Sellmeyer | I Have now via Ole (Thanks on Andreas Miethe - over ands over again) one funktionierendes lever for Bitmaps (too gif, ico and diverse others Formate) detect can, the then integrally normal on one Bitmapstatic showing can. with the investigation the Size can I me in the drop not yet integrally make friends. who there a idea has - in the code is the place markiert.
here anyway first the code, for a gültiges lever too for large Images to obtain.
If one it in the program more frequently uses, is it sure sinnvoller, The Init-routine only once at the beginning aufzurufen, but so functions it already time klaglos.
Please time with Files larger as 5100 Pixeln testing. currently have I it only with jpg and gif probiert. Icos are so größenmäßig not the trouble.

alas Yes...if FreeProfan and OLE not so right like...my "schlankere" API-Variante comes Yes integrally without OLE from. |

I have straight time nachgeschaut: The XProfan-command and -functions, The Images from Files loading (MLoadBmp, DrawPic, DrawSizedPic and Create("HPIC",...)), benefit a OLE-routine, The on Andreas' code angelehnt is. here ought to it no Problems with large Bitmaps give. I must the time hither to check on.
(This is not for FreeProfan, I FreePascal not yet with OLE-Objects verheiraten could.)

Nachtrag: and too the supra verlinkte africa-Image power in highest dissolution (75 MPixel) no Problems.
there question I but, Why the not at me functions. I Have of course yet XP with 2GB Ram but with my Variante of Andreas' code functions it Yes, means can not generally on the memory or the Windowsversion lying.
Perhaps can you again look, what since the Differences in your Version To of my are.
The verschlankte Code Matthias functions by me incidentally neither. 
Also falls me on, that Matthias print uses, around the Image To process. This will in my code vermieden, separate only through Speicherschiebereien the lever determined. |

I have here on this PC indeed XP SP2 on it. after now Roland no Problems at loading the Bildes having, Have I the whole time quick in a virtual Win 7 probiert. and see there...there there too no trouble!
If itself now the profaninterne code lt. Roland on the OLE-Prozedere of Andreas anlehnt, must But still differences give, because extern funtioniert it Yes through OLE.
the print in my code standing there really only, because I the lever displayed get wished. Why but these API-Variante, The really only GDI(+)-functions uses, with you not goes, is me now again puzzel.
Mysteriös...but at least a step moreover... |

Matthias
Arlt | this is Yes the Mysterium...
GDI+ ought to with XP Yes standardmäßig present his. this is it means vmtl. not.
You could vlt. times the Rückgabewerte schrittweise for each Funktionsaufruf standing. possible lead the something moreover !?
capture can we anyway, that itself create("HPIC" XP (and well only there) with Images of roughly 8000x8000 untypisch behave. no trouble, if to the white or such Images not has.
whom subesquent Passus can You too from the OLE-Variante Remove:
TestHandle& = Create("HPIC",-1,Image$)
Window Title Str$(TestHandle&) + " with very large Images is the Result here 0"
DeleteObject TestHandle&
OLE comes without it from and needed it not (systemunabhängig). therefore is it there m.E. neither helpful (and stiftet vlt. Verwirrung). |

No, I see there too none Handlungsbedarf, after the trouble recognized and eingegrenzt is and it working Workarrounds gives.
with the antiquated with XP is the once in a while not so simply. for defined technical Applications is XP sometimes already something like How the smallest joint denominator, circa unverhältnismäßigen hoisted To avoid. |

Sellmeyer | @Roland; naturally can I whom viewpoint understand - correctly. to accept can I The attitude not.
It's all right not (only) circa a antiquated Windowsversion, separate for a Program. what at a place unnecessary Resources verbrät. there can itself slight on the viewpoint retire, to the customer itself still what New/News buy, then runs it again. But this is a attitude, The in the meantime moreover led has, that PC, The former High-End-machines were, nowadys, hardly yet as Bürocomputer taugen, because self The Schreibprogramm so lavish with Plattenplatz and Ram bypass, that any two years one new PC hermuss, if one with this software Uptodate his wants.
Profan is To Happiness distant of such absurd Auswüchsen, but it bid itself on, the way faithfully To stay, if it still evident a alternative gives, The Yes apparently none so far removes from the ohnehin installed Codeteilen To his shining.
basis of my code, is exactly the code [...] of Andreas. I Have the only in a class gepackt, because me the stature gefällt.
The only Difference is, I the image not whom Olemitteln on the screen bring, separate the lever use, circa it moreover with Profanmitteln To process.
Perhaps is the already the point, where in your code a small Änderung wonder effect could. |
