalidated that test by reducing the number of style lines so that the sample now included the body tag in its first 1000 records rather than afterwards. This change puts it past record 1000 again. Inspecting the results of all the Html/Pdf samples after this change, it turns out that sample 25_In_memory_image was accidentally broken by PR PHPOffice#3535 - the combination of `max-width:100%` (already present before that change) with `position:absolute` (introduced with that change) made the memory drawing disappear from the rendered html when the image occurs in a column after the last column with data in it. It appears that there is no need for max-width (drawings which are not memory drawings do not use it), so it is dropped. The sample is changed to add a second page with a memory drawing, one page with the memory drawing after the last data column, and one with it before. The Html results now reflect the Xlsx result, as they should.
