#STRETCHBLT COPYIMAGE HOW TO#
#STRETCHBLT COPYIMAGE CODE#

This picture is resized on the fly to match the size of the image control passed to the procedure, 'Public Sub RangeToImage' Use the vertical scrollbar to resize the image control and view the rendering. I used the camera control to paste an image of a range onto a hidden worksheet (the sheet 'RangeSnapshot' is visible but you should hide it later).

I tried using the activewindow zoom to resize the range but that did not work. You may be able to adjust your image using the StretchBlt function from the GDI.įor now, here is a hack that will allow Excel to render the image for us before copying it into Steven B's code. The height and width properties are readonly and of the types OLE_YSIZE_HIMETRIC and OLE_XSIZE_HIMETRIC StretchBlt(hdc, domino.bmX+dx, domino.bmY+dy, domino.bmWidth, domino.bmHeight,hdcOldBkg, 0, 0, ScaleScreen(domino.bmWidth ), ScaleScreen(domino.Click to expand.See hidden member of library stdole, 'IPicture' interface.

#STRETCHBLT COPYIMAGE CODE#

The code below is what I had do to stretch the bitmap. Leave CopyImage() / LoadImage() alone by now and start from transferring some StretchBlt tests to gdi32, fix COLORONCOLOR rows drop, maybe support HALFTONE. I used StretchBlt to replace BitBlt method, it work, but then upon dragging the bitmap, it does not work like the one I had previously done, anything wrong with my coding?

The code above I use it to drag a bitmap on my pocketPC but when I try to add a zoom in funtion inside, it does not work well, it does not work like the previous code, how to I solve it? Replace part of new bkg with old backgroundīitBlt(hdcNewBkg, dx, dy, domino.bmWidth, domino.bmHeight,īitBlt(hdcOldBkg, -dx, -dy, domino.bmWidth, domino.bmHeight,īitBlt(hdc, domino.bmX, domino.bmY, domino.bmWidth, domino.bmHeight,īitBlt(hdc, domino.bmX+dx, domino.bmY+dy, domino.bmWidth, domino.bmHeight, HbmOPrev = (HBITMAP)SelectObject(hdcO ldBkg, domino.hbmBkg) īitBlt(hdcNewBkg, 0, 0, domino.bmWidth, domino.bmHeight, HbmNPrev = (HBITMAP)SelectObject(hdcN ewBkg, hbmNew) HbmPrev = (HBITMAP)SelectObject(hdcM em, domino.hbmImage)

HbmNew = CreateCompatibleBitmap(hdc, domino.bmWidth, domino.bmHeight) Create a temp bitmap for our new background Get window and memory dcs for our BitBlt'ing HBITMAP hbmOPrev, hbmPrev, hbmTemp // Handles to bitmaps HBITMAP hbmNew, hbmNPrev // Handles to bitmaps HDC hdcNewBkg, hdcOldBkg // Handles to dcs Void Dragging :: Drag (HWND hWnd, int nX, int nY)
