Changing the file type of photos in Powerpoint presentation using VBA? -


i have powerpoint presentation photo on each slide large file size (.emf). change them .png make final file size smaller.

so far, have this:

sub convertshapetopng()     dim osh shape     set osh = activewindow.selection.shaperange(1)     osh.copy     activewindow.selection.sliderange.shapes.pastespecial pppastepng     osh.delete end sub

this take picture selected on slide , replace png. having trouble having work throughout presentation wants me select picture first.

this code full presentation version:

sub convertallshapestopng()  dim osld slide dim osh shape  each osld in activepresentation.slides     each osh in osld.shapes         set osh = activewindow.selection.shaperange(1)         osh.copy         activewindow.selection.sliderange.shapes.pastespecial pppastepng         osh.delete     next next osld  end sub

can me run code throughout entire presentation? thanks!

edit: ideal if photos copy same location original photo instead of copying centre of slide have not tried myself yet.

i figured out myself!

here code if curious:

sub convertallshapestopng() 'purpose: change pictures .png images  dim shp shape dim sld slide dim pic shape dim shp_left double dim shp_top double  'loop through each slide in activepresentation   each sld in activepresentation.slides     each shp in sld.shapes        if shp.type = msopicture         'retrieve current positioning           shp_left = shp.left           shp_top = shp.top          'copy/paste .png picture           shp.copy            sld.shapes.pastespecial datatype:=pppastepng            set pic = sld.shapes(sld.shapes.count)          'delete linked shape           shp.delete          'reposition newly pasted picture           pic.left = shp_left           pic.top = shp_top        end if      next shp   next sld    msgbox "all photos .pngs"  end sub

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
